DIN 571 Plain Hex Head Wood Screws

The external hexagonal head enables installation with standard wrenches and power sockets — delivering significantly higher torque than slotted or cross-head wood screws, and allowing reliable tightening in heavy timber, engineered wood, and glulam structural connections.
The coarse thread profile and tapered point penetrate dense hardwoods and engineered wood products without splitting, providing excellent pull-out resistance and shear strength in structural joints. 
SS304 stainless steel ensures the screws remain free of rust staining — essential for visible timber structures, outdoor furniture, marine decking, and food-production facility framing.
Size ST5*25 (5mm diameter, 25mm length) suits light structural timber connections, decking boards, and general carpentry assemblies. 
Manufactured to DIN 571 standard, ensuring dimensional compatibility with standard hex-head tooling and consistent quality across production batches.
SS316 available for coastal marine and chemical environments. Carbon steel with Zinc or HDG finish for indoor or temporary applications. OEM/ODM customization supported.
