McGard Locking Wheel Nuts – Standard Size M12 x 1.5 (21156SU)

Description

Genuine McGard · Part no. 21156SU

McGard 21156SU is a set of M12 x 1.5 locking wheel nuts from the Standard (SU) range, with one key. They are for stud-fitted wheels. Owners who swap between steel winter wheels and alloys should check both, because the two types of wheel often need nuts with a different seat or length.

Good to know

• Will one set suit my steel and alloy wheels? Not always; steel and alloy wheels on the same car often take different nuts, so check both before relying on one set.
• How should I fit them? One nut per wheel, started by hand, then tightened in a criss-cross order to the handbook torque.
• What if I need to remove one without the key? A removal tool usually damages the lock beyond reuse, so a whole new set is then needed.
