S-95452A145 Length 4 1/2" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black oxide steel construction for extended service life in demanding wood applications
• Enhanced holding power through thread forming technology that creates stronger, more permanent connections in wood materials
• Optimized load distribution with partial threading design that concentrates grip strength where needed most
• High-torque installation capability featuring external hex drive and 3/4" head width for secure tool engagement
• Reduced material splitting with pointed tip design that guides the screw smoothly into wood substrates
• Reliable performance standardization meeting ASME B18.2.1 specifications for consistent quality and interchangeability
• Environmental compliance assurance with RoHS 3 and REACH compliance for responsible manufacturing standards

Professional Applications & Engineering Value

These black oxide steel hex head wood screws deliver exceptional engineering value through their specialized thread forming technology and partial threading design. The thread forming method displaces wood fibers rather than removing them, creating denser material around the threads for significantly improved pull-out resistance. This is particularly valuable in structural wood applications where vibration resistance and long-term connection integrity are critical. The external hex drive configuration provides superior torque transmission compared to traditional screw drives, reducing cam-out incidents during high-torque installation in hardwoods and engineered wood products. The 2 3/4" minimum thread length ensures adequate engagement in thick wood members, while the black oxide surface treatment offers reliable corrosion protection in interior applications and moderate environments. These features combine to address common wood fastening challenges including joint loosening, material splitting, and installation efficiency.

Specification Summary & Compliance

This 1/2" x 4-1/2" wood screw features a 0.5" thread diameter with 6 threads per inch in right-hand direction and Class 2A thread fit per ASME standards. The screw maintains 2 3/4" minimum thread length with partial threading and pointed tip configuration. Manufacturing and quality control adhere to ASME B18.2.1 specifications for dimensional consistency and mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety, confirming environmental responsibility in its production and composition.
