S-91555A119 Length 7/8" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide steel coating for extended service life in demanding environments
• Enhanced torque transmission through Phillips No. 2 drive design prevents cam-out and driver slippage
• Optimal material displacement with thread forming technology creates stronger, more secure connections in fiberboard and particleboard
• Maximum holding power achieved through fully threaded 7/8" length with 11 TPI configuration
• Streamlined installation process using standard 5/64" drill bit for precise, consistent pilot holes
• Reduced surface damage with rounded pan head design that sits flush without splitting material
• Reliable fastening performance with pointed tip for easy starting and right-hand threading for standard installation

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 tapping by displacing material rather than removing it, creating stronger thread engagement that resists pull-out in low-density substrates. The combination of fully threaded design and precise 11 TPI configuration ensures maximum surface contact along the entire fastener length, distributing load evenly to prevent material cracking. The Phillips drive system provides reliable torque transfer during installation, while the black-oxide finish offers corrosion protection for interior applications where moisture resistance is required. These engineering features make them ideal for furniture manufacturing, cabinet installation, and construction projects requiring durable connections in engineered wood products.

Specification Summary & Compliance

These No. 8 wood screws feature precision 0.164" thread diameter with 11 threads per inch and 7/8" length meeting standard inch system specifications. The thread forming design follows established fastening principles for engineered wood materials. Manufacturing complies with industry standards for dimensional accuracy, including proper head diameter (0.322") and pan head profile specifications. The black-oxide steel construction provides consistent performance while meeting practical requirements for commercial and industrial woodworking applications.
