I stock most of the popular thread sizes of press-in wheel studs in standard & extra long for race & thick-centred alloy wheels. I also carry a limited range of specific wheel studs for US vehicle OEM applications.
Various studs in 3/8", 7/16", 1/2", 12mm & 14mm threads are available in different lengths to suit different applications. In all cases the length measurement is as shown in the diagram below, from under the head to the tip of the stud. In all cases, the critical measurement is the diameter of the spline section (where it passes through the hub). Where there is no direct replacement with the identical spline diameter, it will be neccessary to utilise the next size up stud & ream your hubs to suit.
Please note that there are many more variations in wheel studs sizes than there are with wheel nuts.
Stop Press: Just arrived are Currie Enterprises screw-in wheel studs. Unlike conventional press-in studs, these screw in from the back of the hub & were primarily used by racecars, although several aftermarket hub assemblies now use them. At present I only have 1/2" x 20 unf thread in 2" (50mm) & 3" (76mm) lengths. They come with a special hardened washer & have a 19mm hex head that is only 3/16" thick, to allow room behind the hub to clear brake calipers etc.
Prices range from £2.50 ea (incl. VAT).
P & P extra.
I can also supply conversion studs, which will convert threaded hubs to stud & nut type, both UK & US sourced ones (for the hard to find 1/2" unf). Note that the overall length includes a section that screws into the hubs & also a blank section before the nut section (varies, ask for specific details). Please allow for this when selecting your desired length.
These are USA sourced studs.
I only stock some of the above studs (sourced from the USA) as they are the only source of imperial thread studs. These studs have a hex drive (allen key) system to enable them to be fitted more easily, none of the UK sourced ones have this facility.
I do stock the last one in the above list, that converts 14mm threaded hubs (VW etc) to 12mm studs to enable specific wheel nuts to be used to fit certain types of wheels, that would otherwise be impossible. This specifically applies to Wolfrace slot mags where the correct wheel bolts are no longer manufactured & this is the only way to fit them to early VW hubs.
