S-91555A118 Length 5/8" Wood Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with thread forming technology that creates permanent, secure threads in fiberboard and particleboard
• Superior corrosion resistance thanks to the black-oxide steel finish that protects against environmental elements
• Optimized installation efficiency with Phillips No. 2 drive and pan head design for secure tool engagement and flush mounting
• Enhanced material integrity through thread forming action that compresses rather than removes material, reducing splitting
• Reliable holding power with fully threaded No. 8 (0.164") diameter design and 11 threads per inch for maximum grip
• Versatile application compatibility with standard 5/64" drill bit size for various woodworking and construction projects
• Consistent performance through precise 5/8" length and pointed tip design for accurate placement and penetration

Professional Applications & Engineering Value

These black-oxide steel wood screws are engineered specifically for fiberboard and particleboard applications where material integrity and holding strength are critical. The thread forming technology addresses common challenges in engineered wood products by compressing material fibers to create permanent threads without pre-drilling, significantly reducing installation time while preventing material splitting. The Phillips drive system with No. 2 size ensures secure tool engagement during high-torque applications, while the pan head design provides a low-profile finish suitable for various woodworking projects. These No. 8 wood screws deliver exceptional performance in furniture manufacturing, cabinet installation, and construction applications where reliable fastening in composite wood materials is essential.
