S-90031A599 Length 4" Wood Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with black-oxide steel coating for longer service life in various environments
• Superior holding power through thread forming design that compresses wood fibers without pre-drilling in softwoods
• Reduced installation effort with pointed tip and partial threading for easier penetration and precise placement
• Secure fastening control with Phillips No. 2 drive that minimizes cam-out during high-torque applications
• Flush surface finish achieved with standard 82° flat head profile that sits perfectly countersunk in wood materials
• Optimized wood compatibility with specific drill bit recommendations for both hardwood (9/64") and softwood (7/64") applications
• Reliable industrial compliance meeting RoHS 3 and REACH environmental standards for safe usage

Professional Applications & Engineering Value

These No. 14 wood screws deliver exceptional engineering value through their specialized thread forming design and black-oxide steel construction. The partially threaded configuration with 2.666" thread length provides concentrated holding power where it matters most, while the unthreaded shank prevents wood splitting in demanding applications. The Phillips flat head drive system ensures secure installation without the need for specialized tools, making them ideal for high-volume wood assembly operations. With precise 10 threads per inch and 0.242" thread diameter, these screws create permanent, vibration-resistant connections in furniture manufacturing, construction framing, and outdoor wood structures where durability and corrosion resistance are critical performance factors.

Specification Summary & Compliance

Manufactured to exacting dimensional standards with right-hand threading and standard flat head profile featuring 82° countersink angle. The thread forming tapping method ensures consistent performance without chip removal in wood substrates. These screws maintain precise Class 2A thread tolerances and are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, providing assurance for industrial procurement requirements and sustainable manufacturing practices.
