JN1 Steel Wheel Nut SpecificationThese GT50 wheel nuts are open ended (compatible with longer studs) and feature a knurled end to make installing the first few threads by hand very easy.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.
