- Environmental compliance assurance meeting RoHS 3 and REACH standards for safe industrial use
Professional Applications & Engineering Value
These heavy-duty wood screws are engineered to solve critical fastening challenges in wood construction and structural applications. The zinc-plated steel construction provides essential corrosion protection for both indoor and outdoor projects, while the thread forming design creates permanent, high-strength connections without pre-drilling in many wood types. The external hex drive system delivers maximum torque capability, preventing cam-out during installation in dense materials. With partial threading and substantial 3/4" diameter, these screws distribute clamping forces effectively, minimizing wood splitting while providing exceptional pull-out resistance for timber framing, deck construction, and structural wood assemblies where reliability is paramount.
Specification Summary & Compliance
Manufactured to ASME B18.2.1 standards with Class 2A thread tolerances, these wood screws feature right-hand threading with approximately 4.5 threads per inch and 3" minimum thread length. The zinc-plated steel construction ensures consistent performance while meeting RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements for environmental safety and industrial use standards.
