S-91555A128 Length 3" Wood Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with black-oxide steel coating for extended service life in demanding woodworking environments
• Superior material penetration through thread forming technology that creates stronger, more permanent connections in fiberboard and particleboard
• Optimized installation efficiency with Phillips No. 2 drive that prevents cam-out and ensures consistent torque application
• Reduced material splitting through partial threading design that concentrates holding power where needed most
• Precise alignment and faster starts with pointed tip geometry that guides screws accurately using standard 5/64" drill bits
• Flush finishing capability with rounded pan head design that sits neatly against material surfaces without protruding
• Reliable performance in engineered woods specifically engineered for fiberboard and particleboard applications where traditional screws may fail

Professional Applications & Engineering Value

These black-oxide steel wood screws address critical challenges in modern woodworking and construction applications. The thread forming technology eliminates the need for pre-tapped holes while creating stronger molecular bonds in fiberboard and particleboard materials, which are prone to stripping with conventional screws. The partial threading design prevents material stress concentration, reducing the risk of splitting in engineered wood products. With Phillips No. 2 drive compatibility, installers benefit from widespread tool availability and reduced driver slippage during high-torque applications. The combination of 0.164" thread diameter and 11 threads per inch provides optimal bite in composite wood materials, ensuring reliable performance in cabinetry, furniture assembly, and structural wood applications where vibration resistance and long-term integrity are paramount.

Specification Summary & Compliance

Manufactured to precise dimensional standards with right-hand threading and 3" length specifications. Features standard inch system measurements with consistent 0.322" head diameter and 0.115" head height for uniform installation. The thread forming tapping method ensures reliable performance without requiring pre-threaded holes. Compatible with standard 5/64" drill bits (0.078" diameter) for precise pilot hole preparation. These screws meet industry standards for wood fastening applications and are manufactured using RoHS and REACH compliant materials and processes.
