Cotter Pin A2

Cotter pin A2 is made of stainless austenitic steel. It is used to secure connected parts, as well as a lock against self-loosening of bolts and nuts.

This is a metal fastener made of stainless wire, bent into various shapes:

• straight or split (spread-leg) cotter pin;
• with a T-shaped head;
• spring (hairpin) cotter pin.

Using cotter pin A2 together with a bolted connection speeds up assembly and makes it more convenient, and increases the tightening force of the threaded joint. Stainless cotter pins have the properties inherent to chromium-nickel steel: stable performance at high and low temperatures, no corrosion, non-magnetic, non-toxic.

Cotter pin A2 is used in construction, at industrial facilities, in the oil and gas production and chemical industries, and in household applications. It is especially in demand in machine building for fastening rotating assemblies. Cotter pin A2 firmly secures parts under light operating loads and ensures reliable fastening of critical structures.
