Make a bolt for good practice

Philip Brodey, a specialist in torque at Norbar Torque Tools, commented: “Wheel nut movement indicators are an excellent warning system to visually alert a driver, transport manager or mechanic that there is a potential problem with the wheel nuts.  Equally, locking devices can serve a purpose in helping to retain the initially applied torque.

“However, the indicators and locking devices are not a substitute for good bolting practice which includes ensuring that the threads are undamaged, clean and free from rust and paint. Vehicle manufacturers’ recommendations for thread lubrication should be strictly adhered to and the correct torque should be applied using a calibrated torque tool.”
