General description A pair of specially shaped air hammer punches designed to easily release and stake crush type axle nuts commonly found on both 2 and 4 wheel drive vehicles. This set reduces the chance of causing damage to the axle shaft and threads. Technical specifications Length: 178 mm Shank: 10 mm Material: SCM440 alloy steel Compatibility and accessories Designed for use with an air hammer, such as Laser Air Hammer, Part No. 6031 (or similar). Usage The kit includes a removal punch with a curved release tip to disengage the stake (crimp) and a flat bladed nut punch to reset the stake once the nut has been refitted to the axle. The release tip has a curved profile for easy access to the stake, allowing full disengagement of the crimp without damaging the axle shaft or thread. The flat stake punch is used to set the nut, preventing it from loosening. Applications include wheel bearings, prop-shaft, and drive flange stake nuts across many makes.
