These are a set of 8 Triumph Unit Construction 350/500 Engine Plate Studs, Nuts and Lock Washers in Stainless Steel. The set consists of 1 off F2825, 2 off E3695, 1 off F3665, 1 off E3812 and 3 off E3804, these are the original Triumph part numbers for the studs. Obviously this set includes the nuts and lock washers. They all 350/500 Unit Construction twins. If you need studs for another model give us a ring we will be able to help. These are supplied together with 16 stainless 26 tpi cycle nuts which are the correct 60 degree thread angle; and the correct Whitworth spanner size, 16 rectangular section stainless lock washers are also included. All studs have a slight radius on the end the same as original. The radius is left as a machined finish so that you can either polish it to a mirror finish or sand blast it for a cadmium look. This set give's you all the studs needed to fix the engine plates to the frame and crankcases.

The nuts have a single sided chamfer and are machined back and front to leave a nicely machined finish, each flat of the nuts have been linished to leave a bright finish rather than the dull finish normally found on nuts turned from hex bar.

Please note all stainless parts MUST be assembled with copa slip (copper slip), which we also list on ebay.
