FEATURES OF THE DISC-LOCK SAFETY WHEEL NUT
The nut has been strengthened considerably to overcome the problems caused by air-gun abuse. Though it should be noted that while the Disc-Lock Safety Wheel Nut can now withstand such abuse, the same cannot be said of the stud. This could experience untold damage in particular stretching of the stud if the wheel nut is severely over torqued.
Better socket engagement
The height of the middle hexagon-flanged washer (see left) has been increased to give better socket engagement.
New environmentally-friendly coating
The Disc-Lock Safety Wheel Nut is now coated with a new, environmentally-friendly, anti-corrosion protection, GEOMET ® which is chrome free, ensuring it is compliant with European Union Directive 2002/85/EC (Restriction of Hazardous Substances). This new coating has passed a 720 hours salt spray test.
