S-91530A400 Length 3" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-lasting performance in humid or outdoor wood applications.
• Enhanced torque transfer and reduced cam-out thanks to the square drive design, allowing for secure fastening and efficient installation.
• Self-tapping capability with thread cutting technology eliminates the need for pre-drilling in many cases, saving time and labor in wood and plastic-wood composite materials.
• Optimal thread engagement with a 10 TPI (threads per inch) design and 1 1/2" minimum thread length for strong, reliable holds in various materials.
• Clean, flush installation provided by the narrow flat head profile, ideal for applications where a smooth surface finish is required.
• Reliable partial threading ensures the unthreaded shank adds shear strength, preventing joint loosening under stress.
• Compliance with environmental and safety standards including RoHS 3 and REACH, making them suitable for regulated industrial and commercial projects.

Professional Applications & Engineering Value

These No. 7 wood screws are precision-engineered from 18-8 stainless steel to address common fastening challenges in wood and plastic-wood composite assemblies. The thread cutting tapping method and pointed tip allow for easy insertion without splitting materials, reducing installation time and tool wear. The square drive flat head design maximizes torque application, minimizing stripping and ensuring a tight, secure fit in demanding environments such as outdoor furniture, decking, and structural woodwork. Their partially threaded configuration enhances resistance to vibration and pull-out, providing reliable performance in both light and heavy-duty applications. This combination of material durability and intelligent design delivers consistent results for contractors, manufacturers, and DIY professionals seeking efficient, long-term fastening solutions.

Specification Summary & Compliance

This screw features a No. 7 size with a 0.151" thread diameter and 10 TPI right-hand threading, conforming to standard inch measurements for precise fits. The partially threaded design includes a minimum thread length of 1 1/2" and is compatible with a 1/16" drill bit for pilot holes. Manufactured to ensure dimensional accuracy, these screws comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, affirming their safety and environmental suitability for industrial use.
