Key Features & Benefits at a Glance
- Enhanced corrosion resistance with black-oxide steel coating, ideal for indoor wood applications requiring durability.
- Superior holding power in fiberboard and particleboard due to thread forming design that compresses material without pre-drilling in many cases.
- Clean, flush installation with 82° countersink angle and standard flat head profile for a smooth, professional finish.
- Efficient driving with reduced cam-out using Phillips No. 2 drive, ensuring secure torque application and faster assembly.
- Optimized thread engagement featuring 0.164" diameter and 11 threads per inch for strong pull-out resistance in engineered wood.
- Versatile partial threading allows unthreaded shank to act as a pilot, minimizing splitting in brittle materials.
- Precision compatibility with recommended 5/64" drill bit for accurate pilot holes, ensuring consistent performance.
Professional Applications & Engineering Value
These black-oxide steel wood screws are engineered to address common challenges in fiberboard and particleboard fastening, such as material splitting and weak grip. The thread forming tapping method displaces wood fibers rather than cutting them, creating a tighter fit that resists loosening under vibration or load. Combined with a pointed tip and partially threaded design, the screw guides smoothly into pre-drilled holes (using the specified 5/64" bit) while the unthreaded shank reinforces the joint. This makes them ideal for cabinet assembly, furniture manufacturing, and construction projects where high tensile strength and a flush flat head finish are critical for both aesthetics and safety.
Specification Summary & Compliance
Manufactured to standard inch system dimensions with precise head diameter tolerance of -0.04" and right-hand threading. The screws adhere to common industrial specifications for flat head wood screws, including consistent thread diameter of 0.164" and approximately 11 threads per inch. Compliant with RoHS and REACH environmental standards, ensuring safe use in various woodworking and construction applications without hazardous substances.
