Cotter Pins
Cotter pins are double bodied pin formed from half-round wire, a loop at one end of which provides a head. The finished part has one end of the wire extending beyond the other end, with a chiseled point. Used to anchor various assemblies by insertion into a drilled hole of a shaft or pin and spreading the points to hold the assembly in position. When used with castle or slotted nuts, it becomes a safety locking device.
Dowel Pins
Dowel Pins are solid headless straight pins with a closely controlled diameter. Applications include a wide variety of uses, including as a plug gage, hinge or shaft. Precise tolerances of dowel pins make them excellent for achieving proper alignment of parts in high-speed assemblies, or as roller bearings in bus/truck wheel housings.
Slotted Spring Pins
Sometimes referred to as Roll Pins, slotted Spring pins are hollow, headless pins, slit longitudinally, having controlled length with chamfered ends, formed to a diameter somewhat greater than that of the hole into which it is to be assembled.Slotted Spring Pins Will hold their position in an assembly by a predetermined spring tension. Spring pins are economical because they can simplify product design by replacing more expensive fasteners such as taper pins, set screws and straight pins. Stainless spring pins are commonly used in electronics and food industries.
