Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 stainless steel construction for extended service life in harsh environments
- High-strength performance delivering 70,000 psi tensile strength for reliable heavy-duty applications
- Optimized thread engagement with Class 2A fit and UNC coarse threads for faster assembly and reduced cross-threading
- Enhanced drive stability through external hex design providing secure tool engagement and torque transmission
- Partial threading design allowing precise clamping control where full thread engagement isn't required
- Industry compliance assurance meeting ASME B18.2.1 specifications for dimensional accuracy and performance
- Environmental regulation compliance with RoHS 3 and REACH certification for global manufacturing applications
Professional Applications & Engineering Value
This 1/4"-20 UNC hex head screw delivers exceptional engineering value through its 316 stainless steel composition and coarse thread design. The material's superior corrosion resistance addresses critical failure points in marine, chemical processing, and outdoor applications where moisture and corrosive elements compromise fastener integrity. The external hex drive provides maximum torque capability for high-tension assemblies, while the partially threaded configuration allows for precise unthreaded shank sections where shear strength is paramount. With 70,000 psi tensile strength and Rockwell B70 hardness, this 6" industrial hex screw maintains structural integrity under sustained loads, vibration, and thermal cycling common in heavy machinery, structural frameworks, and industrial equipment manufacturing.
Specification Summary & Compliance
This fastener maintains Class 2A thread fit tolerance per UNC standards with 1/4"-20 coarse thread specification and 3/4" minimum thread length. Manufacturing complies with ASME B18.2.1 dimensional and mechanical requirements. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) certifications, ensuring restricted substance compliance for global industrial applications.
