Stainless Steel Split Pin (Split Cotter Pin) 316 Marine Grade Stainless steel split pin, some times 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 joing 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. Split pins are intended for single use only, when they are removed they should be replaced with new split pins to prevent the possibility of fracture due to fatigue damage. For areas where repeated assembly and dis-assembly is needed consider using ring pins as a preference to split pins. With regard to size selection, split pins are sized for the hole that they need to pass through, both on assembly and dis-assembly. 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.
