ECS BMW Wheel Bolts, Wheel Studs and Nuts for BMW E21 320i M10 1.8L

Clear BMW chassis

Please ensure your correct model is selected

Any time you use a wheel spacer you MUST have a longer wheel bolt or wheel stud to properly fasten the wheel to the hub. We offer extended wheel spacer bolts in silver and black finish in a variety of lengths to fit many spacer sizes. We're up to date on the different thread sizing as well - 12x1.5, 14x1.25, and 14x1.5 so we can supply wheel bolts for just about any BMW or MINI.

Add the spacer thickness to your stock bolt length and that is your ideal extended bolt length. We generally sell bolts by spacer thickness but there may be exceptions. It's always best to measure from the wheel bolt you're currently using. When we list the total length of a bolt it's from the base of the mounting seat to the tip. To be considered safe, a 12x1.5 wheel bolt needs 10mm (6.5 turns) of thread engaged; a 14x1.25 or 14x1.5 bolt needs 12mm (9.0 and 7.5 turns) of engaged thread.

These wheel locks are made in extended lengths to work with wheel spacers. This is the standard conical seat bolt in a 12x1.5 thread pitch (most BMWs up to 2012). This is a set of 4 bolts - one bolt per wheel that replaces one of your existing extended wheel bolts. The 9 point socket provides an extra layer of protection for your coveted wheels. Black zinc coating resists rust and corrosion. Choose the wheel locks to work with your wheel spacers from the list below.
