ISR Performance Steel 50mm Open Ended Lug Nuts M12x1.25 - Black

Our steel 50mm open-ended lug nuts in M12x1.25 thread, black finish. Set of 20 with a matching lug socket adapter. Steel construction, 60-degree tuner-style seat, built for wheels that actually need to stay on under hard driving.

What It Does

Replaces your factory lug nuts with a tuner-style steel set in 50mm length. The open-ended design works with extended wheel studs, which matters if you're running a thicker wheel, spacers, or any setup where standard closed-end lugs would bottom out before clamping the wheel. Steel keeps strength up where aluminum tuner nuts can fail under repeated heat cycling. The included lug socket adapter is the only tool you need.

Fitment

M12x1.25 thread, which fits most Nissan, Toyota, Mazda, Subaru, and Mitsubishi applications. Open-ended design works with extended studs. 60-degree tuner-style seat, so confirm your wheels use 60-degree (tapered/conical) seats before ordering. Not compatible with ball-seat or flat-seat wheels.
