Split Cotter Pins Stainless Steel Marine Grade

Stainless Steel Split Pin (Split Cotter Pin) 316 Marine Grade Stainless steel split pin, sometimes known as split cotter pin(s) for boating and sailing and general marine use. Stainless steel split pins are often used for securing threads such as turnbuckles or rigging screws and trailer wheel bearing nuts.

Use our split pin size selection chart (in accordance with the standard DIN 94) to make sure your choose the right split pin for the job. Split pins are sometimes know as split cotter pins, and have a number of uses in and around the boat including the securing of threaded joints such as turnbuckles or rigging screws, and securing pivot pins such as cotter pins used in sailing pulley blocks.

The stainless steel split pin is pushed through the securing hole (after the joint has been set or tightened to the right level) and then the legs of the split pin are bent outwards to keep it in place. When using split pins in areas near sails, such as in turnbuckles, or where people may go past please beware of the ends of the split pin which can cause damage. In these places it may be preferable to use marine grade ring pins instead.

This means that the diameter of the new split pin is significantly smaller than its hole to allow it to be pulled out, even after the bent ends of the split pin have been straightened out with the aid of a screwdriver and pliers, they are never quite straight and the under-size of the split pin compared to the hole allows for an easier removal than if the split pin were a more exact match for the hole.
