Hitch Pins and Linch Pins (91 suppliers)
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.

Industrial Pins (769 suppliers)
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 (59 suppliers)
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 (39 suppliers)
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 (159 suppliers)
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.

Preload Springs, Spacers, and Washers (89 suppliers)
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.

Screws (1,321 suppliers)
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.

Shoulder Screws (86 suppliers)
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.
