S-90031A128 Length 1/2" 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
• Flush, professional finish with standard flat head design that sits perfectly in 82° countersink applications
• Easy installation and removal with No. 2 Phillips drive that provides secure tool engagement and reduces cam-out
• Optimized wood penetration through pointed tip and partial threading that maximizes grip while minimizing splitting
• Versatile material compatibility with specific drill sizes for both hardwood (5/64") and softwood (1/16") applications
• Reliable industrial compliance meeting RoHS 3 and REACH standards for safe, regulated use

Professional Applications & Engineering Value

These No. 5 zinc-plated steel wood screws are engineered to solve common fastening challenges in woodworking and construction applications. The thread forming technology eliminates the need for pre-tapped holes while creating superior pull-out resistance, making them ideal for furniture assembly, cabinetry, and structural wood connections. The Phillips flat head design ensures clean, flush installations that won't protrude or snag, while the precise 82° countersink angle matches standard drill bits for professional results. The partially threaded shank provides maximum holding power by allowing the unthreaded portion to act as a dowel, preventing wood splitting while the threaded section delivers exceptional grip. These features combine to create reliable, long-lasting connections in both hardwood and softwood applications, reducing installation time and improving overall project quality.

Specification Summary & Compliance

These wood screws feature a No. 5 size with 1/2" length and 0.125" thread diameter with approximately 20 threads per inch in right-hand direction. The partially threaded design provides minimum thread length of 0.333" with standard flat head profile (0.252" diameter, 0.075" height) and No. 2 Phillips drive. Manufactured to precise dimensional standards with RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance, ensuring environmental safety and regulatory adherence for industrial and commercial applications.
