Show original supplier description
The Gorilla Automotive GORILLA-91128HT is a heat-treated acorn bulge lug nut designed to provide a secure and durable fastening solution for your wheels. With a chrome-plated finish, this lug nut combines corrosion resistance with a polished appearance. Its closed-end design and conical seat type ensure a proper fit and maximum contact with the wheel surface. The M12-1.25MM thread pitch and 13/16" (21mm) hex size are key specifications for ensuring compatibility with specific wheel applications. The overall length of 1.4 inches further details its physical dimensions. Gorilla Automotive specifically designs these lug nuts for original equipment factory aluminum wheels. It is important to note that they may not fit aftermarket or factory steel wheels. Customers are advised to confirm fitment with their specific wheel type before purchase, as the company cannot guarantee fitment without vehicle selection.
