Key Features & Benefits at a Glance
- Superior corrosion resistance in harsh environments thanks to premium 316 stainless steel construction
- Enhanced torque transmission and reduced cam-out with the external hex head design for reliable installation
- Stronger, more secure connections in wood achieved through thread forming technology that displaces material without cutting
- Optimized pull-out resistance and holding power from the 9 threads per inch and partially threaded shank design
- Wide compatibility with standard tools due to the 1/2" hex head width for quick and easy driving
- Long-term structural integrity ensured by compliance with rigorous ASME B18.2.1 dimensional standards
- Safe for regulated industrial applications with full RoHS 3 and REACH environmental compliance
Professional Applications & Engineering Value
These 316 stainless steel hex head wood screws deliver exceptional performance in demanding applications where corrosion resistance is critical. The thread forming design creates permanent, high-strength threads in wood by compressing the material rather than cutting it, significantly reducing the risk of stripping and providing superior pull-out strength compared to traditional cutting screws. The external hex drive allows for high-torque application with common tools, making them ideal for heavy-duty wood fastening in construction, marine environments, outdoor structures, and industrial equipment where exposure to moisture, chemicals, or salt spray would degrade ordinary fasteners. Their partially threaded configuration ensures maximum clamping force where it matters most.
Specification Summary & Compliance
This 5/16" x 1-1/4" screw features a right-hand thread direction with approximately 9 threads per inch and a minimum thread length of 0.833". Manufactured to precise ASME B18.2.1 specifications for dimensional accuracy and mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring they meet the latest environmental and safety standards for industrial use.
