These are the drain plugs fitted into the base of the alloy fork legs on Longtype Roadholder Telescopic Forks - as fitted to most single cylinder models up to the late 1950's, and which allow the fork oil to be drained.
These items are CNC machined in stainless steel to the original thread size and tolerance, with a nice quality head and milled slot in stainless steel. Original Long roadholder fork alloy sliders and an original Norton drain plug screw were used as patterns to test the tolerance and fit of these screws when manufacturing. It should be noted that the length of thread on these screws is quite important, and there is a slight recess behind the thread - to ensure the screws lock fully against the fibre washers and do not protrude into the oil reservoir area of the slider (this is just visible in one of the accmpanyning photographs - looking down the internal length of the slider - the hole with thread cut can just be seen, but the head of the screw does not protrude past the wall of the thread bore).
Each pair comes with 4 of our high quality red fibre washers - 2 per screw. These washers are from a high quality manufacturer and fitting two seeems to give just the right level of grip. Price is for a pair of screws and 4 fibre washers.
Note: It is important to note that these screws have 1/4" x 26tpi thread - as was originally fitted to early Norton (Long) Roadholder Forks, as fitted to most Single Cylinder Norton models to the late 1950's. At some point in later years (possibly the 1960's) - Norton's changed the thread of the drain plugs - I have heard to UNF, but rumours that other threads may have been used. Please satisfy yourself that your alloy sliders require this type of thread before fitting.
