Gorilla Automotive 61137 in our Lug Nuts Deptartment

The Gorilla Automotive 61137 Lifetime Lug Nuts deliver professional-grade wheel fastening performance in a chrome-plated, closed-end acorn bulge design. Engineered with a 12mm x 1.50 right-hand thread and a 60-degree conical (tapered) bulge seat, these lug nuts are suitable for both steel and aluminum wheels. The closed-end cap protects threads from corrosion and road debris, while the 6-point hex head provides a secure, slip-resistant socket fit.

Built to outlast standard OEM hardware, Gorilla Lifetime Lug Nuts are cold-forged and heat-treated, achieving a Rockwell C35–40 hardness rating for exceptional strength and durability. A triple nickel chrome plating process provides a brilliant finish and surpasses 240-hour salt spray testing — backed by Gorilla's lifetime rust-free warranty for the original purchaser.
