ISR Performance Steel 50mm Open Ended Lug Nuts M12x1.50 - Neo Chrome

The ISR Performance Open-Ended Lug Nuts are 50mm-long steel tuner-style lugs in M12 x 1.50 thread pitch and neo chrome finish. 60-degree tapered seating fits aftermarket wheels with the standard tuner-style lug seat. Set of 20 includes a lug socket adapter, enough for a full set of wheels on most vehicles.

What It Does

Tuner-style open-ended lug nuts have a smaller diameter than OEM lugs, which clears the smaller lug pockets on most aftermarket wheels (factory lugs often won't seat correctly in deeper-set aftermarket wheel pockets). The 50mm length accommodates wheel adapters, spacers, and thicker-mounting-face wheels without bottoming out the threads. Open-ended design also lets you run extended studs without contacting the back of the lug, which matters if you've upgraded to longer ARP-style studs.

Neo chrome finish has a multi-color iridescent appearance that shifts between purple, blue, green, and gold depending on lighting. Loud, distinctive, and a popular pick on builds chasing visual contrast against a darker wheel or hub.

Fitment

Thread pitch: M12 x 1.50. Common on Toyota, Honda, Mazda, Mitsubishi, Lexus, and many Korean platforms. Verify your specific vehicle's thread pitch before ordering. Confusing M12 x 1.50 and M12 x 1.25 is the #1 lug nut mistake.

Lug seat: 60-degree tapered (tuner style). Will NOT work on wheels with ball seat, mag seat, or shank-style lug seats.
