Professional Applications & Engineering Value
Engineered for demanding industrial environments, these Grade B7 steel hex head screws deliver exceptional performance in high-pressure and high-temperature applications. The 5/8"-11 UNC coarse thread configuration provides superior resistance to vibration loosening while enabling rapid installation in heavy machinery, structural steel connections, and pressure vessel assemblies. The partially threaded design concentrates the clamping force precisely where needed, preventing joint failure in critical load-bearing applications. With Rockwell C35 hardness and 125,000 psi tensile strength, these fasteners maintain integrity under extreme mechanical stress, making them ideal for petrochemical plants, power generation equipment, and industrial processing systems where reliability is paramount.
Specification Summary & Compliance
This hex head screw features precise Class 2A thread fit tolerances with UNC coarse threading (5/8"-11) in a right-hand thread direction. The fastener meets ASTM A193 specification requirements for high-temperature service and is manufactured from ASTM Grade B7 steel with dimensions including 2 1/4" total length, 1 1/2" thread length, and 3/4" grip length. The external hex drive (1 1/16" width) ensures compatibility with standard industrial tools for secure installation.
