• Versatile right-hand threading compatible with standard installation equipment and procedures

Professional Applications & Engineering Value

This black oxide steel hex head wood screw delivers critical engineering advantages for wood construction and industrial assembly. The thread forming design creates permanent, vibration-resistant connections by compressing wood fibers rather than cutting them, eliminating the need for pilot holes in many applications. The external hex drive provides maximum torque capability for high-tension fastening in structural timber, pallet manufacturing, and heavy-duty furniture. With partial threading concentrating grip strength along the engagement zone, this fastener prevents material splitting while maintaining superior pull-out resistance. The corrosion-resistant black oxide finish ensures reliable performance in both indoor and protected outdoor environments, making it ideal for construction, manufacturing, and maintenance operations where wood fasteners must withstand mechanical stress and environmental exposure.

Specification Summary & Compliance

This 5/16" x 2-1/2" wood screw features precision right-hand threads with approximately 9 threads per inch and a minimum thread length of 1-3/4". Manufactured to ASME B18.2.1 dimensional standards for consistent quality and performance. The product is fully compliant with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety, ensuring environmental responsibility and workplace safety compliance.
