Overview
The Gorilla Automotive 91187SS is a pack of four 1/2 inch-20 hex lug nuts made from 304 grade stainless steel, with cold headed chrome vanadium steel seating surfaces. Lug nuts hold a wheel to its hub studs, so the thread size and seat style matter more than the body of the vehicle.
Each nut is hand polished before the plated finish is applied, and the finish is salt spray tested for over 240 hours. Check the thread and seat style against your wheel studs before ordering.
Key features
- 304 grade stainless steel body for a stainless finish
- Cold headed chrome vanadium steel seating surfaces
- Each nut hand polished before the plated finish is applied
- Plated finish salt spray tested for over 240 hours
- Hex style with 1/2 inch-20 thread, sold as a pack of four
Stainless and seat wear
Stainless steel resists rust well, but the seating surfaces decide how the nut clamps. Chrome vanadium seats hold their shape under repeated torque, which helps keep the clamping force steady. Still, a seat that is dented or flattened should be replaced, since no finish can restore a damaged seating area.
Clean stainless nuts with water and a mild cleaner, then dry them before refitting. Avoid steel wool and abrasive pads, which can leave scratches that trap grime. Grime between the seat and the wheel can cause a nut to loosen, so keep the seating areas clear before tightening.
Check the threads on each wheel stud before fitting the pack. Run each nut on by hand to confirm it starts smoothly, then tighten in a star pattern in stages. Recheck after the first few drives.
