Description

DIN *4 Split Pins (Cotter Pins) are common used fasteners that hold assemblies together. Made of soft metal wire looped on itself so the two resulting tines can be inserted into a pre-drilled hole and bent to keep it in place. Cotter pins are typically made of soft metal allowing for easy installation and removal. However, this also makes them poor locking devices when strong shear forces are expected.
