McGard Locking Wheel Bolts – Standard Size M12 x 1.25 (27170SU)

Description

Genuine McGard · Part no. 27170SU

McGard 27170SU is a four-bolt locking set with one key, made with an M12 x 1.25 thread for cars whose wheels are held on by bolts rather than studs and nuts. Fitting takes a few minutes per wheel: one standard bolt comes out and a locking bolt goes in its place, tightened to the car's own figure.

Good to know

• How do I fit them? With the car on the ground, swap one bolt per wheel, start each locking bolt by hand, then tighten in a criss-cross order to the torque figure in the handbook.
• Can I use my impact gun? No. Locking wheel bolts should be tightened with a torque wrench to the car's figure, never with an air gun, which can damage the lock and the key.
• Do I need to check them later? Yes. Go round with the torque wrench again after the first 50 miles or so, as with any wheel that has been off.

Which one?

McGard also makes M12 x 1.25 Standard sets as 27169SU and 27216SU, with different seats or lengths; check yours against the old bolt.
