S-91555A102 Length 1/2" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black phosphate steel coating, extending screw life in various woodworking environments
• Enhanced holding power through thread forming technology that creates strong, permanent threads in fiberboard and particleboard
• Optimized material engagement with partial threading design that reduces splitting while maintaining maximum grip strength
• Secure installation with Phillips No. 2 drive system that prevents cam-out and ensures proper torque application
• Reduced material stress thanks to the rounded pan head design that distributes pressure evenly without sinking
• Precision compatibility with standard 5/64" drill bits for clean, accurate installations every time
• Versatile application range with right-hand threading that works efficiently across various wood composite materials

Professional Applications & Engineering Value

These No. 8 wood screws are specifically engineered to address common challenges in fiberboard and particleboard applications where traditional fasteners often cause material splitting or strip out. The black phosphate steel construction provides essential corrosion protection for interior woodworking projects, while the thread forming technology eliminates the need for pre-tapped holes by displacing material to create strong, permanent threads. The partially threaded design ensures maximum holding power while minimizing stress on delicate wood composites. With a Phillips pan head and precise 0.164" thread diameter, these screws deliver reliable performance in cabinetry, furniture assembly, and construction applications where material integrity is paramount.

Specification Summary & Compliance

These wood screws feature precision Class 2A thread tolerances with 8 threads per inch and right-hand threading conforming to industry standards. The 0.322" head diameter and 1/2" length provide consistent dimensional accuracy for repeatable installations. Manufactured to meet quality fastening specifications for woodworking applications, these screws are compatible with standard 5/64" drill bits (0.078" diameter) and comply with relevant industrial fastener standards for material composition and performance requirements.
