Fischer 573051 Spax screw 55 mm TX 500 pc(s)

These wood screws are designed to join timber and chipboard components by converting rotational torque into axial clamping force as the helical thread advances into the substrate. Installation is straightforward with a TX20 driver, where the drive engagement controls torque delivery and minimises slippage during driving. The countersunk head seats into the material, distributing compressive loads across the surface and enabling a flush finish suitable for visible work. Partial threading concentrates the holding action along the shank beneath the head while the plated surface helps reduce surface corrosion in typical construction and decking tasks. Typical uses include structural timber joints, fixings into chipboard and general carpentry where reliable mechanical fastening is required.
