Type
   Type       
   Your choices are...         
   Castle Nut       Castle nuts have slots or notches that are cut into one end to allow a cotter pin or safety wire to assist in fastening. Castle nuts resemble a chess-playing piece and are also known as castellated or slotted locknuts. 
   Distorted-Thread Locknuts       Distorted-thread locknuts use a deformed section of thread to prevent loosening due to vibration from or rotation of the clamped item. Types include centerlock, elliptical-offset, toplock, oval, and non-slotted hex. 
   Flex-Top Locknuts       Flex-top locknuts are made from a single piece of material and have a slotted top that expands as the nuts are tightened. This locks them into place and provides vibration resistance. Flex-top locknuts are also known as flex-loc or split-beam locknuts. 
   Nylon Insert Nut       Nylon insert nuts use a plastic insert to capture the bolt or screw. Nylon nuts are used in applications where vibration or motion could loosen or undo the nut. 
   Interfering Threadnuts       Interfering thread nuts are a type of locknut that has an over-sized root diameter to provide permanent or semi-permanent joining. These fasteners are also known as tapered thread nuts. 
   Jam Nut       Jam nuts are typically half the height of a standard nut. Often, these locknuts are pushed-up or jammed against a standard nut in a fastener assembly to provide an additional securing force. 
   Jet Nut (K-Nut)       Jet nuts or K-nuts are smaller, flanged-type locknuts that are often used in aerospace or automotive racing applications. 
   Speed Nuts (Sheet metal / Tinnerman Nuts)       Speed nuts (sheet metal nuts, tinnerman nuts) can be quickly pushed into place using deformable teeth instead of standard threads. These fasteners are used for light-duty applications, either alone or with a traditional threaded nut in a fastener assembly. 
   Two-Piece Locknuts       Two-piece locknuts are sold as two-component, upper and lower nut assembly pairs. They provide a greater joining force in high-vibration applications. Two-piece locknuts are also known as drake-style or two-piece thread-clamping locknuts. 
   Other       Other unlisted locknut types.

Material / Finish
   Material       
   Your choices are...         
   Aluminum       Aluminum is a bluish, silver-white, malleable, ductile, light, trivalent, metallic element that has good electrical and thermal conductivity, high reflectivity, and resistance to oxidation.  Aluminum is lighter than steel, but not as strong. 
   Brass       Brass provides good strength, excellent high-temperature ductility, reasonable cold ductility, good conductivity, excellent corrosion resistance, good bearing properties and low magnetic permeability. 
   Bronze / Copper Base Alloy       Copper base alloys are metals with copper as their main alloying metal, and one or more other metals such as tin, zinc, or phosphorus. Silicon bronze is a typical fastener alloy. 
   Copper       Copper is a common, reddish, metallic element that is both ductile and malleable. Copper is one of the best conductors of heat and electricity. It also exhibits good corrosion resistance. 
   Exotic Metals       Exotic metals and alloys have specialized properties. This category includes materials such as Hastelloy®, Monel®, beryllium copper, beryllium nickel, niobium, tantalum, titanium and zirconium. 
   FRP       Fiber-reinforced plastic (FRP) or fiber-reinforced polyurethane is a composite material with reinforcing fibers. It is stronger than many plastics which do not contain reinforcing additions. When made with polyurethane, FRP is a tough and wear-resistant material. 
   Inconel® / Incoloy®       Inconel® and Incoloy® (Special Metals Corporation) provide good strength and excellent resistance to oxidation and carbonization in high temperatures environments, and in many aqueous environments. These proprietary materials are used in process piping, heat exchangers, heating element sheathing and nuclear steam generator tubing. Typically, Inconel and Incoloy are used at service temperatures below 650° C (1200° F). 
   Monel®       Monel® (Special Metals Corporation) is a proprietary, high-strength material that offers resistance to a range of corrosive media such as seawater, hydrofluoric and sulfuric acids, and alkalis. 
   Nylon       Nylon is a tough, resistant, general-purpose material. It comprises several grades of polyamides and has good pressure ratings. Nylon 6/6 is commonly used with fasteners. 
   Plastic       Products are made of thermoplastic materials. 
   PTFE       Polytetrafluoroethylene (PTFE) is an insoluble compound that exhibits a high degree of chemical resistance and a low coefficient of friction. It is sometimes marketed in proprietary classes of materials such as Teflon®, a registered trademark of DuPont Dow Elastomers. 
   PVC       Polyvinyl chloride (PVC) is a widely used material that has good flexibility, a smooth surface, and nontoxic qualities. Some grades are used in food and chemical processes because of PVC’s inert nature and good resistance to chemicals such as acids and alcohols. PVC brand names include ACP® and Dural® (Alpha Gary), Geon® (Geon), Benvic® (Solvay), and Flexalloy® (Teknor Apex). 
   PVDF       Polyvinylidene fluoride (PVDF) is a melt-processable fluropolymer. PVDF has similar properties to other fluropolymers, but provides better strength and lower creep. PVDF also offers good wear resistance and excellent chemical resistance; however, it does not perform well at elevated temperatures. Brand names include Kynar® (Elf AtoChem). 
   Rubber       Synthetic rubber includes grades such as neoprene, silicone, and Norprene® (Norton Co.). Rubber fasteners are used in specialized applications for vibration damping and silencing. 
   Steel       Steel is a commercial iron that contains carbon in any amount up to about 1.7 percent as an essential alloying constituent. Many grades of carbon and alloy steels are used as fastener materials. Steel may require coating for protection against corrosion. 
   Hardened Steel       Steel can be hardened in a number of ways. Methods include quenching techniques in oil and water, and passing the steel through induction chambers. During processing, the rapid cooling of steel freezes, traps and packs the carbon atoms inside the shrunken iron crystals. The resulting steel is very hard and brittle. Hardened steel is strong, but cannot absorb much shock or impact without breaking. 
   Stainless Steel       Stainless steel is chemical and corrosion resistant and can have relatively high stress ratings. Many grades are used in fasteners. Often, stainless steel does not require an anti-corrosion coating; however, most stainless steels cannot be hardened to the same degree as carbon steels. 
   Titanium       Titanium is a hard, lustrous, silvery element that is relatively abundant in the Earth's crust. It is valued for its lightness, strength, and corrosion resistance.  Titanium is used widely in the aerospace industry and in medical products such as replacement joints. When alloyed with other metals, especially steel, titanium adds strength and oxidation resistance. 
   Other Metal       Other unlisted, specialized, or proprietary metallic materials. 
   Other Plastic       Other unlisted, specialized, or proprietary non-metallic materials.

   Finish       
   Your choices are...         
   Anodize       Anodizing is a process for finishing aluminum alloys that uses the electrolytic oxidation of the aluminum surface to produce a protective oxide coating. The anodic coating consists of hydrated aluminum oxide and is resistant to corrosion and abrasion. Conventional coatings are 0.1 to 1.0 mils thick and are mostly transparent, but may be colored. Anodizing preserves the natural luster and texture of the metal. Anodized coatings are hard, durable, will never peel, and, under normal conditions, will never wear through. Standard and decorative colors are available. This category includes hard-coat anodizing. 
   Anti-Galling Coating       Anti-galling is a fastener thread surface-damage prevention feature. It prevents or reduces friction-caused thread damage to the bolt and mated nut. This property comes from a special material surface treatment that lowers the coefficient of friction between mating surfaces, by use of treatments like zinc or tin. 
   Black Oxide       Black oxide is a conversion coating that causes virtually no dimensional change. It is a uniform, continuous conversion of the existing metal to a black form of rust. Black oxide is used on components where tight tolerances are needed. It is used mostly as a decorative coating. 
   Chrome       Chrome finish is an electroplated coating that is applied for purposes of lubricity, wear resistance, and decoration. Chrome provides a bright and highly reflective finish. 
   Galvanized       Galvanizing immerses clean, oxide-free iron or steel into molten zinc in order to apply a zinc coating that is metallurgically bonded to the iron or steel surface. The zinc coating protects the surface against corrosion in two ways. First, it shields the base metal from the atmosphere. Second, because zinc is more electronegative than iron or steel, the coating reacts with corroding agents, providing a longer service life for the part. 
   Gold       Gold plating provides total resistance to oxidation and corrosion. It is electrically conductive and can be alloyed with cobalt to produce a wear-resistant finish. 
   Phosphate       Phosphate coatings are applied via the chemical or electrochemical treatment of a metal’s surface. These corrosion-resistant coatings provide a surface for the improved adhesion of primers and paints. 
   Nickel Plated       Nickel plating is a common form of electrolytic deposition. 
   Silver       Silver is the most electrically conductive plating finish. It is used in electronic fasteners for electrical conductivity and signal transmittance. Silver oxidizes rapidly, but resists corrosion. 
   Tin       Tin plating is applied to electronic fasteners that are made of brass. 
   Zinc Plated       Zinc plating is a common form of plating that provides corrosion resistance. 
   Zinc Chromate (Yellow)       Fasteners have a yellow zinc chromate finish. 
   Other       Other unlisted finish.

Fastener Standards
   Standards       
   Your choices are...         
   AIA / NAS       Dimensional and material standards for aircraft fasteners are developed by the Aerospace Industries Association (AIA) and/or its National Aerospace Standards Committee (NASC). All drawings and specifications have a NAS or NASM prefix. NAS is an acronym for National Aerospace Standards. NASM is an acronym for National Aerospace Standards, Metric. 
   AN / MS       Dimensional standards for aircraft fasteners are developed by the Aeronautical Standards Group. All drawings have a prefix of AN or MS. Products are suitable for army, navy, or air force use.  
   ASME / ANSI       The American Society of Mechanical Engineers (ASME) B18 standard specifies all ASME B18 fastener products with a single 18-digit PIN code system. Approved by the American National Standards Institute (ANSI) and adopted by the U.S. Department of Defense, the ASME B18.24 PIN system is a self-contained code that covers 788 unique B18 fastener types from 72 ASME B18 source documents. The PIN code system is fully parametric, uniform across all fastener types, and is intended as a digital alternative to the traditional plain text fastener product callout prescribed in the "Designation" or "Ordering" section of the applicable source document. 
   BS       Dimensional and material standards developed by the British Standards Institution.  Standards are designated with a BS prefix.  The British Standards International (BSI) Kitemark indicates that products are tested regularly against the requirements of an appropriate BSI standard, and that the manufacturer's quality system is assessed at least twice a year to ensure continued quality production.  
   DIN       DIN is an acronym for Deutsches Institut für Normung (DIN), a German national organization for standardization. Most metric fasteners are manufactured according to DIN standards. Although DIN predates the International Standards Organizations (ISO), DIN standards are being revised to more closely match ISO standards. Ordering DIN fasteners requires three pieces of information: the DIN identifier, which defines the style of the fastener; the material (e.g., 8.8 Steel, 316 Stainless, Hastelloy C276); and the coating or plating (if any). 
   ISO       The International Standards Organization (ISO) is a worldwide federation of national standards organizations from over 100 countries. ISO's mission is to facilitate the international exchange of goods and services, and to foster cooperation in the spheres of intellectual, technological, and economic activity. ISO standards for metric fasteners are gaining recognition rapidly. They will probably become global standards. 
   JIS       Japanese Industrial Standard (JIS) is largely based on DIN; however, some standards have been modified to meet the needs of the Japanese market. Most of the fasteners used in electronic equipment manufactured in Japan comply with the JIS standard. 
   SAE       Fasteners meet standards developed by the Society of Automotive Engineers (SAE), a worldwide organization that establishes industry standards for the testing, measurement, and design of automobiles and their components. 
   Other       Other unlisted, specialized, or proprietary fastener standards.
