Key Features & Benefits at a Glance
- Exceptional tensile strength of 125,000 PSI ensures reliable performance in demanding industrial environments.
- High hardness rating (Rockwell C35) provides superior resistance to wear and deformation under heavy loads.
- Partially threaded design offers optimal grip length control and prevents thread damage during installation.
- Coarse UNC threads with Class 2A fit deliver faster assembly and consistent clamping force in various materials.
- External hex drive configuration allows for high-torque installation using standard tools without stripping.
- ASTM A193 Grade B7 certification guarantees material quality and compliance with high-pressure/temperature applications.
- Precision inch-dimensioned geometry ensures seamless compatibility with existing industrial equipment and components.
Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, these Grade B7 steel hex head screws solve critical fastening challenges in high-stress environments. The partially threaded UNC coarse thread design prevents cross-threading while maintaining maximum clamping force in pressure vessels, structural steel connections, and machinery assemblies. With ASTM A193 certification and 125,000 PSI tensile strength, these external hex drive fasteners withstand extreme temperatures and pressures where standard fasteners fail. The Rockwell C35 hardness ensures thread integrity remains intact during repeated disassembly cycles, making them ideal for maintenance-intensive operations in petrochemical, power generation, and heavy equipment industries.
Specification Summary & Compliance
Manufactured to ASTM A193 Grade B7 specifications with Class 2A thread fit ensuring precise dimensional accuracy. The 3/8"-16 UNC coarse thread follows standardized inch system measurements with 1" thread length and 1 1/4" grip length. Complies with industrial standards for high-strength steel fasteners and meets material composition requirements for critical service applications.
