This complete 22-piece outer case cover screw set is suitable for fitment to the late unit-construction BSA A50 and A65 twins from 1969-1972. This set includes the screws for the primary chaincase and outer timing cover, as well as the tachometer cable adaptor.

Sourced from the UK and threaded to 1/4″-20 TPI UNC, this set contains replacements for (2) 21-5370 2BA x 9/16″, (6) 21-1917 1/4″-20 x 2-1/2″, (7) 21-1854 1/4″-20 x 1-7/16″, (6) 14-6611 1/4″-20 x 1-3/4″, and (1) 21-1951 1/4″-20 x 1-7/8″ screws. These screws are stainless steel with Allen heads.

The socket heads are a convenient upgrade for routine clutch service and timing cover removal, providing a positive engagement with the Allen wrench used for loosening and tightening the screws. The bright stainless finish provides a durable and attractive upgrade from the original fillister head screws.

It is advisable to clean the threads in the crankcase with a tap to allow for best thread retention and an oil-tight seal between the primary chaincase cover and the crankcase. Thread locking compound is not recommended for use on cover screws.
