S-90031A172 Length 5/8" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in various woodworking environments
• Enhanced holding power through thread forming technology that creates strong, permanent threads without pre-tapping in wood materials
• Optimized material engagement with partial threading design that prevents wood splitting while maintaining maximum grip strength
• Efficient installation with Phillips No. 2 drive system providing reliable torque transfer and reduced cam-out during driving
• Clean professional finish featuring 82° countersink angle that allows the flat head to sit flush with wood surfaces
• Versatile wood compatibility with specific drill bit recommendations for both hardwood (3/32") and softwood (1/16") applications
• Reliable performance standards meeting industrial compliance requirements for safety and environmental regulations

Professional Applications & Engineering Value

These No. 7 wood screws are engineered to address common fastening challenges in wood construction and woodworking projects. The zinc-plated steel construction provides essential corrosion protection for both indoor and outdoor applications, while the thread forming technology creates superior holding power by compressing wood fibers rather than removing them. This approach eliminates the need for pre-tapped holes and significantly reduces the risk of wood splitting, particularly in delicate hardwoods. The Phillips flat head design with standard profile ensures clean, flush installations that maintain structural integrity. With right-hand threads and precise 16 TPI configuration, these screws deliver consistent performance in furniture assembly, cabinetry, deck building, and general construction applications where reliable fastening is critical.

Specification Summary & Compliance

These wood screws feature a 0.151" thread diameter with 16 TPI configuration and 0.417" minimum thread length for optimal engagement. The flat head design with 82° countersink angle ensures proper seating in wood surfaces. Manufactured to precise dimensional standards with thread forming tapping method and right-hand thread direction. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental and safety regulations for industrial use.
