Professional Applications & Engineering Value

These 3/8" x 4" Black Zinc-Plated Steel Wood Screws are engineered to address common challenges in wood construction and fabrication. The thread forming design eliminates the need for pre-drilling in many applications, creating stronger thread engagement by compressing wood fibers rather than removing them. This results in superior pull-out resistance and reduced material stress. The external hex drive system provides maximum torque capability, preventing stripping during high-torque applications common in structural wood assemblies. With partial threading and substantial 4" length, these screws deliver optimal clamping force distribution, making them ideal for heavy-duty wood framing, timber construction, furniture manufacturing, and outdoor wood structures where corrosion resistance and long-term reliability are critical.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2A thread tolerances, these wood screws feature a 3/8" diameter with 7 threads per inch configuration and 4" overall length. The product complies with ASME B18.2.1 mechanical and dimensional specifications, ensuring interchangeability and reliable performance. Environmental compliance is verified through RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) certifications, confirming the absence of restricted substances. The black zinc-plated surface treatment provides consistent corrosion protection while maintaining the structural integrity of the underlying steel material.
