Correct wheel nuts

[Paulontour]

So yesterday I had four new tyres fitted and one of the wheel nuts sheared off. I blame the tyre centres for fitting the wheels with their air rattle guns. Anyway I thought I would replace all the wheel nuts with new ones. Can any one tell me what the correct dia and pitch of the bolts should be. Also with alloy wheels should it be alloy nuts or steel nuts.
Thanks.

As above, Bolt pack1 from Alloy wheels direct will fit. £42 for a set of 20 bolts.

If you want to go a cheaper way, eBay sellers have them, but be sure to get ones with radius head fitment and not tapered. You can pick up a set of 20 bolts for around £20 and they will be bright zinc plated.

The size needed are M12X1.5mm thread pitch, 17mm head, 12mm radius seat 39mm long.
Something like these.
