Here you have one pair (2) BSA Rear-wheel adjuster bolts and nuts, made from solid stainless steel and as a direct replacement for the originals.

These bolts (42-6040) screw directly into the end of the swingarm and are used to adjust the wheel and chain, the locknut (24-0563) is then used to lock and hold everything into place.

Unlike many others, on the market, ours has been produced with all the features needed for correct fitment, such as the special reduced head size on the lock nut.


This kit contains the following parts:

2 X 42-6040 - Adjuster bolts

2 X 24-0563 - Adjuster screw locknut


Finish: Polished - Tumbler

Material: Stainless steel


Each of the parts has had at least 3 hours in our tumbler, this gives them a good finish, please see photos! The finish is not "chrome" or "show finish".


These bolts were fitted to a large number of BSA swing arm models including.

A7, A10, B31, B32, B33, B34, and Goldstar (DBD34)

These bolts may fit other models but please check your part numbers before ordering.


This item is made using CNC manufacturing in England by CPC Engineering with high-quality stainless steel.
