The cotter pin prevents the nut from backing off, making it safer for applications involving vibration (like engines or towing) or where the shackle might rub against surfaces.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How do I measure the correct size?\u003c\/strong\u003e\u003cbr\u003eA: Check the \"B (Pin\/Bolt)\" column in the table. This is the part that must pass through your chain link or anchor hole.
