S-91540A100 Length 1" 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 environments.
• Enhanced weather sealing provided by the integrated stainless steel/rubber washer to prevent moisture ingress and material damage.
• High-torque installation capability thanks to the square drive design, reducing cam-out and ensuring secure fastening.
• Efficient self-tapping installation with Type 17 thread-cutting tip that eliminates pre-drilling in many wood and plastic applications.
• Optimal thread engagement with 7/8" minimum thread length for strong holding power in various material thicknesses.
• Flush mounting compatibility with standard flat head profile for clean, recessed installations in wood and composite surfaces.
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe use in industrial and commercial applications.

Professional Applications & Engineering Value

These heavy-duty wood screws solve critical fastening challenges in wood, plastic, and composite materials through their specialized engineering. The 18-8 stainless steel composition provides exceptional resistance to rust and corrosion, making them ideal for outdoor structures, marine applications, and high-moisture environments. The thread-cutting design with Type 17 tapping screw configuration enables easy penetration without splitting materials, while the integrated sealing washer creates a waterproof barrier that protects against weather elements. The square drive system delivers maximum torque transfer during installation, preventing stripping and ensuring consistent clamping force. These features combine to create reliable, long-lasting connections in decking, furniture, fencing, and plastic-wood composite installations where durability and weather resistance are paramount.

Specification Summary & Compliance

This No. 7 wood screw features precise inch system dimensions including 1" length, 0.151" thread diameter, and 16 threads per inch. The partially threaded design with 7/8" minimum thread length ensures optimal holding strength. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and restricted substance compliance. The screw utilizes standard right-hand threading and is engineered for use with 1/16" drill bits when pre-drilling is required.
