12-Pack Stainless Steel Cotter Pins

This pack contains twelve 18-8 stainless steel cotter pins measuring 5/32 inch by 1-1/2 inches. They are designed to secure metal assemblies by inserting the split pin and bending the two tines. The corrosion-resistant material suits automotive, marine and general mechanical fastening tasks.

Simple Hand Installation

Install by pushing the pin through the aligned hole until the head seats, then bend both tines outward with pliers or a screwdriver. The split design locks the pin in place under vibration. A common issue is bending a tine too sharply, which can weaken the metal and cause it to snap during service.

Limited to Drilled Hole Alignment

These pins require a pre-drilled cross hole in the bolt or shaft that matches the 5/32 inch diameter. They cannot clamp parts together or pull a joint tight; they only prevent a nut or clevis from rotating off. Applications needing adjustable tension or blind-side access will need a different fastener type.
