S-90252A114 Length 1 1/4" 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 design that creates strong, permanent threads in fiberboard and particleboard
• Clean, flush installation with 82° countersink angle and flat head profile that sits perfectly flush with material surfaces
• Reduced splitting risk with pointed tip and optimized thread pitch for easier insertion in delicate wood composites
• Reliable driving performance with No. 2 Phillips drive that minimizes cam-out and ensures secure fastening
• Optimized thread engagement with 11 threads per inch and 0.838" minimum thread length for maximum pull-out resistance
• Precision installation guidance with recommended 5/64" drill bit size for proper pilot hole preparation

Professional Applications & Engineering Value

These Black-Oxide Steel wood screws are specifically engineered to address common challenges in fiberboard and particleboard applications, where traditional fasteners often cause material splitting or poor holding strength. The thread forming technology eliminates the need for pre-tapped holes while creating compression-fit threads that significantly increase pull-out resistance in low-density wood composites. The 82° countersink angle and flat head design ensure seamless surface finishing in cabinetry, furniture manufacturing, and architectural woodworking. With partial threading and optimized 11 threads per inch configuration, these screws provide superior clamping force without compromising material integrity, making them ideal for professional woodworking projects requiring reliable, long-term fastening solutions in engineered wood products.

Specification Summary & Compliance

Manufactured to inch system standards with 0.164" thread diameter and Class 2A thread tolerance for consistent performance. These wood screws feature right-hand threading and standard flat head profile compliant with industry specifications. The manufacturing process adheres to quality standards suitable for professional woodworking applications, ensuring dimensional accuracy and reliable performance in fiberboard and particleboard installations.
