S-91550A325 Length 3 1/2" 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 torque transfer and reduced cam-out thanks to the dual Phillips/Square drive system for efficient installation
• Optimal thread engagement with a 2-3/8" minimum thread length, providing maximum holding power in wood materials
• Clean, flush installation enabled by the standard flat head profile and 90° countersink angle for professional finishes
• Reduced splitting and secure fastening in plywood and OSB due to the thread-forming tapping method and pointed tip design
• Versatile compatibility with a No. 10 screw size and 0.19" thread diameter, suitable for a wide range of wood construction projects
• Compliance with environmental standards as RoHS 3 compliant, meeting regulatory requirements for industrial use

Professional Applications & Engineering Value

These No. 10 zinc-plated steel wood screws are engineered to address common challenges in woodworking and construction, such as material splitting and weak joint integrity. The thread-forming design creates strong, permanent threads in plywood and OSB, minimizing the risk of cracking while ensuring high pull-out resistance. With a partially threaded shank and pointed tip, they facilitate easy alignment and reduce installation effort, enhancing productivity on-site. The Phillips/Square dual drive offers flexibility for various tools, preventing slippage and improving torque application in demanding applications like furniture assembly, framing, and structural wood projects. This combination of material strength and precision engineering delivers reliable performance in heavy-duty environments.

Specification Summary & Compliance

These screws feature a thread diameter of 0.19" with approximately 13 threads per inch, adhering to standard inch measurements for consistent fit. The flat head with a 90° countersink angle ensures proper seating in wood surfaces, while the No. 2 drive size supports common tool bits. Manufactured from zinc-plated steel, they comply with RoHS 3 (2015/863/EU) regulations, confirming they are free from hazardous substances and suitable for industrial and commercial use without environmental concerns.
