Frequently asked questions

What is the GA7331 tamper proof nut set for?
The GA7331 set is four M8 security nuts with a matching key, used to fasten bolt-on equipment like roof racks, roof tents, winches, and bumpers so it can't be removed without the key. The nuts have no conventional wrench flats, so a spanner alone won't shift them.
How many nuts and keys come in the GA7331 set?
The set includes four M8 nuts and one key, enough for a typical four-point roof rack or bumper mount. For applications with more than four fixing points, order enough additional nuts to match, keeping the key handy since it's needed for removal too.
Do I need special tools to fit the GA7331 nuts?
No extra tools beyond the supplied key. The nut has no conventional wrench flats, so it threads on and off using only the key provided in the set, which keeps it secure against removal by anyone without it.
