Description
Wheel hub fasteners demand absolute precision—any movement under load compromises alignment and creates safety hazards. This PEM lock washer tanged design prevents the bolt from backing out or the washer from sinking into softer hub materials, maintaining consistent clamping force through heat cycles and vibration. If you’re running a Grand National wheel hub, this is essential hardware for reliable, drift-free wheel mounting.
