Pit Stopper Anti Theft Screws - M5, M6, or M8

Can be used on any bicycle component fastened with hex bolts.

The device itself is a small stainless steel cone with an internal thread that is mounted inside the hex socket of a bolt.
This blocks access to standard Allen keys and is impossible to remove with pliers. The only way to remove a bolt with a Pitstopper installed is by driving the included special screw into the hex socket using a Phillips screwdriver until the Pitstopper comes loose. The PIT screw has a unique thread.

Pit Stoppers fit the standard ISO/DIN standardized bolt heads. They are 2.8mm high.
Select the option compatible with the following sizes of standard hexagon socket heads:

• M5 (wrench size = 4mm)
• M6 (wrench size = 5mm)
• M8 (wrench size = 6 mm)

Contains:
2 x Stainless steel Pit Stopper with internal thread, 1 x Removal screw.
