S-90252A261 Length 1 3/4" Wood Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with black-oxide steel construction, extending service life in demanding woodworking environments.
• Superior torque transfer and reduced cam-out thanks to the No. 2 Phillips drive, ensuring efficient installation and driver bit longevity.
• Eliminates the need for pre-drilling in most applications via the thread-forming tapping method, saving time and labor costs.
• Flush, professional finish achieved with the standard flat head profile and precise 82° countersink angle, ideal for visible applications.
• Exceptional holding power in fiberboard and particleboard due to the 0.177" thread diameter and 10 threads per inch, providing a secure, vibration-resistant connection.
• Optimized for quick, straight starts with a pointed tip and partially threaded shank, minimizing material splitting and ensuring accurate placement.
• Reliable performance in right-hand thread applications with a minimum thread length of 1.17", ensuring deep engagement and consistent clamping force.

Professional Applications & Engineering Value

These black-oxide steel particleboard screws are precision-engineered to address common challenges in woodworking and construction, such as material splitting and inefficient installation. The thread-forming design creates strong, permanent threads in fiberboard and particleboard without pre-drilling, reducing labor and tool wear. The 82° countersink angle and flat head profile ensure a seamless, flush finish, critical for furniture assembly, cabinetry, and architectural millwork where aesthetics matter. Combined with the Phillips drive for high-torque application, these screws deliver reliable, long-lasting fastening solutions that withstand vibrational stresses and environmental exposure, making them ideal for professional-grade woodworking projects.

Specification Summary & Compliance
