S-90000A155 Length 1 1/4" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in demanding environments
• Enhanced driving torque and reduced cam-out thanks to the square drive design, ensuring secure installation and preventing tool slippage
• Efficient self-tapping installation in wood and plastic-wood composites with Type 17 thread cutting tip, eliminating the need for pre-drilling in many applications
• Optimal material holding power achieved through partial threading, which increases grip strength and reduces the risk of material splitting
• Flush, low-profile finish with the standard flat head, providing a clean appearance and preventing surface protrusion
• Reliable dimensional consistency with a No. 6 screw diameter and 1-1/4" length, ensuring predictable performance and easy replacement
• Compliance with major environmental regulations including RoHS 3 and REACH, making them suitable for regulated industrial and construction projects

Professional Applications & Engineering Value

These 18-8 stainless steel wood screws are engineered to solve common fastening challenges in wood and plastic-wood composite materials. The Type 17 thread cutting tip acts like a drill bit, creating its own mating thread as it's driven. This eliminates the need for separate pilot holes in many softwoods and composites, significantly speeding up assembly lines and reducing labor costs. The square drive provides superior torque transfer compared to Phillips heads, preventing cam-out and driver damage during high-torque applications. The partially threaded shank design concentrates the holding power along the engaged portion, pulling materials tightly together while minimizing the risk of splitting brittle composites. This combination of thread cutting technology and corrosion-resistant stainless steel makes these screws ideal for outdoor furniture, decking, and construction applications where durability and installation efficiency are critical.

Specification Summary & Compliance

This No. 6 x 1-1/4" wood screw features a 0.138" thread diameter with 9 threads per inch and a minimum thread length of 0.825". Manufactured with a standard flat head profile and square drive (No. 2 size), it's designed for right-hand threading applications. The screws are RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent international standards for hazardous substance restrictions and chemical safety in industrial components.
