These are a set of 9 Triumph 650 Pre Unit Engine Plate Studs, Nuts and Lock Washers in Stainless Steel. They are supplied together with 18 stainless 26 tpi cycle nuts which are the correct 60 degree thread angle; and the correct spanner size across the flats, 18 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. These give you the 3 front studs, the front stud that also holds the exhaust brackets, the lower centre engine plate stud, the 3 rear crankcase studs to engine plates and finally the 2 top rear engine plate studs.
The set consists of 4 off F839, 2 off F1711, 1 off F3665 and 2 of F4682,
these are the original Triumph part numbers for the studs.
They will fit all pre unit DUPLEX models. 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).
