Primary Chain Tension Adjusting Screwdriver Tool Triumph BSA

Slotted Fasteners Can Be A Pain

Seems like every type of slotted fastener is made to NOT fit quality screw drivers. You know what I mean, you turn the fastener, it starts to sugg up and zap the blade spins out rearranging the metal at the screw head and not in a good way. It’s a good practice to customize ones screwdrivers by grinding or filing until the blade fits the slot with no slop. It’s no different for the primary chain tension adjusting tool make sure it matches the slot in the screw with no wiggle. Now you have the perfect tool that won’t spin out in the screw head.
