These are a set of 8 Triumph 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, 8 rectangular section stainless lock washers are included. All studs have a slight radius on the end the same as original. The Triumph part numbers for these studs are E3820 x 6 + E3819 x 2 These will fit the 350/500cc unit motors and have a BSF thread into the crankcase. The nuts are cycle.
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 side 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.
They will fit 3T, 3TA, T100, T100A, and T100ss and maybe more. Please note all stainless parts MUST be assembled with copa slip (copper slip) available from this site,
