Fischer 573089 Spax screw 20 mm TX 1000 pc(s)

This wood screw is designed to pull components together by converting rotational torque into linear clamping force via its threaded portion. During installation the indexed TX10 recess accepts a corresponding driver to transmit torque while the thread advances the screw into timber or board, drawing materials into contact as the countersunk head seats beneath the surface. The partial thread concentrates holding force where shear loads occur, helping control panel deformation during fixation. Supplied with a plated finish, the fastener is intended for typical interior joinery and panel assembly operations where secure, flush fittings are required and straightforward powered installation is preferred.
