Mishimoto MMLG-15-20LBK Aluminum Locking Lug Nuts M12x1.5 20pc Set Black 50mm

Vehicle Fitment

• Universal - fits any vehicle equipped with M12 x 1.5 wheel studs. Commonly used on Honda, Acura, Toyota, Lexus, Mitsubishi, Mazda, Hyundai, Scion, Volvo, and select Chevrolet models. Always verify compatibility with your specific wheel and wheel stud before purchase.

Fitment Notes

• Designed for vehicles with M12 x 1.5 threaded wheel studs. Not compatible with M12 x 1.25 or other thread pitches - see MMLG-125-20LBK for M12 x 1.25 applications (Subaru, Nissan, Infiniti).
• Conical (tapered) seat design fits many OEM and aftermarket wheels. Verify that your wheels use a conical seat before purchase - spherical or flat-seat wheels are not compatible.
• Not recommended for use with stock OEM wheels on most applications. Intended for aftermarket wheels compatible with the conical seat and open-ended lug nut design.
• Open-ended design: total length is 50mm. Verify that your wheel stud length is compatible with the open-ended format before purchase.
• Anodized finish care: avoid abrasive or corrosive cleaners and do not use power tools for installation or removal, as these will damage the anodized surface. Mishimoto does not warrant finish fading or tool-related damage.
• Available in black (MMLG-15-20LBK - this listing), blue (MMLG-15-20LBL), silver (MMLG-15-20LSL), red (MMLG-15-20LRD), and neochrome (MMLG-15-20LNC).

Features

• Each lug nut is machined from a single piece of 7075-T6 aircraft-grade aluminum - one of the highest-strength aluminum alloys available, with ultimate tensile strength of 74,000-78,000 psi and minimum yield strength of 63,000-69,000 psi, providing the structural integrity required for safe performance wheel applications.
• Weighing only 0.8 oz (22.68 g) per nut, the 20-piece set provides a significant unsprung weight reduction versus a full set of steel OEM lug nuts - a meaningful improvement for handling response and rotational inertia on performance builds.
• Open-ended design with a total length of 50mm accommodates extended wheel studs used in motorsport and performance applications without restricting stud length compatibility.
• Conical seat geometry fits a broad range of OEM and aftermarket wheel seat profiles, providing secure clamping force without requiring tapered washers or adapters on compatible wheels.
• Knurled end on each lug nut allows for fast hand-threading to engagement without tools - reducing installation time and the risk of cross-threading during wheel changes.
• Kit includes 4 locking lug nuts with a dedicated non-marring key socket - providing theft deterrence on all four road wheels. The non-marring socket is lined inside and out with soft plastic to protect both the wheel finish and the lug nut anodizing during installation and removal.
• Black anodized finish provides a corrosion-resistant surface layer and a bold, aggressive appearance that complements both dark and polished aftermarket wheels and suits a wide range of build themes from subtle to track-focused.
• Installation difficulty rated Easy. Backed by the Mishimoto Lifetime Warranty.

Product Description

The Mishimoto MMLG-15-20LBK is a 20-piece set of M12 x 1.5 aluminum locking lug nuts in a black anodized finish, machined from 7075-T6 aircraft-grade aluminum. The M12 x 1.5 thread pitch is the most widely used metric lug nut size in performance automotive applications, covering the majority of Honda, Acura, Toyota, Lexus, Mitsubishi, Mazda, Hyundai, and Volvo platforms - including the Mitsubishi Lancer Evolution I through X, Toyota MK3 and MK4 Supra, GR Corolla, Honda Civic, Acura Integra, Lexus IS-series, and numerous others. At 0.8 oz (22.68 g) per nut, the full set of 20 provides a substantial reduction in unsprung rotational mass compared to steel OEM lug nuts - a tangible benefit for handling response and corner entry sharpness on any performance-focused build, from a daily driven sport compact to a dedicated track car.

Each nut is machined from a single billet of 7075-T6 aluminum, delivering ultimate tensile strength of 74,000-78,000 psi and minimum yield strength of 63,000-69,000 psi - structural properties that meet the demands of performance wheel applications at the thread level. The open-ended design with a 50mm total length accommodates a wide range of stud lengths, including extended racing studs. The conical seat fits a broad range of aftermarket wheel seat profiles with no adapters required. The knurled end enables fast hand-threading to engagement before final torquing, reducing changeover time on wheels-off service or at the track. Four of the twenty nuts are locking units secured with a unique-pattern key, providing meaningful anti-theft protection on all four corners. The included non-marring socket is soft-plastic lined on both interior and exterior surfaces to protect the wheel face and the anodized nut finish during installation and removal.

The black anodized finish provides a corrosion-resistant surface that maintains its appearance across a wide range of weather and driving conditions, and complements both dark and bright aftermarket wheel finishes. These nuts are designed for use with aftermarket wheels using a conical seat - verify your wheel's seat type and the compatibility of the 50mm open-ended format with your specific wheel and stud configuration before purchase. Not recommended for most stock OEM wheels. The anodizing must be maintained with non-abrasive cleaners; power tools will damage the finish. For M12 x 1.25 applications (Subaru, Nissan, Infiniti), see the MMLG-125-20LBK. Covered by the Mishimoto Lifetime Warranty.
