S-95452A139 Length 1 1/2" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black oxide steel coating that protects against rust in demanding woodworking environments
• Maximum torque application through the external hex head design that prevents cam-out and allows high tightening force
• Enhanced holding power from thread forming technology that compresses wood fibers rather than cutting them
• Easier installation with pointed tip and partial threading that reduces splitting while maintaining strong engagement
• Reliable performance with 1/2" diameter and 6 threads per inch providing optimal strength for heavy-duty applications
• Industry compliance meeting ASME B18.2.1 standards for dimensional accuracy and mechanical properties
• Environmental responsibility through RoHS 3 and REACH compliance for safe, sustainable manufacturing

Professional Applications & Engineering Value

These black oxide steel wood screws are engineered to solve critical challenges in wood construction and fabrication. The thread forming design creates permanent, vibration-resistant connections by compressing wood fibers rather than removing material, eliminating weak points common with traditional cutting threads. The external hex drive system ensures maximum torque transfer without stripping, crucial for structural applications where fastener integrity is paramount. With partial threading and optimal 6 TPI count, these screws provide concentrated holding power where needed most while minimizing wood splitting. The black oxide coating offers essential corrosion protection in environments where moisture or outdoor exposure could compromise fastener performance, making them ideal for furniture manufacturing, deck building, and structural wood assemblies requiring long-term reliability.

Specification Summary & Compliance

This 1/2" x 1-1/2" wood screw features inch system measurements with Class 2A thread tolerances per ASME B18.2.1 specifications. The right-hand threaded design with 6 threads per inch and 1-1/4" minimum thread length ensures proper engagement in wood substrates. Manufacturing complies with ASME B18.2.1 dimensional and mechanical standards, while environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations for restricted substance management.
