The Type A Pin has three full-length tapered grooves. This popular type is used in applications requiring excellent locking effect and ease of assembly. It is widely used in place of taper pins, rivets, set screws and keys. Typical applications include keying sprockets, gears, collars, knobs, handles, levers and wheels to shafts.

The Type C Pin has three parallel grooves extending one-quarter its overall length. It is ideally suited for linkage or pivot applications, especially where a relatively short locking section and longer free length are required. Widely used in certain types of hinge applications. The long lead permits easy insertion.

Type E has three parallel half-length grooves located equidistant from each end. Widely used as T handle on valves and tools. Also used as a cross pin, cotter pin, pivot pin, etc., where center locking is required.

Type G has three parallel half-length grooves including pilot. It is a very versatile pin, suitable for use in both blind and through holes as a spring anchor pin. The annular groove opposite the locking end is used to anchor the end loop of a tension spring. If snap or retainer rings are to be used, special section annular grooves can be machined to order.

Type H grooved pin has three parallel grooves for half the length of the pin. This type of pin may be used as a pivot, stop or hinge pin. When pressed in place, the grooved portion locks in one part while the ungrooved section remains free to serve as the locator, hinge, etc.

Type U has three parallel grooves extending the full length of the pin. A short pilot at each end permits hopper or automatic feeding. Identical ends speed manual insertion as operator need not examine pin to determine proper end to start. Full length parallel grooves provide maximum locking effect. Typical applications include keying gears, collars, knobs, handles, etc., to shafts.

Type D has three reverse taper grooves extending one-half the length of the pin. Recommended for use in blind holes as a top pin, roller pivot, dowel, or for certain hinge or linkage applications. Reverse taper grooves permit easy insertion in blind holes.

Type B Pins have three tapered grooves extending one-half the length of the pin. This type is widely used as a hinge or pivot pin. Driven or pressed into a straight drilled hole, the grooved portion locks in one part, while the ungrooved portion will remain free. Also excellent for dowel and locating applications.

Type A3 Pins have three full-length parallel grooves with a short pilot to insure easy starting. They are recommended for applications requiring maximum locking effect where severe vibration and/or shock loading are present.

Universal Joints in Hand Tools
Special Type E SHEAR-PROOF™ Pin with center grooves eliminates costly staking and grinding operations and improves product appearance. This pin is easily installed, fits flush and permits plating before assembly.

Eye Bolt Hinge Pin
Type C pin, with quarter-length grooves, provides maximum ease of assembly. There is no interference until three-fourths of the pin is in position. The high safety factor inherent in SHEAR-PROOF™ Pins makes them practical and efficient for such constant shear applications. Type C SHEAR-PROOF™ is a special pin.

High Pressure Piston and Rod Assembly
Type B Pin was used here because the half length grooves simplified the job of starting the pin into the hole. Ease of assembly was matched with sufficient locking power even when subjected to continuous, strong reciprocating forces. Type B SHEAR-PROOF™ is a special pin.
