S-90031A135 Length 1 1/4" Wood Screws

Key Features & Benefits at a Glance

• Superior holding power with thread forming technology that creates strong, permanent threads in wood without pre-tapping
• Enhanced corrosion resistance through zinc-plated steel construction for long-lasting performance in various environments
• Optimized wood engagement with partial threading design that provides maximum pull-out resistance while reducing splitting
• Effortless installation with Phillips No. 2 drive that ensures secure tool engagement and reduces cam-out incidents
• Versatile material compatibility with specific drill bit recommendations for both hardwood (5/64") and softwood (1/16") applications
• Clean finished appearance with standard flat head profile that sits flush with wood surfaces for professional results
• Reliable dimensional consistency with precise 0.125" thread diameter and 20 threads per inch for predictable performance

Professional Applications & Engineering Value

These No. 5 zinc-plated steel wood screws are engineered to address common challenges in wood joining applications, particularly where vibration resistance and long-term structural integrity are critical. The thread forming technology creates compressed wood fibers around the threads, resulting in significantly higher pull-out strength compared to conventional wood screws. The partially threaded shank design allows the unthreaded portion to act as a dowel, preventing joint separation while the threaded section provides exceptional holding power. The zinc-plated steel construction offers reliable protection against corrosion in interior applications, making these Phillips flat head screws ideal for furniture assembly, cabinetry, wood framing, and general construction where flush mounting is required for both hardwood and softwood materials.

Specification Summary & Compliance

These wood screws feature a 0.125" thread diameter with 20 threads per inch and partial threading extending approximately 0.833" from the pointed tip. The standard flat head profile with 82° countersink angle ensures proper seating in wood surfaces. Manufactured to precise dimensional standards with right-hand threading and thread forming tapping method. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for safe use in commercial and residential applications.
