The 600-piece zinc plated steel cotter pin assortment includes cotter pins in various sizes and comes in a compartmented plastic case for storage and organization. Each pin has one prong extended for insertion and bending, and has a chisel point end. The pins are made from steel for strength. The material is magnetic. The zinc plating offers corrosion resistance and a reflective appearance.Pins are non-threaded cylindrical fasteners that are inserted into one or more holes to fix a component's position, join components, or maintain alignment between them. Several different pin styles fit a variety of application and installation requirements. Dowel pins, for example, have a solid shaft that is often rounded or beveled at the ends. Quick-release pins have a button, handle, or ring at one end that releases retractable balls at the other end to act as a lock-and-release mechanism. Clevis pins have a head at one end and one or more cross holes at the other end that allow insertion of cotter pins to lock components in place. Cotter pins have two prongs that can be inserted into the hole of clevis pins or other fasteners and bent to secure them in place. Taper pins are tapered consistently across the body of the pin so that one end has a slightly larger diameter than the other. Spring pins are slotted or coiled to expand to fit the diameter of a hole, which should be smaller than the diameter of the pin.
