Dorman - Autograde Wheel Lug Nut P/N:611-239
Help keep your wheels secured with Dorman lug nuts built as a one-piece replacement for damaged or stuck originals: the Dorman - Autograde Wheel Lug Nut 611-070. It is a direct-fit replacement for the 1990-1991 Chevrolet Blazer, with a 7/16-20 thread, dome top, 3/4 in. hex and 1-1/8 in. length.
Some factory lug nuts use a two-piece design with a thin outer veneer. Repeated use can damage that veneer, and moisture that gets underneath can make the cover bulge. A bulged nut can be difficult or impossible to remove, and freeing a stuck one usually means damaging the wheel itself. This Dorman OE FIX part is designed to match the original's fit and function. It switches to a one-piece, carbon steel design intended to keep those failures from happening again.
If you are looking for Dorman autograde lug nuts, note that this one takes a 3/4 in. socket. Tighten it to the torque value in your vehicle's service information. See the "Vehicles it fits" section for complete fitment details.
