The 300-piece spring steel slotted spring pin assortment with plain finish includes spring pins in various sizes and comes in a compartmented plastic case for storage and organization. Each pin has a chamfered end for insertion. The pins are made from spring steel, which offers flexibility and a balance of strength and toughness. The material is magnetic. 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.
