Key Features & Benefits at a Glance
- Superior corrosion resistance in harsh environments thanks to 316 stainless steel construction, ideal for outdoor or high-moisture wood applications.
- Maximum torque application and secure installation enabled by the external hex head design, preventing cam-out and ensuring a tight, reliable fit.
- Excellent holding power and reduced wood splitting from the thread forming tapping method, which displaces material to create strong, permanent threads.
- Optimized grip and material savings with a partially threaded shank, providing a firm hold while minimizing unnecessary threading.
- Heavy-duty performance for demanding projects with a substantial 4" length and 1/2" diameter, suitable for thick wood sections and structural applications.
- Reliable, standardized performance ensured by compliance with the rigorous ASME B18.2.1 specification for dimensional accuracy and mechanical properties.
- Safe for regulated industries with RoHS 3 and REACH compliance, meeting strict environmental and health standards.
Professional Applications & Engineering Value
Engineered for heavy-duty wood construction and industrial applications, this 316 stainless steel hex head wood screw solves critical challenges like fastener failure in corrosive or high-stress environments. The thread forming technology eliminates the need for pre-tapped holes, creating stronger threads in wood that resist pull-out and vibration loosening. The external hex drive allows for high-torque installation with standard tools, ensuring a secure connection in timber framing, decking, and outdoor structures. Its partial threading concentrates holding power where it's needed most, making it an essential industrial wood fastener for projects requiring long-term durability and reliability against the elements.
Specification Summary & Compliance
This screw features a 1/2"-13 thread with a right-hand direction and is manufactured to the dimensional and mechanical requirements of ASME B18.2.1. It is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for use in regulated markets and environmentally sensitive applications.
