S-90000A295 Length 3 1/2" Wood Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 316 stainless steel construction, ideal for humid or outdoor environments in wood and plastic-wood composite applications.
• Superior holding power due to the thread cutting design (Type 17), which reduces splitting and ensures secure fastening without pre-drilling in many cases.
• Enhanced torque transmission from the square drive and flat head, providing a non-slip grip and allowing for flush installation in various materials.
• Optimized thread engagement with 13 threads per inch and partial threading, offering balanced pull-out strength and reduced material stress.
• Durable and long-lasting performance in demanding conditions, backed by compliance with RoHS 3 and REACH environmental regulations.
• Versatile application range from furniture assembly to composite decking, thanks to the pointed tip and 3-1/2" length for deep penetration.

Professional Applications & Engineering Value

These 316 stainless steel wood screws are engineered to address common challenges in wood and plastic-wood composite fastening, such as material splitting and corrosion-induced failure. The thread cutting technology (Type 17) and pointed tip enable easy insertion with minimal effort, reducing installation time and tool wear. By utilizing a square drive flat head, these screws offer reliable torque resistance, preventing cam-out and ensuring a clean, flush finish. The partial threading design concentrates holding force where it's needed most, enhancing joint integrity in structural applications like outdoor decking, marine fixtures, and furniture. With their high corrosion resistance and compliance with strict standards, these screws deliver long-term reliability in moisture-prone environments, making them a cost-effective choice for professionals seeking durability and regulatory adherence.

Specification Summary & Compliance

This product adheres to standard inch measurements with a No. 10 screw size, 0.19" thread diameter, and 13 threads per inch for consistent performance. The flat head profile and square drive (No. 2 size) ensure precise installation, while the partially threaded shank with a minimum thread length of 2.31" provides optimal grip. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), confirming the absence of hazardous substances and supporting environmental safety in industrial and consumer applications.
