Forged Wheel Bolts

Lifetime Warranty

Set of Forged Replacement Wheel Bolts. Available in sets of 8, 10, 12, 16, 20, or 24 - choose using the dropdown box above.

All of our Forged bolts are made to the very highest standards. The raw materials are inspected to ensure the structural integrity of the complete bolt, and every bolt is through-hardened and tempered. The plating process includes several layers of nickel and one layer of microporous chrome producing a superior finish that looks great and also protects against rust.

This rigorous manufacturing process produces original-equipment standard bolts that come with a no quibble lifetime warranty, guaranteeing the bolts for the lifetime of your vehicle*.


Technical Specifications

  • Thread Size (T): M12x1.25
  • Thread Length (TL): 36mm
  • Overall Length (L): 62.5mm
  • Hex Size: 19mm
  • Seating: Flat
  • Finish: Zinc
  • Flat Washer

Please note that the thread size shown is made up of the following:

  • The diameter of the threaded section, measured in mm across the outer edges of the thread (e.g. "M12" refers to a 12mm diameter)
  • The thread pitch is the distance in mm between threads (e.g. if there are 8 threads within a 10mm section the pitch is "1.25", as 10 divided by 8 equals 1.25)

It is extremely important that your bolts seat properly in the holes in your wheels, in other words the profile of the head of the bolt needs to match the profile of the inside of the hole exactly. Some wheels require bolts with a 60 degree tapered seating, some need a radius seating and some need a flat seating. Please be aware that the vast majority of aftermarket wheels require a 60 degree tapered nut or bolt.


Spot The Difference

A fresh set of wheel bolts can make a surprisingly big difference to the overall appearance of your wheels. Old bolts that have become rusty, or have cracked and peeling paint, can really stand out and spoil the look of otherwise pristine alloy wheels.

Replacing them with a new set of high-quality Forged Bolts won’t just keep your wheels securely fitted and your car safe – their hard-wearing protective finish adds the perfect finishing touch. And with our lifetime warranty*, you can be confident they’re built to last.

How Are They Made?

All Forged wheel nuts and bolts are manufactured to the very highest standards. Each batch of raw material is carefully inspected to ensure complete structural integrity, and every part is through-hardened and tempered for maximum strength and durability.

To achieve a premium, long-lasting finish, the bolts are plated using multiple layers of nickel followed by a final layer of microporous chrome. This not only looks superb, but also provides excellent protection against corrosion.

This rigorous process results in bolts that meet original equipment standards - in fact, the very same bolts are used worldwide by over 20 different vehicle manufacturers.
