S-91555A117 Length 3/8" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide coating for extended service life in various workshop environments
• Enhanced thread engagement through thread forming technology creates stronger, more permanent connections in wood composites
• Optimized driving efficiency with Phillips No. 2 drive design prevents cam-out and ensures secure installation
• Maximum holding power achieved through full threading along the entire 3/8" length for superior grip in fiberboard and particleboard
• Precision compatibility with No. 49 drill bit (0.073" diameter) ensures proper pilot hole sizing for optimal performance
• Reduced material splitting thanks to pointed tip design that guides the screw smoothly into wood composite materials
• Professional appearance with rounded pan head style that sits flush against material surfaces

Professional Applications & Engineering Value

These black-oxide steel wood screws are specifically engineered to address common challenges in fiberboard and particleboard applications where material integrity and holding strength are critical. The thread forming technology creates precise mating threads without removing material, significantly reducing the risk of strip-out in composite wood products. With a 0.151" thread diameter and 12 TPI configuration, these screws provide optimal thread density for maximum pull-out resistance in engineered wood materials. The Phillips No. 2 drive system ensures reliable torque transfer during installation, while the fully threaded design guarantees consistent holding power along the entire fastener length. These features make them ideal for furniture manufacturing, cabinet installation, and other woodworking applications requiring dependable fastening solutions.
