M12 x 1.25, Lock Bolt, 60° Taper, 17/19 Hex,Chrome

M12 x 1.25, Lock Bolt, 60° Taper, 17/19 Hex

A security wheel bolt with M12 × 1.25 thread and 60° conical seat, providing coded anti-theft protection on vehicles that use finer-pitch M12 bolts. Replacing one standard bolt per wheel with this lock bolt means only the supplied coded key can remove it; the outer body provides no conventional tool grip.

Available in black or chrome. The dual 17/19mm key is compatible with standard torque wrenches and socket bars, making installation straightforward.

Thread Pitch Applications

M12 × 1.25 (fine thread) and M12 × 1.5 (coarse thread) are not interchangeable. Forcing the wrong pitch into a hub will cross-thread and damage the mounting. The 1.25mm pitch is more common on Japanese and Korean vehicle platforms; the 1.5mm pitch is more common on European platforms. If you're unsure, measure the thread pitch on your existing bolts or check your vehicle handbook before ordering.
