BSA B25 B44 Triumph TR25W Engine Cover Allen Screw Set Stainless Steel UNC 1969-1970 PN# TBS-08-9201

This complete outer case cover socket-head screw set is suitable for fitment to the BSA 250 and 441 single-cylinder models, as well as the Triumph 250 singles from 1969-1970. Offered in corrosion-resistant stainless steel, this complete set of screws is threaded to 1/4″-20 TPI UNC. Included are the 2BA points cover screws. Not suitable for fitment to 1968 and earlier models with BSF screws. 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 chaincase. Thread-locking compound is not recommended for use on cover sccrews. The product images shown are for illustrative purposes only and may not be an exact representation of the product received.
