Professional Applications & Engineering Value
These Grade 5 hex head screws deliver critical engineering solutions for industrial assembly challenges where vibration resistance and structural integrity are paramount. The zinc plated steel construction provides essential corrosion protection in manufacturing facilities, construction sites, and heavy equipment applications. The 7/8"-9 UNC coarse thread configuration ensures rapid installation while maintaining secure fastening in materials where fine threads might strip or fail. With full threading along the 6" length, these external hex drive fasteners offer maximum adjustability and clamping force distribution, making them ideal for structural steel connections, machinery assembly, and infrastructure projects requiring high tensile strength and reliable performance under dynamic loads.
Specification Summary & Compliance
This hex head screw features precise Class 2A thread fit tolerances with UNC coarse threading (7/8"-9) and right-hand thread direction. Manufactured to ASME B18.2.1 and SAE J429 Grade 5 specifications, ensuring dimensional accuracy and mechanical properties. The fastener is RoHS 3 (2015/863/EU) Compliant for environmental responsibility and meets all specified hardness (Rockwell C25) and tensile strength (120,000 psi) requirements for industrial-grade applications.
