Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction for long-lasting performance in demanding environments
- Enhanced torque transmission through external hex head design preventing cam-out during high-torque applications
- Secure wood fastening with thread forming technology that creates stronger, vibration-resistant connections
- Optimized length-to-diameter ratio (5" length, 3/8" diameter) provides exceptional holding power in heavy wood applications
- Reduced splitting risk with partially threaded shank design that minimizes stress concentration in wood materials
- Industry-standard compatibility ensuring reliable performance across various wood fastening applications
- Environmental compliance meeting strict RoHS 3 and REACH regulations for safe industrial use
Professional Applications & Engineering Value
These zinc-plated steel hex head wood screws are engineered to address critical challenges in industrial wood fastening applications. The thread forming technology eliminates the need for pre-drilling in many scenarios, creating permanent threads in wood that resist loosening under vibration and load cycles. The external hex drive system delivers maximum torque transmission for high-clamp force applications in construction, timber framing, and heavy-duty wood assemblies. With a substantial 3/8" diameter and 5" length, these screws provide exceptional shear strength and pull-out resistance, making them ideal for structural connections, pallet manufacturing, and outdoor wood structures where environmental exposure demands corrosion-resistant zinc plating.
Specification Summary & Compliance
Manufactured to ASME B18.2.1 standards with Class 2A thread tolerances, these wood screws feature 0.375" thread diameter, 7 threads per inch, and 3" minimum thread length. The partially threaded design with pointed tip facilitates easier starting and reduced wood splitting. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and regulatory acceptance for industrial procurement.
