Silicon Bronze Cotter Pins

These high quality, marine grade silicon bronze cotter pins (also known as split pins) come in handy for all kinds of uses on a boat. From securing classic sailing yacht rigging, to locking your prop's bronze castle nut so it doesn't back off, they are always good to have around. Pick up a few of each size and be sure that you'll be able to solve those inevitable issues right out on the water. 

Our cotter pins are made from SOLID alloy 873 silicon bronze, also known as Everdur. No plated rubbish here! They are incredibly resistant to saltwater and will hold your clevis pins, props, turnbuckles, and other various fittings securely for years to come.

We're proud to say that Fair Wind Fasteners carries the largest selection of silicon bronze cotter pins in the United States, and on the web. 

Cotter pin thickness (diameter) is the thickness of the shank across both prongs, and the length is measured from the bottom of the head to the shortest prong. Please see the diagram in the photos for sizing help.
