S-91550A313 Length 1 1/4" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-term durability in various environmental conditions.
• Enhanced driving efficiency through the Phillips/Square combo drive, reducing cam-out and allowing for quick, secure installation.
• Excellent holding power in plywood and OSB due to the thread-forming design, which creates strong, reliable threads without pre-tapping.
• Full threading along the entire length for maximum grip and pull-out resistance in wood applications.
• Optimized for woodworking with a pointed tip and standard flat head profile, enabling easy starting and flush finishing.
• Precise fit and reduced splitting with recommended 3/32" drill bit size, ensuring clean installations in dense materials.
• Compliance with environmental standards via RoHS 3, making them safe for use in regulated projects and sustainable practices.

Professional Applications & Engineering Value

These No. 10 wood screws are engineered to address common challenges in woodworking and construction, such as material splitting and weak fastening in engineered woods like plywood and OSB. Made from zinc-plated steel, they resist rust and corrosion, extending service life in humid or outdoor settings. The thread-forming design eliminates the need for separate tapping, reducing installation time and enhancing thread integrity by compressing wood fibers for a tighter hold. With a Phillips/Square combo drive, users benefit from versatile tool compatibility and reduced slippage, improving efficiency on job sites. The flat head sits flush for a clean finish, while the fully threaded shank ensures consistent load distribution, making these screws ideal for furniture assembly, framing, and other woodworking applications requiring reliable, long-lasting connections.

Specification Summary & Compliance

This product adheres to standard inch measurements with a thread diameter of 0.19" and approximately 13 threads per inch for precise engagement. The flat head features a 90° countersink angle, and the screws are fully threaded with a right-hand direction for ease of use. Compliance includes RoHS 3 (2015/863/EU), ensuring they are free from hazardous substances and suitable for environmentally conscious projects. Manufactured to common industry tolerances, these screws are designed for reliability in wood screw applications, supporting quality and safety in professional settings.
