S-90123A421 Length 1 1/2" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 316 stainless steel construction, ideal for humid or chemically aggressive woodworking environments
• Superior holding power through thread forming technology that displaces material without removing it, creating tighter engagement
• High-torque installation capability with external hex drive design, allowing for secure fastening in demanding wood applications
• Optimized thread engagement with partial threading design that concentrates threads where needed most for maximum grip strength
• Reliable dimensional consistency meeting ASME B18.2.1 specifications, ensuring proper fit and predictable performance
• Environmental compliance assurance with RoHS 3 and REACH compliance, suitable for regulated industrial applications
• Versatile wood fastening solution combining 1-1/2" length with 1/2"-13 thread pitch for heavy-duty wood construction and assembly

Professional Applications & Engineering Value

This 316 stainless steel hex head wood screw delivers exceptional performance in demanding wood applications where corrosion resistance and structural integrity are paramount. The thread forming technology eliminates chip removal issues common in wood fastening, creating stronger thread engagement by compressing wood fibers rather than cutting them. The external hex drive provides superior torque transmission compared to standard drives, preventing cam-out during high-torque installation in hardwoods or composite wood materials. With its partial threading design, the screw concentrates holding power where needed most, reducing the risk of wood splitting while maintaining excellent pull-out resistance. These engineering features make it ideal for outdoor structures, marine applications, industrial wood framing, and any environment where moisture, chemicals, or temperature variations would compromise ordinary fasteners.

Specification Summary & Compliance

This 1/2"-13 x 1-1/2" wood screw features inch system measurements with precise dimensional control meeting ASME B18.2.1 standards. The right-hand threaded fastener has a 0.5" thread diameter with approximately 6 threads per inch and minimum 1" thread length. Manufacturing compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance compliance for industrial distribution and use.
