Professional Applications & Engineering Value

These No. 8 wood screws with Black-Oxide Steel construction address critical challenges in wood fastening applications. The thread forming design eliminates the need for separate tapping operations while creating stronger, more vibration-resistant connections in both hardwood and softwood materials. The partially threaded configuration provides optimal clamping force distribution, preventing wood splitting and ensuring consistent performance across varying densities. With precise 82° countersink angle and flat head profile, these screws deliver flush finishes in furniture manufacturing, cabinetry, and structural wood assemblies. The Phillips drive system with No. 2 size ensures reliable torque transfer during high-volume installation, reducing driver slippage and improving production efficiency in industrial woodworking environments.

Specification Summary & Compliance

These wood screws feature precision 0.164" thread diameter with 15 threads per inch and minimum thread length of 0.333" for consistent fastening performance. The inch system measurement ensures compatibility with North American standards and tooling. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and regulatory acceptance for industrial distribution. The standard flat head profile and right-hand threading conform to industry-accepted specifications for wood fastening applications.
