A radical new innovation from PitLock, these tapered plugs are inserted into the head of the bolt, and prevent anyone from removing them.

Using the included extraction screw, the pit stoppers can be removed for access to the bolt, and reused again.

*NOTE: Allen key bolts use a size smaller wrench size to tighten/loosen than the bolt thread size, eg an M6 bolt uses a 5mm allen key and a M5 bolt uses a 4mm allen key. Make sure you are buying the right size for your bolt head, and be sure to double check with us if you're not sure. Returns due to wrong sizing will be subject to a restocking fee.
