Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding wood applications
- Maximum torque transmission through the 1/2" external hex head design, preventing tool slippage during installation
- Enhanced holding power with thread forming technology that creates stronger, more secure connections in wood materials
- Full-length threading (1-1/8" minimum thread length) ensures consistent grip strength along the entire fastener length
- Precision engineering with 9 threads per inch and pointed tip for easier starting and reduced splitting in wood
- Industry-standard compliance meeting ASME B18.2.1 specifications for reliable dimensional accuracy and performance
- Environmental responsibility through RoHS 3 and REACH compliance, ensuring safe use in regulated applications
Professional Applications & Engineering Value
These 5/16" hex head wood screws are engineered to solve critical fastening challenges in wood construction and assembly 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 by displacing material rather than removing it. This eliminates the need for pre-tapping and reduces the risk of wood splitting. The external hex drive configuration delivers superior torque capability for high-tension applications, making these fully threaded screws ideal for heavy-duty framing, structural wood connections, and industrial wood manufacturing where vibration resistance and long-term reliability are paramount.
Specification Summary & Compliance
Manufactured to exacting ASME B18.2.1 standards with Class 2A thread tolerances, these wood screws feature a 5/16" thread diameter, 1-1/4" overall length, and 9 threads per inch configuration. The zinc-plated steel construction meets rigorous industry specifications for dimensional accuracy and mechanical properties. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and workplace safety, making these screws suitable for regulated industries and international projects requiring certified components.
