Do you know those wheel locks on expensive cars that have that clover-leaf pattern? These are the same locks for your trailer wheels!
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 boat trailer wheel locks and matching lug nuts are machined from high-quality steel, through-hardened and then triple-nickel chrome plated for durability, security, and long-lasting beauty.
Every McGard Lug Nut is guaranteed for life not to rust, chip, or peel!
Note: Most O.E.M. trailer wheels use 1/2″-20 cone seat lug nuts & locks. Check with trailer manufacturer for proper thread size & seating type.
Protects against theft 24/7, you don't have to remove it to use your trailer. Install it & forget it!
