BONOSS extended bolts have higher grade and better performance than original bolts, so BONOSS extended bolt can withstand greater torque. Considering the different rims and thread pitch, we suggest to use the same torque that recommended by the car manufacturer.
Generally torque is shown as below:
M12x1.25: 113NM (83.3 Ft-tb)
M12x1.50: 113NM (83.3 Ft-tb)
M14x1.25: 140NM (103.5 Ft-tb)
M14x1.50: 140NM (103.5 Ft-tb)
Here are some tips of Safety Guidelines
(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
