I want to get locking lug nuts for my HW276 trailer to go with wheel boot/locks, so it takes more time and effort to steal the thing than just popping off the wheel or something.
1. What size/type of lug nuts do I need (or where can I find out)?
2. Anyone have any recommendations for brand/type?
I would guess you have the same thread and size as I do on my 228 BH; 1.2" x 20. I purchase a set of McGard 24010 Cone Seat - Under Hub Cap Wheel Locks If yours lug nuts are not under a hub, you can get the standard wheel locks from McGard.
