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.
Leitfaden zur Messung von Radmuttern / Sitzen
Überprüfen Sie den Sitz der Radmuttern auf der ('Radanlagefläche') auf ordnungsgemäßen und sicheren Sitz - Sitztypen sind nicht austauschbar.
McGard Qualitätsvergleich
McGard testete die Korrosionsbeständigkeit seiner Radmuttern im Vergleich zu vier Mitbewerbern in einem CASS-Test (copper-accelerated acetic acid-salt spray). Bei diesem Test werden die beschichteten Teile einer Salzlösung bei einer bestimmten Temperatur, einem bestimmten Druck und einer bestimmten Dauer ausgesetzt, um die Aussetzung gegenüber den Witterungsbedingungen zu simulieren (vergleichbar mit den Wetterbedingungen in Detroit). Vor jedem 22-stündigen CASS-Zyklus wurden die Radmuttern mit einem Radmutternschlüssel angebracht und entfernt, um den normalen Gebrauch zu simulieren.
