ST5*25 SS316 Hex Head Wood Screws for Woodworking

The hex head enables high torque installation with wrenches and power socket drivers, achieving the clamping force needed for structural timber connections in wind-loaded or dynamically stressed structures. The coarse wood-screw thread form provides excellent pull-out resistance in softwood, hardwood, and pressure-treated timber — including timber treated with copper azole or ACQ preservatives that aggressively corrode standard carbon steel fasteners.

ST5*25 specification (5mm diameter, 25mm length) suits decking board fixing, structural timber joining, and heavy carpentry applications. Plain (natural) finish maintains full SS316 corrosion resistance without compromising screw aesthetics in visible architectural timber details.

Manufactured to DIN 571 standard. SS304 alternative available for non-marine applications. OEM/ODM customization supported.
