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 E672, the studs Whitworth/Cycle threads are 1-5/8" long. These will fit the 650cc unit engines up to 1968 and all pre unit 650 motors. The nuts supplied are 4 off 0.600" A/F and 4 off 0.520" A/F, same as the originals.
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 we also list on ebay.
