S-98643A654 Length 1 3/4" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in humid or outdoor wood applications
• Enhanced driving torque and reduced cam-out thanks to the square drive design, ensuring secure installation and preventing tool slippage
• Efficient self-tapping installation with thread cutting serrations that create precise mating threads in wood without pre-drilling
• Clean, flush finishing with standard 90° flat head profile that sits neatly countersunk in wood surfaces
• Optimized thread engagement through partial threading design that provides maximum holding power while reducing driving resistance
• Reliable vibration resistance from serrated locking features that help maintain tight fastening under dynamic loads
• Compliance with international environmental standards including RoHS 3 and REACH for safe, sustainable industrial use

Professional Applications & Engineering Value

These No. 8 wood screws with 18-8 stainless steel construction address critical challenges in woodworking and construction applications. The thread cutting design with serrations eliminates the need for pre-tapping in hardwoods and composite materials, significantly reducing installation time and labor costs. The square drive system provides superior torque transmission compared to traditional Phillips heads, preventing strip-outs during high-torque applications in framing, decking, and furniture assembly. The flat head profile with 90° countersink ensures seamless flush mounting in visible applications where aesthetics matter. With partial threading and specialized tip geometry, these screws deliver exceptional pull-out resistance while minimizing wood splitting, making them ideal for demanding structural connections in outdoor structures, marine environments, and architectural woodwork where moisture resistance and long-term reliability are paramount.

Specification Summary & Compliance

These wood screws feature precision No. 8 thread diameter (0.164") with 8 TPI right-hand threads and Class 2A thread tolerances for consistent performance. The 1-3/4" length with 1.19" minimum thread length provides optimal engagement depth for various wood thicknesses. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they contain no restricted substances and meet the latest compliance standards for industrial and commercial applications worldwide.
