S-91555A124 Length 1 5/8" Wood Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with black-oxide steel coating for long-lasting performance in demanding environments
• Superior holding power in fiberboard and particleboard through specialized thread forming technology
• Reduced installation effort with Phillips drive design ensuring secure tool engagement and efficient driving
• Optimized material integrity with partial threading that maintains maximum screw strength while preventing wood splitting
• Precise fastening alignment thanks to pointed tip design that facilitates accurate screw placement
• Reliable thread engagement with 11 threads per inch providing excellent grip in composite wood materials
• Simplified installation process with compatible 5/64" drill bit size for quick and accurate pilot hole preparation

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 struggle with material density variations. The thread forming technology creates precise mating threads without removing material, significantly reducing the risk of strip-out in composite wood substrates. The partial threading design concentrates holding power where it's needed most while maintaining shank strength, preventing joint failure under stress. The pan head configuration provides a low-profile finish that sits flush with material surfaces, making these No. 8 screws ideal for furniture assembly, cabinet installation, and construction projects requiring reliable fastening in engineered wood products.

Specification Summary & Compliance

These wood screws feature No. 8 thread diameter (0.164") with 11 threads per inch and right-hand threading conforming to standard inch measurement specifications. The 1.088" minimum thread length ensures consistent engagement depth, while the partially threaded design maintains structural integrity. Manufactured from steel with black-oxide surface treatment for enhanced durability, these fasteners are engineered for optimal performance with 5/64" (0.078") drill bits for proper pilot hole preparation in woodworking applications.
