While the 19 Hex is unique, sometimes you need that extra bit of security to ensure you wheels stay on your car at all times. Wheel Mate Monster Lug Lock Set ensures that your wheels are secure while matching the good looks and quality of the Monster Lug. Made of the same Cold Forged Chrome Vanadium, the Lock Set is OEM tough and race car proven, as it was derived by racing. The oversized 60 degree tapered seat ensures better contact on the wheel and the top knurl makes installation easier. The Lock Set is open-ended to accommodate extended wheel studs, but can be topped off with the Monster Lug Closed End Caps on OEM length studs. Available in multiple colors and in 14×1.5 and 1/2 inch thread pitches, the Monster Lug Lock Set will keep your wheels secure on your Hotrod, Pony Car, or Modern Muscle car!
