Lug nuts/bolts have two compatibilities, one to match the lug nut/bolt thread size to the vehicle's wheel studs/hub and the other to match the lug nut/bolt style to the wheel. The compatibility tool is used to match the thread size of the lug nut/bolt to the vehicle's wheel studs/hub, it does not match the lug nut/bolt style to the wheel. Make sure you have chosen the correct style prior to placing an order, ask if you have any questions.

  • This style of lug bolt is generally used on aftermarket and some OE wheels requiring a conical seat.
  • Lug bolts will fit many vehicles requiring 12x1.5 threads.
  • The vehicle compatibility guide refers to the vehicles thread size only.
  • Please verify this is the correct style of lug bolt for your wheels before ordering, if you have any questions please ask.
  • If you plan on using the factory lug wrench check the hex size and make sure it matches.
  • Each lock set is supplied with a key number card, keep it in a safe place, in the event a replacement is required you will need it.

  1. 8 different hex key sizes
    McGard is the only manufacturer to offer 8 different key hex sizes to match the vehicle’s original equipment lug wrench. You will appreciate this important feature when you have to change a flat tire along the roadside.
  2. User friendly keys
    McGard's steel collar guides the key into the lock pattern. Simply place the key over the lock and turn until the patterns engage. The collar holds the key in alignment for easy installation and removal.
  3. Computer generated extra narrow groove key patterns
    The computer generated key designs allow for an infinite number of key patterns. The narrow groove resists the intrusion of lock removal tools into the pattern
  4. The best chrome plating in the industry
    The best in the industry. McGard's 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).
  5. Through-hardened steel construction
    McGard uses only restricted chemistry steel, made in the United States, specifically for McGard. These special standards insure the structural integrity of each and every fully machined McGard wheel lock. Every lock is through-hardened and tempered, reaching the depth of hardness needed for its unsurpassed level of security (unlike case hardening which is only a surface treatment).
  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.
  7. 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 lock to the wheel.
