These are a set of 9 Norton Dominator Cylinder Barrel Studs, Nuts and Lock Washers in Stainless Steel. The cycle studs and nuts have the correct 60 degree thread angle; and the correct spanner size across the flats, 9 rectangular section stainless lock washers are included. All studs have a slight radius on the end the same as original. These will fit the 500, 600 and 650cc motors.
There is some confusion in the Norton parts books as to the parts numbers for these but some of the numbers are D12/2L, D12/2S, D12/3L and D12/3S The studs have slightly domed ends which can easily be polished to look great as they slightly protrude through the nuts. The nuts have a single sided chamfer and are machined back and front to leave a nicely machined finish, each hexagon side of the nuts have been hand finished to leave a bright surface rather than the dull finish normally found on hex bar. All nuts are semi polished so they can easily be polished to a mirror finish or bead blasted to give that original cadmium look.
Please note all stainless parts MUST be assembled with copa slip (copper slip), which is also available on this site.
