This listing is for a 'Long Length' magneto bolt/nut - of the type that were fitted on the rear fitting of the magneto platform on SOHC Norton engines.  This type of 'wasted' extra long nut were designed this way - because then they would protrude down beyond the rear engine plates, and so be easily accesable - to allow for magneto chain adjustment.  This extra long type were fitted to all Pre-Featherbed SOHC models.  They are CNC bar turned to the original 'wasted and 'drilled' dimensions of the original, in the correct imperial Hex stainless steel.  See detail listing for more information.  Price is Each
