AUTOPTIM M12x1.5 Spline Lug Nuts 20-Pack Chrome Closed-End with Socket — Triple-Chrome, 60° Taper

A 20-piece set of AUTOPTIM M12x1.5 chrome closed-end spline lug nuts with a matching spline socket delivers corrosion-resistant wheel fasteners engineered for one-piece strength and a precise fit.

These lug nuts are made for drivers who want a reliable aftermarket replacement that matches common M12x1.5 wheel studs on many Honda, Toyota and Chevrolet models. Each nut is cold-forged, heat-treated and triple-chrome plated to resist rust and cracking while providing a tapered 60° seat and a 17 mm hex profile. The kit includes twenty closed-end spline nuts plus the spline socket needed to install or remove them, making it a complete swap when you change wheels or refresh worn lug hardware.

Which cars and wheels will these lug nuts fit?

These AUTOPTIM nuts are designed for wheels that accept M12 x 1.5 thread lug nuts with a 60° tapered seat and a 17 mm hex engagement. They are aftermarket replacements compatible with many model years of Honda, Toyota and Chevrolet, and other vehicles that use the same stud specifications.

• Common fit examples: 1994–2013 Chevrolet Impala, 1982–2019 Chevrolet Malibu
• Honda examples: 1998–2022 Accord, 1997–2022 CR-V, 2004–2022 Civic
• Toyota examples: 1983–2020 Camry, 1996–2013 RAV4
• Always verify your wheel bolt thread, seat angle and hex size before purchase

How do these one-piece lug nuts improve durability and safety?

The AUTOPTIM lug nuts use a one-piece construction rather than a two-piece design, which reduces the chance of separation or cracking under stress. Combined with cold forging and heat treatment, the nuts maintain thread integrity and resist deformation during repeated torqueing.

• One-piece construction minimizes mechanical weak points and potential failure modes
• Cold-forged steel and heat-treated finish increase strength and wear resistance
• Precision-cut threads ensure secure engagement with wheel studs for consistent torque

What corrosion protection and finish features are included?

The set is finished with a triple chrome plating process that improves resistance to rust and environmental wear compared with untreated steel. The closed-end style also shields the stud tip from moisture and grime, helping extend the life of both nut and stud.

• Triple chrome plating reduces oxidation and maintains appearance over time
• Closed-end design prevents contaminants from reaching the stud tip
• Recommended for drivers who live in wet or salted-road regions

What comes in the box and how do you install them?

The package includes twenty chrome closed-end spline lug nuts and one matching spline socket sized for the nut profile, providing everything needed for a full wheel lug nut replacement. Installation follows standard torque procedures for your vehicle—tighten to manufacturer-specified torque using a torque wrench to ensure safety and proper seating.

• Contents: 20 lug nuts + 1 spline socket, 17 mm hex engagement, 35 mm length
• Seat type: tapered 60° to match most OEM wheel seats
• Installation tip: torque to vehicle manufacturer specs and re-check after 50–100 miles
