Security and Great Looks.

McGard wheel locks & lug nuts for boat trailers are made to the same proven quality as our automotive line of products. For steel or alloy wheels, simply replace one of the lug nuts with a McGard wheel lock. Our wheel locks and matching lug nuts are machined from high quality steel, through-hardened and then triple-nickel chrome plated for durability and long-lasting beauty.
Every McGard Lug Nut is guaranteed for life not to rust, chip, or peel!
