Components used to fasten or secure one part to another, such as screws, rivets, bolts, nuts, and clips.
Anchors are mechanical fasteners that attach an object to a support structure. Product categories include concrete anchors, expansion anchors, lag screw anchors, machine anchors, screw anchors, spring anchors, wall anchors, and wedge anchors. Toggle bolts are also available.
Strapping and banding are used to secure items for shipping or storage or as a clamp to secure an assembly together.
Beam clamps attach conduits, pipework, panels, or other hardware to the flanges of structural beams.
Bolt tensioners are used in place of standard hex nuts or bolts for easier and more precise tightening of large-diameter bolt and stud assemblies. They are sometimes called multi-jackbolt tensioners (MJTs).
A bolt is a type of threaded hardware fastener that is used to position two workpieces in specific relation to each other. A bolt is specifically designed to be used with a mating, internally threaded hole or nut, which will maintain the bolt's alignment as well as the material's position on the bolt. While used synonymously, screws and bolts are not mechanical clones.
Captive fasteners are designed for permanent retention within their target assembly or housing, often even upon servicing, providing a secure joint and avoiding loss or damage that might be caused by a loose part.
Fasteners designed for ease of installation - often knurled for finger use - and retained within their functional environment when not engaged. Captive screw (or bolt) retention prevents loss or damage within the captive screw's parent assembly, or damage to components in the nearby working environment.
Clevises are U-shaped fasteners that are used with a clevis pin to connect to a tang or clevis mount. Clevis fasteners are used to connect products such as cylinders, trailers and structural members subjected to tension loads only. Clevis fasteners are used in many industries, such as agriculture, marine, aerospace, construction, and manufacturing.
Compression limiters are a type of insert or bushing designed to protect plastic parts from damage by limiting the compressive force from the assembly bolts.
Cotter pins and wire clips are penetrating and coupling mechanical fasteners. They are easy to install and remove. Cotter pins come in several forms, with each designed for a specific kind of assembly. Some cotter pins are suitable for use as shear pins.
Dowel pins are industrial fasteners that are used to assemble two or more items together. They are short, cylindrical rods. The dowel pins can be tapered, slotted, grooved, or otherwise altered to change its mechanical properties. They are commonly available in imperial or metric units.
Hitch pins and their variations are simple forms of hardware used to temporarily mount or conjoin mating components. Linch pins are specifically designed to retain wheels or other rotating devices on their axles, but can be used as a fastener as well. Both of these types of pins require mating holes and some form of a lock to be effective.
Hook and loop fasteners consist of two layers of fabric. The hook layer is covered with tiny hooks and the loop layer is covered with tiny loops. Hook and loop fasteners are commonly known as Velcro®. Velcro is a registered trademark of Velcro Ind.
Industrial pins are varieties of fastening hardware meant to couple, align, mount, assemble, or penetrate two workpieces. The operation of the pin depends on design and employment, but industrial pins can be categorized into several categories, such as: hitch and linch pins; cotter pins and wire clips; spring pins; locating and fixturing pins; and specialty pins.
Locating and fixturing pins are press-fit, removable hardware devices designed to align or affix two work pieces to very small tolerances. When translation mechanisms are not stable or precise enough to place objects in position for a particular process, locating and fixturing pins can ensure an accurate alignment.
Lockbolts are two-piece fasteners that consist of a headed, parallel-shank pin with a serrated end and collar. An assembly tool is used to swage the collar onto the serrated grooves in the pin and break the stem flush to the top of the collar.
Locknuts are a type of prevailing-torque fastener that resists loosening under vibration and torque. They differ from standard nuts because they typically have friction-increasing bearing surfaces (e.g., pitted grooves on flanges) or special internal thread-geometries.
Nails are available in a variety of shapes and sizes for specific uses. Common nail types include: brad nails, cap nails, common nails, double-headed nails, finishing nails, masonry nails, roofing nails and screws.
Nuts are a type of hardware fastener with a tapped inner diameter. They are used with a mating threaded bolt or rod to secure components. There are many sizes and varieties of nuts; each with a particular fastening purpose. Some nuts can be applied without tools, and others may have special designs to prevent the nut from loosening.
Precision adjustment screws have fine threading up to 200 TPI and provide micro positioning on tables, microscopes, analytical intruments, and flow metering devices.
Precision locknuts are used to secure bearings, gears, and other power transmission products to shafts and spindles.
Preload springs, spacers, and washers are meant to maintain tension in an assembly where some slack may be present. Their capabilities can eliminate rattle, compensate for expansion or contraction of the assembly materials, or absorb intermittent shock loads. These products are made of elastic deformable materials, most commonly convoluted ductile, high-strength metal alloys which come in machined, welded, and open-ring varieties.
Push on fasteners are hardware that quickly and securely assemble components on a shaft without the need for tooling or rotational torque.
Push-in rivets are cylindrical, headed, usually plastic fasteners that are pushed or pressed into place to secure two or more items together.
Quarter turn fasteners are fasteners which must be subjected to a quarter turn motion to properly assemble.
Retaining rings and snap rings are fasteners used to axially position a component on a shaft or in a bore.
Rivets are headed pins with a point that passes through two pieces of material. Beating or pressing down the point causes it to spread out and form a second head. Rivets can be used to connect two plates or pieces of material together.
A screw is a wide-encompassing type of hardware fastener that attributes its mechanical capabilities to the helical groove that extends around the circumference of the device's shank. These threads provide the friction and traction that serves a screw's purpose: to assemble or position two workpieces in relation to each other. While used synonymously, screws and bolts are not mechanical clones.
Self-sealing fasteners have an elastomeric insert or captive O-ring that simultaneously provides sealing and locking.
Shoulder screws, also called stripper bolts, are a type of machine screw with integral threads that are only present on half or less of the screw shank. A shoulder screw has a partially smooth shaft that will allow the bolted material some rotation and movement around the screw axis, while the threaded end will typically have a nut to maintain the screw's position.
Snap fasteners or snaps are mechanical fasteners that close or lock with a clicking or snapping sound.
Specialty pins are specialty or proprietary industrial pins.
Spikes are long, thick, sharp-pointed fasteners made of metal or plastic. They are similar to heavy nails and used in railroad ties and other heavy-duty construction applications.
Spring pins are hollow dowel pins manufactured from spring steel.
Spring washers, sometimes called disc springs, lend their mechanical capabilities to the unique profile of the material: the irregularities of the washer compress with a proportionate resistance to return to their predeflected shape. Spring washers are employed in applications where assemblies need a part to take up play, maintain assembly tension, compensate for expansion or contraction in materials, or to absorb intermittent shock loads and provide a controlled reaction under dynamic loads.
Staples are U-shaped metal fasteners that are driven into a surface to hold or secure an object in place.
Studs are mechanical fasteners which are threaded on one or both ends. One end is secured to an object. The other end is used typically with a nut.
Threaded inserts are blocks of material with a threaded hole that are pressed or molded into a part, usually made of a different material.
Threaded rod is a fastening bar or rod threaded along its length.
Tolerance rings are radially sprung rings that fit between two mating components to act as frictional fasteners.
Washers are disks of metal or non-metallic material placed beneath a nut, an axle bearing, or a joint, to relieve friction, prevent leakage, isolate, prevent loosening, or distribute pressure.
Wave washers or wave springs are wavy metal washers designed to provide a compensating spring force and sustain a load or absorb shock.
Zippers are temporary fasteners consisting of two strips of fabric each with tens or hundreds of specially shaped plastic or metal teeth. A slider joins the two sides by pushing the teeth together as it rides along the two sets of teeth.
