Norton Gearbox - Large Left Hand Gearbox Sprocket Nut

Distinctive large hexagon nut that retains gearbox rear sprocket to the large sleeve gear, using Left Hand thread.  Price is Each

As always, an original Norton nut was used as a pattern from which these have been copied.  Because of the size of the Hex, these nuts are often badly chewed of have come loose on the bike.  Notice they have a left hand thread so are screwed on and tightened the opposite direction to most nuts.  Once fitted a star shaped lock washer should also be fitted over them - we also sell these - item no 0271 and 0272.

Sorry not cheap, but Whit hex had to be milled (to the correct original imperial Hex size) and my manufacturer also had to have special LH tap made, hence price
