Stainless Steel Cotter Pin

A stainless steel cotter pin is a metal fastener in the shape of a rod. The pin’s body is bent in half, forming a loop at the bend point.

The stainless cotter pin is used to secure lightly loaded elements, as well as a locking element for nuts — to prevent them from spontaneously unscrewing.

The most widespread types are cotter pins of the classic rod design, as well as the spring design.

Applications

Stainless steel cotter pins are used where connections need to be secured against spontaneous separation through unscrewing. As a rule, this is in instrument making and mechanical engineering. They are also used in everyday life.

Increased strength characteristics at the attachment point cannot be achieved using a cotter pin. If the joint is operated under intensive mechanical loads, a different type of additional fastening should be used instead of a cotter pin.

Installing a cotter pin is simple. Slots are required on the upper part of the nut used for fastening. The cotter pin’s rod is inserted into the slot, then its ends are bent over. The cotter pin is a single-use product; reuse is not possible.

Features

The material used to make cotter pins is mild steel (to facilitate installation with bending) with alloying additives. Cotter pins are manufactured to GOST and DIN standards.

The products are practically not subject to corrosion and are protected against temperature and chemical effects of the environment.
