McGard Tough Nuts are designed to last for life. No chipping, peeling or rusting - guaranteed to keep on shining for years. Their Tough Nuts are manufactured in the U.S.A. to meet the highest O.E.M. standards for safety and durability. They’re triple-nickel chrome plated for lasting beauty using their own in-house plating technology. Every one is backed by a written lifetime guarantee.
Features & Benefits:
1
Identification: In addition to the thread size and part number, McGard roll marks their name into the surface of every Tough Nut. This is your assurance that you are getting McGard quality and safety.
2
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).
3
Precise Bearing Surfaces:
McGard’s standard for concentricity of the bearing surface to the pitch diameter is 30% more precise than OEM standards. This ensures even distribution of the clamp load and uniform seating of the lug nut to the wheel.
4
Restricted Chemistry Steel:
McGard uses only restricted chemistry steel for their fully machined lug nuts. This steel is made specifically for McGard. Their special standards ensure the structural integrity of each and every McGard lug nut.
5
The Best Chrome Plating In the Industry:
Their 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).
6
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.
Lug Nut Measurement / Seat Guide
Verify Lug Nut to Wheel mating surface ('Seat') for proper and safe fit - seat styles are not interchangeable.
McGard Quality Comparison
McGard tested the corrosion resistance of their lug nuts against four competitors in a CASS (copper-accelerated acetic acid-salt spray). This test involves subjecting plated parts to a salt solution at a specific temperature, pressure and duration to mimic exposure to the elements (comparable to Detroit weather conditions). Before each 22 hour CASS cycle the lug nuts were installed and removed using a lug wrench to simulate normal use.
