These are the distinctive Norton gearbox nuts as fitted to the endplate of all upright Pre-War Norton models and pre-Featherbed Manx models.
Seven of these are used to fit the pre-war Norton gearbox covers and are very distinctive, the shoulder fitting into the recess on the cover and the head and a slightly curved head
They are also fitte at the base of Norton laydown style (pre-AMC) gearboxs, under the kickstart boss (3 are fitted here - see photograph).
These nuts are CNC manufactured by us to exactly the same dimensions as the original Norton items, except they are made in Stainless Steel - They look very pretty and will transform the look of your pre-war gearbox (particularly as it is now very difficult to get the originals Dull Nickel plated) - 7 required per gearbox. These are made to a higher level of finish than the original Norton nuts (which often had visible machining marks and a dimple in the centre of the head - see picture of original nut to see what we mean) - as well as being CNC manufactured to a fine finish - we also lightly linish and semi polish the heads of these nuts, so they really look nice when fitted to an original Norton gearbox . . . and we sell a lot of these!
Note: we also sell the gearbox studs in stainless steel (Item 0100), but most importantly - the correct type spring washer, also in stainless steel (Item 0102). It is very important to fit one of these spring washers under each nut - otherwise the hex of the nut is likely to catch and scratch the gearbox end cover - look at the amount of old Norton upright gearbox covers you can find that have suffered from this issue!
