Leaf Spring Mounting Bolts

Below is a selection of both leaf spring mounting bolts. You will see 1/2 Trailer Leaf Spring Bolts used on Boat Trailers more commonly than the 9/16. They are typically the 1/2 inch by 3 1/2 inch Leaf Spring Bolts. However, in some cases boat trailers were designed to use 9/16 inch diameter spring bolts, but it's more common to see 9/16 Spring Bolts used on Utility Trailers and other Land Trailers. We have both available for you in zinc plated and stainless steel. Check the diameter and length bolt you require to ensure proper fit.
