H&R 1453101KEY4 Locking wheel bolts Conical Seat F, 31 mm

Important notes for wheel screw order: Please note additional information and vehicle-specific technical notes! When using wheel spacers, the new wheel bolt must be longer by the thickness of the spacer! The current tightening torques (please note any differences between alloy wheels and steel wheels) are the vehicle manufacturer's specifications for the fastening, respectively the wheel manufacturer ones when using aftermarket wheels as well as the part approval for the wheel spacers.

Check the minimum screw-in depth of the longer wheel bolts! Please note the following minimum screw-in depths:

Thread M12x1.25 = min. 8.0 turns = approx. 10 mm load-bearing thread

Thread M12x1.5 = min. 6.5 turns = approx. 10 mm load-bearing thread

Thread M12x1.75 = min. 6.5 turns = approx. 12 mm load-bearing thread

Thread M14x1.25 = min. 9 turns = approx. 12 mm load-bearing thread

Thread M14x1.5 = min. 7.5 turns = approx. 11 mm load-bearing thread

Thread 1/2" UNF = min. 8.0 turns = approx. 11 mm load-bearing thread

A too great screw-in depth can cause damage to the axles (brake parts, ABS control discs, etc.). For this reason, after fitting the wheels, these must be turned by hand in a relieved condition in order to check that the longer wheel bolts are free to rotate inwards. For some vehicles, the critical tolerance is by 2 mm.
