Standard installation is the basis of driving safety. The minimum number of turns and the locking torque are important parameters for installation. Since the BONOSS lug nut has the same grade or performance as the original nut, the BONOSS lug nut can withstand greater tightening torque. However, considering different wheel hubs and original thread, we recommend using the minimum number of turns and torque recommended by the original car for locking. Generally, the minimum number of turns and the locking torque for different threads are as follows:
(Minimum number of turns for wheel bolts / nuts):
M12 x 1.25 = 8.0 turns = approx. 10 mm of load bearing shaft length
M12 x 1.50 = 6.5 turns = approx. 10 mm of load bearing shaft length
M12 x 1.75 = 6.5 turns = approx. 12 mm of load bearing shaft length
M14 x 1.25 = 9.0 turns = approx. 12mm of load bearing shaft length
M14 x 1.50 = 7.5 turns = approx. 12 mm of load bearing shaft length
1/2″ UNF = 8.0 turns = approx. 11 mm of load bearing shaft length
Noted: Forged aluminum alloy lug nuts are recommended more tightening number of turns to ensure load safety.
