High Tensile Stainless Steel Cylinder Stud Set for 600cc engines (set of 4).
The pattern for these was taken from a postwar (1949) Manx 600 engine, but they should also fit the pre-war 596 engines.
Footnote: you might not recognize the 'A15' designate, but '15' was the model number allocated to 600 OHC machines . . . it is not listed in any catalogs though!
We normally sell these high quality engine studs as a set of 4, but we do occasionally sell them individually if required (slightly more, if bought as a single stud) - email us for availability of single studs
