New Racing Nut Tells You When it’s Tight

TandN Products has unveiled a NASCAR approved “Saf to GO” lug nut that tells fitters when the nut is snug to the wheel by indicating when two full threads are exposed out of the top. Developed by a NASCAR winning crew chief in partnership with a high-tech racing component manufacturer, the new product is designed to be used with any hub using 5/8-18 conventional racing piloted wheel studs. When threaded onto a stud, a coloured plastic ring on the end of the nut is shattered as the threaded portion of the stud pushes up on the ring.

Thus exposing the contrasting colour of the nut, and indicating the nut is safely snug to the wheel and has two full threads exposed. These Teflon coated lug nuts are manufactured with 4140 steel, and heat-treated to keep from rounding. The technology is said to have a patent pending.
