How to use

Select the appropriate 25 mm bit for the fastener type, insert the bit into the magnetic quick-release holder until it locks, then engage the holder in a compatible 1/4" (6.3 mm) drive of a screwdriver or power driver. Apply steady torque and replace bits by releasing the holder mechanism or pulling the bit from the magnetic socket when work is finished.

Usage recommendations

Use the ZOT Torsion bits for operations involving higher torque peaks to reduce risk of bit breakage. Match TORX® Tamper Resistant and hollow hex (TR) sizes exactly to the fastener to avoid cam‑out. Store the set in its plastic case to keep bits organized and protected.
