S-90252A250 Length 1 1/8" Wood Screws

Key Features & Benefits at a Glance

• Superior fiberboard and particleboard performance with thread forming technology that creates stronger, permanent threads without pre-tapping
• Enhanced corrosion resistance through black-oxide steel coating that protects against rust in various environmental conditions
• Clean, flush installation with 82° countersink angle and flat head design that sits perfectly flush with material surfaces
• Secure driving and reduced cam-out with Phillips No. 2 drive that provides reliable torque transfer during installation
• Optimized thread engagement featuring 11 threads per inch and 3/4" minimum thread length for maximum holding power in wood composites
• Precision installation guidance with recommended 5/64" drill bit size for proper pilot hole preparation in fiberboard applications
• Right-hand threading with pointed tip for easy starting and smooth penetration into wood composite materials

Professional Applications & Engineering Value

These No. 8 wood screws are specifically engineered to address common challenges in fiberboard and particleboard applications where traditional fasteners often fail. The thread forming design eliminates the need for pre-tapped holes while creating stronger, more durable threads that resist pull-out in low-density wood composites. The black-oxide steel construction provides essential corrosion protection for interior applications where moisture may be present. The combination of partially threaded design and 82° countersink angle ensures precise, professional finishes in cabinetry, furniture manufacturing, and construction projects. The Phillips flat head configuration delivers both aesthetic appeal and functional performance, making these screws ideal for visible applications where clean lines matter.

Specification Summary & Compliance

These wood screws feature precision inch system measurements with No. 8 screw size and 1-1/8" length. The thread forming tapping method creates permanent threads without cutting, while the right-hand thread direction with 11 threads per inch ensures standard compatibility. Manufacturing adheres to industry standards for dimensional accuracy, including head diameter tolerance of -0.04" for consistent performance. The screws are designed for use with 5/64" drill bits and feature standard 82° countersink angles for proper seating in wood composite materials.
