  • McGard locking wheel bolts Product Description

    The McGard locking wheel bolts secure your alloy wheels to your car and their two part manufacture makes them impossible to remove with standard tools.

    They are made up of 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 lustre and the third nickel layer interacts with the microporous chrome layer to disperse rust. Every lock is through hardened and tempered, reaching the depth of hardness needed for its unsurpassed level of security.

    The rotating ring on the bolt / nut head of the SL versions offers the highest anti-theft protection.

    Rated 5 out of 5 by from Great OEM product Fits like a charm and didn't have to pay 20 quid extra to BMW for exactly same product. Taking off old ones was bit of brute force issue but all sorted and really happy.

    Rated 5 out of 5 by from Great buy The locking wheel nuts are far cheaper than the BMW ones and are great quality. Ordering could not have been easier, just entered my car registration to get the right size. They were available at my local Halfords store the next day. Halfords beat the competition by a mile with brilliant all round service, ease of ordering the right items and a quality product.

    Rated 5 out of 5 by from Easy to use, great quality What I really like about these bolts apart from the advertised secuirty is the tool fits really snuggly over the bolt providing a secure fit. I bought them to replace a set of bolts fitted when the car was new where this was not the case and where the tool had cracked using the wrench in the boot. I wasn't prepared to pay dealer prices for a replacement tool or bolts as these cost just marginally more than a replacement tool. These bolts look better quality and hopefully will avoid problems down the road when I really need to change a wheel.

    Rated 5 out of 5 by from Good quality & security I chose these items over others because the locking grooves are on the inside of the bolt. Most cheaper brands have the lock around the outside, which would be easy to get around with a good grip wrench. Easy to install, just don't misplace the key!!

    Rated 5 out of 5 by from High strength and build quality. As I'd recently replaced all of my regular bolts with new shiny chrome ones I needed to replace the locking bolts too. Have used McGard products before and are definitely one of the best brands out there. Each set has a unique shape which only fits the key supplied in the box. If that wasn't enough there's also a sleeve on the outer rim which will simply spin around instead of the bolt being turned. Very high quality, durable, easy to swap over and look nice too. Definitely worth paying a little bit more for the added security, especially if you've just bought a new set of alloy wheels.

    Rated 5 out of 5 by from Very good these Well as you can guess i purchased these for a set of aftermarket wheels, as the little oiks around my area are like Magpies when it comes to something shiny. So i got them to protect my pride and joy from being the subject of their abusive ways. In all honesty they are really good and i am soo pleased with 1. How they look and 2. how easy they were to fit. Granted the sleeve for the nut was a bit tight around the wheel but thats only my experience. I would not hesitate to get another one but hopefully i will never have to as these fit soo well and in all honesty fit better than standard nuts. All in all good purchase.

Once you've sent us your old item we'll check it over, and then refund you the full surcharge as long as everything is ok.

Before you return your old unit please make sure it's in re-serviceable condition. So if you're returning caliper casings, you'll need to double check they aren't badly damaged or broken. If the part you've sent is found to be unserviceable, we reserve the right not to refund the surcharge.
