• External hex drive design provides excellent torque transmission for quick installation with common tools
• Full threading along the 1" length offers maximum grip and adjustment flexibility in various materials
• Rockwell B70 hardness rating maintains thread integrity and prevents stripping during repeated use
• Compliance with major industry standards including ASME B18.2.1 ensures dimensional consistency and interoperability

Professional Applications & Engineering Value

This 3/8"-16 UNC hex head screw in 316 stainless steel delivers exceptional value in demanding industrial applications where corrosion resistance and mechanical strength are critical. The coarse thread design prevents cross-threading in high-vibration environments while providing faster installation compared to fine-thread alternatives. With its external hex drive and fully threaded configuration, this fastener offers superior clamping force distribution across the entire 1" length, making it ideal for structural assemblies, heavy machinery, and chemical processing equipment. The combination of 70,000 PSI tensile strength and Rockwell B70 hardness ensures long-term reliability in applications subject to dynamic loads and thermal cycling.

Specification Summary & Compliance

This hex head screw features 3/8"-16 UNC coarse threading with Class 2A thread fit tolerances per ASME B18.2.1 specifications. The inch-system fastener maintains precise dimensional accuracy with 0.375" thread diameter and right-hand thread direction. Manufacturing compliance includes ASME B18.2.1 for dimensional standards, RoHS 3 (2015/863/EU) for hazardous substance restrictions, and REACH (EC 1907/2006) for chemical safety regulations, ensuring global regulatory acceptance for industrial applications.
