S-91555A122 Length 1 3/8" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance thanks to black-oxide steel coating, extending screw lifespan in various workshop environments
• Enhanced holding power in engineered wood through thread forming technology that creates stronger, more permanent connections in fiberboard and particleboard
• Reduced material splitting with partially threaded design that concentrates gripping force where needed most
• Secure installation control with No. 2 Phillips drive that prevents cam-out and ensures proper seating depth
• Optimized thread engagement with 11 threads per inch and 0.164" diameter providing maximum pull-out resistance
• Clean finished appearance with rounded pan head design that sits flush without countersinking
• Simplified installation process with compatible 5/64" drill bit size for precise pilot holes

Professional Applications & Engineering Value

These black-oxide steel wood screws are specifically engineered to address common challenges in fiberboard and particleboard applications where traditional fasteners often fail. The thread forming technology eliminates the need for pre-tapped holes while creating compression forces that significantly improve pull-out resistance in engineered wood materials. The partially threaded design prevents material splitting by allowing the unthreaded shank to act as a dowel, while the threaded portion delivers exceptional holding power. The Phillips drive system with No. 2 size provides reliable torque transfer during installation, reducing driver slippage and ensuring consistent seating depth. These features combine to create high-performance wood screws that maintain structural integrity in cabinetry, furniture manufacturing, and construction applications where engineered wood products are prevalent.
