S-90252A258 Length 1" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with Black-Oxide Steel coating, extending screw life in various environmental conditions
• Enhanced holding power through thread forming technology that creates strong, permanent threads in fiberboard and particleboard
• Clean, flush installation with 82° countersink angle and flat head design that sits perfectly flush with material surfaces
• Reliable driving performance with Phillips No. 2 drive that provides secure bit engagement and reduces cam-out
• Full-length threading ensures maximum grip along the entire screw length for superior pull-out resistance
• Precision sizing with No. 9 diameter and 1" length optimized for fiberboard applications requiring specific fastening requirements
• Easy installation with pointed tip that starts quickly and reduces material splitting in wood composites

Professional Applications & Engineering Value

These Black-Oxide Steel wood screws are specifically engineered for demanding fiberboard and particleboard applications where traditional fasteners often fail. The thread forming technology eliminates the need for pre-tapped holes while creating superior holding strength that resists pull-out in low-density wood composites. The 82° countersink angle combined with the flat head design ensures a perfectly flush finish that prevents surface protrusions in cabinetry, furniture manufacturing, and construction applications. The Phillips drive system with No. 2 size provides reliable torque transfer during installation, reducing driver slippage and improving assembly efficiency in production environments. These fully threaded screws with 10 threads per inch deliver maximum engagement in composite wood materials, making them ideal for professional woodworking and industrial manufacturing applications requiring consistent, high-performance fastening solutions.

Specification Summary & Compliance

These No. 9 x 1" wood screws feature precision inch system measurements with 0.177" thread diameter and 10 threads per inch for consistent performance. The flat head design maintains standard profile specifications with 0.358" head diameter and 0.108" head height, ensuring proper countersinking. Manufactured to industry standards for thread forming screws with right-hand threading and pointed tip configuration. Recommended for use with No. 45 drill bit (0.082" diameter) for optimal installation in fiberboard and particleboard substrates. Complies with standard industrial specifications for wood screw applications in construction and manufacturing environments.
