These are a set of 4 Triumph Rocker Box Studs, Nuts and Lock Washers in Stainless Steel. These will fit the unit construction 350/500. These are the studs that come down through the head at the back and front of the rocker box. The Triumph part numbers for these studs are E3858.

The cycle studs and nuts have the correct 60 degree thread angle; and the correct spanner size across the flats, 4 rectangular section stainless lock washers are included.  All studs have a  slight radius on the end the same as original.

The nuts have a single sided chamfer and are machined back and front to leave a nicely machined finish, each flat of the hexagon has 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 should be assembled with copa slip (copper slip), which we also list on ebay.
