Professional Applications & Engineering Value
This Grade 5 hex head screw delivers exceptional engineering value through its zinc plated steel construction and 1"-8 UNC coarse threading, specifically designed to address common industrial fastening challenges. The combination of 120,000 psi tensile strength and Rockwell C25 hardness ensures reliable performance in heavy machinery, structural steel connections, and equipment assembly where vibration resistance and load capacity are critical. The external hex drive facilitates efficient installation with standard tools, while the Class 2A thread fit provides optimal clearance for rapid assembly without compromising joint integrity. Ideal for construction, manufacturing, and automotive applications, this fully threaded fastener maintains consistent clamping force across its entire 4½" length, preventing joint failure in high-stress environments.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2A thread fit and UNC coarse thread profile ensuring compatibility with standard mating components. This fastener conforms to ASME B18.2.1 specifications and SAE J429 Grade 5 requirements for mechanical properties. The product is fully RoHS 3 (2015/863/EU) compliant and meets industry standards for inch-system fasteners with right-hand threading and external hex drive configuration.
