S-90031A221 Length 3/4" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for long-lasting performance in various environments
• Excellent holding power through thread forming design that creates strong, permanent threads in wood materials
• Flush, professional finish with 82° countersink angle and flat head design that sits perfectly with wood surfaces
• Secure installation provided by Phillips No. 2 drive that prevents cam-out and ensures proper torque transmission
• Versatile wood compatibility with specific drill bit recommendations for both hardwood (7/64") and softwood (5/64") applications
• Optimized thread engagement through partial threading that concentrates holding power where needed most
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe, environmentally responsible manufacturing

Professional Applications & Engineering Value

These No. 9 zinc-plated steel wood screws deliver exceptional engineering value through their thread forming design that eliminates the need for pre-tapped holes while creating superior pull-out resistance. The 14 TPI thread pitch provides optimal bite in both hardwood and softwood applications, preventing material splitting while ensuring maximum holding strength. The Phillips flat head configuration with standard profile allows for seamless countersinking at 82 degrees, creating professional-grade finishes in furniture manufacturing, cabinetry, and structural wood assemblies. The partially threaded shank concentrates gripping power at the critical engagement zone while reducing installation torque requirements. These wood screws are engineered to solve common woodworking challenges including material separation, screw back-out, and surface protrusion issues.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2A thread tolerances, these wood screws feature a right-hand thread direction with 0.177" diameter and 3/4" length. The thread forming tapping method ensures reliable performance without pre-threading requirements. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmentally responsible manufacturing and safe usage across professional woodworking applications.
