S-90031A551 Length 3/8" Wood Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with black-oxide steel coating for long-lasting performance in various woodworking environments
• Superior holding power due to partial threading design that reduces wood splitting while maximizing grip in wood materials
• Flush, professional finish achieved through 82° countersink angle that allows screw heads to sit perfectly flush with wood surfaces
• Secure installation and reduced cam-out with Phillips No. 2 drive that provides reliable torque transfer during driving
• Optimized for both hardwood and softwood applications with specific drill bit size recommendations (5/64" for hardwood, 1/16" for softwood)
• Thread-forming design creates strong, permanent threads in wood without pre-tapping requirements
• Environmental compliance assurance with RoHS 3 and REACH regulations for safe, sustainable manufacturing

Professional Applications & Engineering Value

These No. 6 wood screws are engineered to address common woodworking challenges where splitting, corrosion, and improper seating compromise project integrity. The black-oxide steel construction provides essential protection against moisture and environmental exposure, while the thread forming design creates permanent, secure fastening without the need for pre-tapped holes. The partially threaded configuration concentrates holding power where it's needed most, reducing stress on wood fibers and minimizing splitting in both hardwood and softwood applications. The 82° countersink angle ensures professional, flush finishes in cabinetry, furniture assembly, and trim work, while the Phillips drive offers reliable installation with standard tools. These features combine to deliver consistent performance in demanding woodworking environments where fastener reliability directly impacts project longevity.

Specification Summary & Compliance

These wood screws feature a 0.138" thread diameter with 18 threads per inch in a right-hand thread direction, manufactured to precise dimensional standards for consistent performance. The partially threaded design provides optimal holding characteristics with a minimum thread length of 1/4". Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures these fasteners meet current industry standards for hazardous substance restrictions and chemical safety protocols.
