These are the distinctive 9/32" x 26tpi BSC tapered locknuts as fitted to the Norton OHV/Walter Moore CS1 Flat Pad type rocker adjusters (our items 1121 and 1122 from approximately 1929-37. These have been CNC manufactured in stainless steel to exactly the same dimensions as a Norton 1930's example. Note we also sell the locknut with the actual adjuster - see Item 1121 and 1122, but as the original nuts are often chewed or come loose and fall off - we sell them on their own here.
Price is each (i.e. one locknut)
The thread on these locknuts is - 9/32" x 26tpi BSC thread - as per the original item.
This nut is CNC manufactured in stainless steel to the original Norton design - which has a slight taper on one end - which should fit into the original Norton OHV Rocker recess. The other end has a minimum chamfer. This locknut is copied from an original period Item - but unlike the original, ours are CNC manufactured from stainless steel - to prevent rusting. It should be noted that on the original 1930's nut that we coped - we noted that the depth of this nut was fractionally deeper than the original earlier 1920s ball type rocker version of the same nut. The difference is minimal though, and I suspect either type could be used if one or other type is out of stock.
See also the description listing for Item 1119 (Ball Type Adjuster and Locknut - Pair) for more background information on these items.
If these nuts are showing out of stock - then Item 1120 is a possible alternative as the depth difference of the later nut is only fractionally shallower than this type - we decided to make both types because we wanted each Rocker Adjuster/Locknut combination to be true to the original patterns we copied
