Professional Applications & Engineering Value
This Grade 5 hex head screw delivers exceptional engineering value through its zinc plated steel construction and 5/8"-11 UNC coarse thread configuration. The combination of 120,000 psi tensile strength and Rockwell C25 hardness addresses critical challenges in heavy machinery, structural steel connections, and industrial equipment assembly where vibration resistance and load distribution are paramount. The fully threaded design ensures maximum surface contact for superior clamping force, while the external hex drive facilitates high-torque installation without stripping. This fastener solves common industrial pain points including joint relaxation, corrosion-induced failure, and installation inefficiency, making it ideal for construction, manufacturing, and mechanical applications requiring durable, high-performance fastening solutions.
Specification Summary & Compliance
Manufactured to precise Class 2A thread fit tolerances with 5/8"-11 UNC coarse thread specifications. Complies with ASME B18.2.1 and SAE J429 Grade 5 standards for dimensional accuracy and mechanical properties. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements for environmental safety and substance restrictions.
