Locking nuts for driving lights?

Hi Rowen,

I had a set of locknuts that needed a special socket to remove it. The nut was like dome shaped with pins holes where the matching socket would fit in. They work fine IF the spotlight hole is recessed a bit. By that I mean if a set of pliars can get a good grip on the nut then you can undo it easy enough. But if you have to reach up to get to the nut (ie. need a small extension bar on the socket) then they work very well.

I have had mine for many years though, bought them from Marlows (now Supercheap auto parts), not sure if they still stock them. But would have thought that ARB or OppositeLock, TJM etc... would all stock them (but porbably wrong!!!)

Cheers

ARB sell them, check the web site.

Hi Rowan I have spotlights on my car. I drilled a hole through the bolt just below the nut and put a small padlock on. Dont loose the keys though Ray

I found Coventry Fasteners stock a range of security fasteners from 'Endeavour' they have all sorts of tamper proof bolts / nuts and screws. The best ones i found for driving lights were a cone shaped blank that fits over your existing bolt or nut. and leaves a smooth tapered surface that you can't get on to with vice grips etc. All you do is adjust your lights, do up all the bolts nice and tight, and drive these over the bolt heads etc. Yeah you need a cold chishel or similar to get em off at home . BUT so does any scumbag !! The problem with most of the pin drive nuts etc. is that you are limited in the torque you can apply to the fixture..

With my lightforce 170's, I put longer bolts in then tack welded an extra nut on the end of the bolt. This allows me to still adjust the lights using the inner nut. So far so good.
