OG Secure | M8 (8mm) Anti-Theft Security Nut Set - Stainless Steel | Tamper Proof Shear Nuts for Roof Tent, Winch, Light Bar, E-Bike | For 8mm Bolts

Purchased before a big European roadtrip, these work perfectly to provide an additional layer of security for a Tentbox (Lite 2.0 in our case).They're not going to totally prevent a determined thief from stealing something like a Tentbox but it might put them off/delay them for at least a few minutes.

All good no issues.

At first I thought the tool didn’t fit the nuts but soon realised you just rotate the nut until it matches the bolts!Great product, really easy to use and has given me peace of mind adding some extra security to the roof tent.

Perfect, exactly as described

Bought to ensure my tent box was secure. Great item. Does the job. Very happy with them.

There are only 4, so if you use 1 on each bracket of the roof tent then all you have to do is undo the non-security nut and this comes loose enough to just spin off by hand! Absolutely ridiculous not to supply 8 at this price

I purchased these to replace four of the nuts on my roof top tent on the car. It’s never going to stop someone who really wants to steal it but it will deter and slow them down. Well made and work very well. I recommend getting a 17mm ratchet spanner if you’re planning on using it for the same job!

Really good does the job
