S-90031A495 Length 5" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in various wood applications
• Enhanced holding power through thread forming design that creates strong, secure threads in wood without pre-tapping
• Easy installation and reduced cam-out with Phillips drive style, providing better torque transfer and driver control
• Clean, flush finish thanks to the standard flat head profile and 82° countersink angle for professional-looking wood projects
• Optimized for both hardwood and softwood with specific drill bit size recommendations (13/64" for hardwood, 11/64" for softwood)
• Reliable partial threading that allows for stronger clamping force while minimizing wood splitting
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe, sustainable manufacturing

Professional Applications & Engineering Value

These No. 20 wood screws are engineered specifically for demanding wood applications where maximum holding power and durability are critical. The zinc-plated steel construction provides excellent corrosion resistance, making them suitable for both indoor and outdoor wood projects. The thread forming design creates permanent, secure threads in wood without the need for pre-tapping, eliminating stripping and ensuring consistent performance. With a 0.32" thread diameter and 8 threads per inch, these screws deliver optimal grip in various wood densities. The Phillips flat head configuration allows for flush installation with minimal surface disruption, while the partially threaded shank provides superior pull-out resistance. Ideal for furniture assembly, construction framing, and cabinetry, these screws solve common wood fastening challenges including splitting, corrosion, and installation inefficiency.

Specification Summary & Compliance

These wood screws feature precision right-hand threads with standard inch measurements, including a 5" length and 0.32" thread diameter. The manufacturing follows industry standards for flat head profile with an 82° countersink angle and partially threaded design. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance adherence. The thread forming method provides consistent performance without requiring pre-tapped holes, making them suitable for various wood types with recommended drill sizes of 13/64" for hardwood and 11/64" for softwood applications.
