I am waiting to secure my winch to its bumper as in SA they are a target to sticky fingers. I had wondered what the best way of doing this might be. I want to be able to remove the winch if need be to do repairs and maintenance etc so can’t use those bolts that have a head that breaks off when it reaches a certain torque and you only seem to get security nuts rather than bolts.
I had thought about welding the bolt in place onto the winch and then just using a security nut but am not sure if the winch casing is not cast in which case this will not work. I then thought that since the bolts are only there to hold the winch in its place and are not used to pull against as the winch is mounted to the face of the bumper how about using some form of security wheel nut that has a key. I can’t seem to find out what wheel nuts are rated at and wanted to ask. Would they be your std 8.8?
You can get these in the US but can’t seem to find anything like them in the UK.

[h=4]The winch lock bolt is a custom 3/8-16 precision security bolt made from 1045 carbon alloy steel heat treated to Grade 5 yield strength. The key patterned head bolt is proprietary and the matching key is not available at your local retail hardware store. The winch lock bolt cannot be removed with ordinary screw drivers, pliers, or commonly sold security bits. Simply substitute one of your winch mounting bolts with the “Winch Lock” bolt and your winch is protected – simple![/h] Fits all winches with standard 3/8 -16 mounting hardware.
