S-90000A281 Length 1 1/4" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for humid or chemically aggressive environments in wood and composite applications
• Enhanced drive stability from the square drive design, reducing cam-out and ensuring secure, efficient installation with standard tools
• Self-tapping efficiency through thread cutting technology, eliminating the need for pre-drilling in many wood and plastic-wood composite materials
• Optimal material engagement with 15 threads per inch and 0.164" thread diameter, providing strong pull-out resistance and vibration resistance
• Flush, low-profile installation thanks to the standard flat head design, minimizing surface protrusion for cleaner finished appearances
• Regulatory compliance assurance meeting RoHS 3 and REACH standards, ensuring safe, environmentally responsible manufacturing
• Versatile partial threading allowing unthreaded shank sections to act as precision pilots for accurate alignment in wood assemblies

Professional Applications & Engineering Value

These 316 stainless steel wood screws address critical fastening challenges in wood and plastic-wood composite applications where moisture exposure and material integrity are primary concerns. The thread cutting design creates precise mating threads in base materials, eliminating stripping and reducing installation torque requirements. The square drive system provides superior torque transmission compared to Phillips drives, preventing tool slippage during high-torque applications. With their partial threading configuration, these screws allow the unthreaded shank to guide the screw precisely while the threaded portion delivers maximum holding power. This combination makes them ideal for outdoor furniture, decking, marine applications, and architectural woodwork where corrosion resistance and long-term structural integrity are paramount.

Specification Summary & Compliance

These No. 8 x 1-1/4" wood screws feature standard inch system measurements with a thread diameter of 0.164" and approximately 15 threads per inch. The flat head profile follows industry standards for countersunk applications. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety. The thread cutting tapping method (Type 17) and right-hand threading provide reliable fastening performance in wood and plastic-wood composite materials with recommended 5/64" pilot holes for optimal installation.
