Industrial Pins
Industrial pins are cylindrical fasteners that are used to locate, align and join components. They are made out of aluminum, brass, titanium, wood and plastic. Products made from hardened steel, unhardened steel, and stainless steel are also available. There are several basic types of industrial pins. Categories include dowel pins, spring pins, cotter pins and wire clips, hitch pins and linch pins, locating and fixture pins, and specialty products. Some industrial pins use the English or imperial system and are measured in inches or fractions of an inch. Others use the metric system and are measured in millimeters or centimeters. Important dimensions for industrial pins include inner diameter (ID), outer diameter (OD), and length.

 

Dowel pins are industrial pins that are used to prevent motion or slippage. Straight, oversize, undersize, and knurled products are commonly available. Parallel dowel pins have ends that are machined to two different tolerances. Stepped dowel pins have two different body diameters altogether. Pull dowel pins have a threaded hole in one end so that a screw can be inserted to help remove the pin from a blind hole. Threaded and non-threaded taper pins are also available. Standard groove pins contain longitudinal grooves. By contrast, spiral groove pins contain latitudinal grooves. Escutcheon pins have a semi-spherical head at one end and a long cone at the other. They are usually hammered in place and used for light-duty jobs. Drive pins feature an interference fit and are often used to assemble components in rotary or other moving applications.

Industrial pins include several types of spring pins, cotter pins and wire clips. Coiled spring pins are hollow and made of metal. Roll pins or slotted steel springs are headless, hollow fasteners with a longitudinal slot that runs down the length of the pin. Cotter pins open out after passing through a hole. The most popular type is the extended or hammerlock cotter pin; however, hairpin and circle (ring) cotter pins are also available. Twist pins feature a self-locking mechanism and can be used as replacements for standard hairpin cotters. Clinch pins are manufactured with a hump on one end and are self-securing. Industrial-quality safety pins are commonly available.

There are many types of hitch pins, linch pins, locating pins, and fixturing pins. Hitch pins have a wire loop grip at one end. Linch pins also have a ring-shaped loop, but snap into place. Clevis pins have a head on one end and a hole in the other. Like hitch pins and linch pins, clevis pins are used in conjunction with cotter pins. Other types of hitch pins include toggle pins, detent pins, and wire locks. A variety of locating and fixturing pins are available. Examples include clamping pins, quick release pins, drift pins, and indexing or pop pins. L-pins and T-pins have a letter-shaped handle at one end. Round pins and diamond pins have either a small or large locating shoulder. Cone locator pins can compensate for a great deal of misalignment. Floating locating pins are used provide precise, 1-axis location while floating in the perpendicular axis.

Industrial pins include many types of specialized or proprietary products. Ejector pins are small fasteners that are designed to push or eject parts or materials. Expanding diameter pins expand when a cam is actuated to provide a tight fit. Shear pins are designed to break if the fastened components move in opposite, parallel directions to their mating surfaces. Weld pins are designed to be welded in place. Some specialized industrial pins are sold in bulk packages. Others are sold in packages with assorted sizes
