• Identification
  In addition to the thread size and part number, we roll mark our name into the surface of every Tough Nut. This is your assurance that you are getting McGard quality and safety.
• Through-Hardened Steel Construction
  Every lug nut is through-hardened and tempered, reaching the depth of hardness needed for its unsurpassed level of safety (unlike case hardening which is only a surface treatment).
• Precise Bearing Surfaces
  McGard’s standard for concentricity of the bearing surface to the pitch diameter is 30% more precise than OEM standards. This insures even distribution of the clamp load and uniform seating of the lug nut to the wheel.
• Restricted Chemistry Steel
  We use only restricted chemistry steel for our fully machined lug nuts. This steel is made in the United States, specifically for McGard. Our special standards insure the structural integrity of each and every McGard lug nut.
• The Best Chrome Plating In the Industry
  The best in the industry. Our process includes three layers of nickel and one layer of microporous chrome. The first layer of nickel is for corrosion resistance; the second layer of nickel is for luster and the third nickel layer interacts with the microporous chrome layer to disperse nature’s corrosive action (rust).
• Precision threads
  Core integrity and precision machining provide the highest strength in the industry. All McGard locks and lug nuts meet or exceed the highest OEM proof load standards, 135,000 to 160,000 PSI.
