Material / Finish

	Metallic
	Your choices are...
	Aluminum		A bluish silver-white, malleable, ductile, light, trivalent, metallic element that has good electrical and thermal conductivity, high reflectivity, and resistance to oxidation.  Lighter and less strong than steel.
	Brass		Brass comes with good strength, excellent high temperature ductility and reasonable cold ductility, good conductivity, excellent corrosion resistance, good bearing properties and low magnetic permeability.
	Bronze / Copper Base Alloy		A copper base alloy is metal composed of copper as the main alloying metal and one or more other metals, such as tin, zinc, or phosphorus.  Silicon bronze is one typical fastener alloy.
	Copper		A common reddish metallic element that is ductile and malleable and is one of the best conductors of heat and electricity. Also exhibit good corrosion resistance.
	Inconel® / Incoloy®		An alloy, which combines good strength and excellent resistance to oxidation and carbonization in high temperatures and many aqueous environments. Used for process piping, heat exchangers, heating element sheathing and nuclear steam generator tubing. Generally used at service temperatures below 650°C (1200°F). Incoloy® is a registered trademark of Special Metals Corporation.
	Monel®		Monel® alloy has high strength and resistance to a range of corrosive media including seawater, hydrofluoric and sulfuric acids, and alkalis. Monel is a registered trademark of Special Metals Corporation.
	Steel		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 steel are used as fastener materials; may require coating to protect against corrosion.
	Hardened Steel		Steel may be hardened in a number of ways, including a variety of quenching techniques in oil and water, being passed through induction chambers, etc. Quickly cooling steel during processing freezes, traps and packs the carbon atoms inside the shrunken iron crystals, thereby producing a very hard and brittle metal. Although very hard, it 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 used in fasteners; often does not require anti-corrosion coating, but 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 known for its lightness, strength, and corrosion resistance.  For this reason it is used widely in the aerospace industry and the medical fields (e.g., replacement joints).  When alloyed with other metals, especially steel, it adds strength and oxidation resistance.
	Other		Other unlisted, specialized, or proprietary metallic materials.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
	Non-Metallic
	Your choices are...
	Plastic		Includes all types of thermoplastic material.
	FRP		Fiber-reinforced plastic, or often, fiber-reinforced polyurethane.  This composite material has reinforcing fibers to make it stronger than many plastics alone.  When made with polyurethane, it is a strong, tough, wear-resistant material.
	Nylon		Nylon, comprising several grades of polyamides, is a general-purpose material in wide use; it is tough and resistant and has good pressure ratings.  One common nylon grade used for fasteners is Nylon 6/6.
	PVC		Polyvinyl chloride (PVC) is a widely used material that has good flexibility, smooth surface, and nontoxic qualities. Some grades are used in food and chemical processes due to the inert nature of PVC. Brand names include: ACP® and Dural® (Alpha Gary), Geon® (Geon), Benvic® (Solvay), Flexalloy® (Teknor Apex).  Good resistance to chemicals such as acids and alcohols.
	PVDF		Polyvinylidene fluoride (PVDF) is a melt processable fluropolymer. It is similar in properties to other fluropolymers, but has better strength and lower creep than the other members of this family. PVDF has good wear resistance, and excellent chemical resistance. But does not perform well at elevated temperatures. Brand names include: Kynar® (Elf AtoChem).
	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.
	Rubber		Synthetic rubber includes many grades such as Norprene®, neoprene, and silicone; rubber fasteners are used in specialized applications for vibration damping and silencing.  Norprene is a registered trademark of Saint-Gobain Performance Plastics.
	Other		Other unlisted, specialized, or proprietary non-metallic materials.

	Finish
	Your choices are...
	Anodize		Anodizing is a process for finishing aluminum alloys that employs electrolytic oxidation of the aluminum surface to produce a protective oxide coating. The anodic coating consists of hydrated aluminum oxide. It is considered resistant to corrosion and abrasion. Conventional coatings are 0.1 to 1.0 mil thick and are mostly transparent, but may be colored.  Anodizing preserves the natural luster, and texture of the metal itself. An anodized coating is 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.
	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. Used primarily on components where tight tolerances are needed; mostly as a decorative coating.
	Chrome		Chrome finish is an electroplated coating of chromium, applied for purposes of lubricity, wear resistance, and decoration, as it is a bright and highly reflective finish.
	Galvanized		Galvanizing is the practice of immersing clean, oxide-free iron or steel into molten zinc in order to form a zinc coating that is metallurgically bonded to the iron or steel surface. The zinc coating protects the surface against corrosion by providing protection to the iron or steel in two ways. It shields the base metal from the atmosphere and because it is more electronegative than iron or steel, the zinc reacts with corroding agents first, providing a longer service lifetime for the part.
	Gold		Gold plating can be used for its total resistance to oxidation and corrosion, and for extremely good electrically conductive properties.  It can be alloyed with cobalt to produce wear-resistant finishes.
	Nickel Plated		Applying a nickel surface to another material.
	Phosphate		A coating produced by a chemical or electrochemical treatment of the metal surface.  The coatings provide corrosion resistance and provide a surface for better adhesion of primers and paints.
	Silver		Silver is the most electrically conductive plating finish, and can be used in electronics fasteners for electrical conductivity and signal transmittance.  Silver will oxidize rapidly, but resists corrosion well.
	Tin		Tin plating is often used on electronic fasteners, typically of brass material.
	Zinc Plated		Applying a zinc surface to another material.
	Zinc Chromate (Yellow)		Applying a yellow zinc surface to another material.
	Other		Other not listed finish.

Fastener Standards

	Fastener 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.
