S-90252A253 Length 2 1/2" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with Black-Oxide steel coating, extending service life in demanding woodworking environments
• Enhanced holding power through thread-forming design that creates permanent, vibration-resistant connections in fiberboard and particleboard
• Clean, flush installation with 82° countersink angle and standard flat head profile for professional finished appearances
• Optimized thread engagement with 11 threads per inch and 1.675" minimum thread length for maximum pull-out resistance
• Efficient installation using standard No. 2 Phillips drive and pre-drilling with 5/64" bit for quick, secure fastening
• Reduced material splitting through pointed tip and partial threading design that minimizes stress on wood composites
• Precision dimensional control with head diameter tolerance of -0.04" ensuring consistent performance across applications

Professional Applications & Engineering Value

These Black-Oxide steel wood screws are engineered specifically for fiberboard and particleboard applications where traditional fasteners often fail. The thread-forming tapping method creates strong, permanent threads in composite wood materials without pre-tapping, eliminating strip-out issues common in low-density substrates. The 82° countersink angle and flat head profile ensure seamless flush mounting in cabinetry, furniture, and construction assemblies. With right-hand threading and partial threading design, these screws provide concentrated holding power where needed most while reducing installation torque and material stress. The combination of 0.164" thread diameter and 11 threads per inch delivers optimal bite in engineered wood products, making them ideal for professional woodworking and manufacturing applications requiring reliable, long-lasting fastening solutions.
