S-95452A165 Length 3 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 torque transmission through external hex drive design prevents stripping and ensures secure fastening
• Optimized thread engagement with 4.5 TPI thread forming design creates stronger, more permanent connections in wood
• Reduced splitting risk with partially threaded shank that minimizes stress concentration in wood materials
• Maximum driving efficiency with 1 1/8" hex head providing ample tool contact surface for high-torque applications
• Reliable performance standardization through ASME B18.2.1 compliance ensuring consistent quality and interchangeability
• Environmental regulation compliance meeting RoHS 3 and REACH standards for safe industrial use

Professional Applications & Engineering Value

These 3/4" wood screws with black oxide steel construction and thread forming design address critical challenges in woodworking and construction applications. The 4.5 TPI coarse thread profile combined with thread forming tapping method creates superior holding power without requiring pre-tapped holes, eliminating the need for additional preparation steps. The external hex drive and substantial 1 1/8" hex head provide exceptional torque transmission capability, preventing cam-out during high-stress installation in hardwoods and engineered wood products. The partially threaded design with 2 1/4" minimum thread length ensures optimal clamping force distribution while minimizing wood splitting in structural applications, making these screws ideal for heavy-duty wood construction, timber framing, and industrial wood assembly where reliability and durability are paramount.

Specification Summary & Compliance

These wood screws feature precision right-hand threads with standard inch measurements including 0.75" thread diameter, 4.5 TPI thread pitch, and 3 1/2" overall length. Manufactured to ASME B18.2.1 specifications ensuring dimensional accuracy and performance reliability. The products are fully compliant with RoHS 3 (2015/863/EU) restrictions on hazardous substances and meet REACH (EC 1907/2006) requirements for chemical safety, making them suitable for industrial and commercial applications with strict regulatory requirements.
