McMaster 90026A107 18-8 Stainless Steel Strong-Hold Wire-Snap Cotter Pin 1/8" Diameter, 2" Usable Length

Disassemble components frequently without losing tension in the pin. The coil preserves holding strength, so you can reuse these pins over and over. They also offer more security than hairpins and standard wire-snap pins. Also known as safety pins, pinch firmly to open and close.

18-8 Stainless Steel—The choice for wet and outdoor environments, these pins resist rusting. They are strong enough to join most components but won't withstand extreme stress and vibration as well as steel.
