S-91550A308 Length 3/4" Wood Screws

Key Features & Benefits at a Glance

• Enhanced Corrosion Resistance: Zinc-plated steel construction provides reliable protection against rust, ensuring long-term durability in various environments.
• Superior Holding Power: Thread-forming technology with 15 TPI creates strong, permanent threads in wood, maximizing pull-out resistance and joint integrity.
• Flush, Professional Finish: Standard flat head with 90° countersink angle allows the screw to sit perfectly flush with the material surface for a clean, snag-free installation.
• Versatile Drive Compatibility: Combined Phillips/Square (No. 2) drive offers flexibility, reducing cam-out and tool slippage for efficient driving with common bits.
• Full-Length Thread Engagement: Fully threaded design ensures consistent grip along the entire shank, providing exceptional holding strength in plywood and OSB.
• Optimized for Wood Materials: Pointed tip and specified 5/64" drill bit size enable easy, precise starting and reduced splitting in plywood and oriented strand board.
• Environmentally Compliant: Meets RoHS 3 standards, ensuring safe use by restricting hazardous substances in line with EU directives.

Professional Applications & Engineering Value

These No. 8 wood screws are precision-engineered to address common challenges in woodworking and construction, such as material splitting and weak fastening in engineered wood products. The zinc-plated steel material offers a balance of strength and corrosion resistance, ideal for indoor and protected outdoor applications. The thread-forming design eliminates the need for pre-tapped holes, creating tight, durable threads that resist loosening under vibration and load. This is particularly valuable in plywood and OSB applications, where the fully threaded shank and 15 TPI provide maximum surface contact and holding power. The flat head with a 90° countersink ensures a seamless finish, reducing snagging risks and improving aesthetics in cabinetry, framing, and assembly projects.

Specification Summary & Compliance

This screw features a No. 8 size with a 0.164" thread diameter and 3/4" length, adhering to inch system standards. The fully threaded, right-hand design with a pointed tip ensures easy installation. It is manufactured to precise dimensions, including a 0.3" head diameter and standard flat head profile, and is compliant with RoHS 3 (2015/863/EU) environmental regulations, confirming the absence of restricted hazardous substances.
