S-97196A117 Length 1 5/8" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for long-lasting performance in various environments
• Enhanced holding power through thread forming design that creates strong, permanent threads in fiberboard and particleboard
• Clean, flush installation with standard flat head profile and 82° countersink angle for professional-looking finishes
• Optimized driving efficiency with No. 2 Phillips drive that reduces cam-out and improves torque transfer
• Reduced material splitting through partial threading design that concentrates gripping power where needed most
• Precise installation guidance with recommended 5/64" drill bit size for proper pilot hole preparation
• Versatile right-hand threading compatible with standard driving tools and conventional installation methods

Professional Applications & Engineering Value

These zinc-plated steel wood screws are specifically engineered to address common fastening challenges in fiberboard and particleboard applications. The thread forming design eliminates the need for pre-tapped holes while creating strong, permanent threads that resist pull-out in softer composite wood materials. The 82° countersink angle ensures the flat head sits flush with the material surface, preventing snagging and creating smooth finishes ideal for furniture assembly, cabinet installation, and construction projects. The partial threading concentrates gripping power in the engagement zone while reducing the risk of material splitting in delicate wood composites. The corrosion-resistant zinc plating provides essential protection against environmental factors, making these Phillips flat head screws suitable for both interior and protected exterior applications where durability and professional results are paramount.
