Product details

Driver bit to suit 3.4mm square screw head hole. Specifically required to drive the AR-SCR-BR-50PK 12g x 25mm panhead rail screws used to fix the undercapping rail to the post screw flutes (catalogue page 16: 'Suits AR-SCR-BR-50PK screws'). Square drive heads grip better than Phillips and are less prone to cam-out under load - important for the rail-to-post connection where torque control matters.
