JN3 Steel Wheel Nut SpecificationThese Neo steel wheel nuts use a splined socket to give both good drive for removing/installing your wheels and added security (you need to supplied key to remove them).They have a 60deg taper as compatible with all aftermarket and OE wheels. They are made from high strength steel for safety and do not have quality/strength issues like cheaper Chinese steel nuts or require re-torquing like aluminium nuts.To ensure optimal finish never use an impact gun to tighten your bolts/nuts - always torque by hand.
