Description
The Mishimoto Aluminum Locking Lug Nuts (MMLG-1220-23LBK) are a black-finished, 1/2-in x 20 lug nut kit machined from a single piece of 7075-T6 aircraft-quality aluminum, built to stand out among wheel and tire accessories while shaving real weight off every corner of your car. Each nut tips the scale at just 0.8 oz (22.68 g), and the kit arrives complete with a matched non-marring socket and key so installation stays scratch-free from day one.
Beyond good looks, this Mishimoto tire and wheel accessory kit is engineered for security and durability. The open-ended, 50 mm design pairs a conical seat with a knurled end for fast, confident installation, while the locking hardware helps deter wheel theft on stock and aftermarket wheels alike. Whether you’re comparing wheel and tire accessories at a specialty shop or searching for tire and wheel accessory providers for everyday driving and ride comfort, this Performance-grade aluminum lug nut set gives daily drivers a lightweight upgrade backed by the Mishimoto name.
Vehicle Applications
This lug nut kit is designed to fit any vehicle equipped with 1/2-in x 20 wheel studs, using an SAE 1/2″-20 UNF thread with clockwise (right-hand) thread direction and a 19mm hex size. Because compatibility is based on wheel stud thread size rather than a specific make or model, this Mishimoto locking lug nut set works across a wide range of vehicles that share this common stud specification.
