S-90031A383 Length 4" Wood Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc-plated steel construction for long-lasting performance in various environments
• Superior holding power through thread forming technology that creates strong, permanent threads in wood materials
• Clean, flush installation with standard flat head design and 82° countersink angle for professional finishing
• Optimized wood compatibility with specific drill bit sizes for both hardwood (5/32") and softwood (9/64") applications
• Secure driving control with No. 3 Phillips drive that reduces cam-out and ensures proper installation torque
• Reduced splitting risk with partially threaded design that minimizes stress on wood fibers during installation
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe industrial and commercial use

Professional Applications & Engineering Value

These No. 16 wood screws are engineered to address common fastening challenges in wood construction and manufacturing. The zinc-plated steel construction provides essential corrosion protection, while the thread forming technology eliminates the need for pre-tapped holes, creating stronger thread engagement that resists pull-out and vibration loosening. The Phillips flat head design with 82° countersink angle ensures flush mounting in furniture, cabinetry, and structural wood applications. With specific drill bit recommendations for both hardwood and softwood, these screws prevent material splitting and ensure precise installation every time. The 4-inch length and partial threading provide optimal grip length for medium to heavy-duty wood fastening projects, making them ideal for professional woodworking, construction, and manufacturing applications where reliability and compliance matter.

Specification Summary & Compliance

These wood screws feature precision right-hand threads with approximately 9 threads per inch and 0.268" thread diameter, ensuring consistent performance across applications. The manufacturing follows standard inch system measurements with 2.667" minimum thread length on the 4" overall length. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming they're free from restricted hazardous substances. The standard flat head profile and pointed tip facilitate easy starting and proper seating in wood materials, while the round shank cross-section maintains structural integrity during installation.
