Wheel bolt M12 x 1.5 x 21mm radius seat

Product details:
– thread: M12 x 1.5
– thread length: 21mm

How do I measure the correct length?
Measure the length of the original thread and add the thickness of the spacer to get the length you need.
Example: original thread 27mm + 15mm spacer = required thread length 42mm. If we do not stock that length, choose the next length available.

Notes:
– price is per piece (1 bolt)
