Professional Applications & Engineering Value
Engineered for heavy machinery assembly and structural steel connections, this Grade 5 hex head screw addresses critical challenges in vibration resistance and long-term joint integrity. The zinc-plated steel construction provides essential corrosion protection for outdoor equipment and manufacturing facilities, while the flanged design eliminates need for separate washers, reducing component count and installation time. With coarse UNC threads maintaining holding power in high-vibration environments and fully threaded shank accommodating varying material thicknesses, this fastener delivers reliable performance in construction, agricultural equipment, and industrial maintenance applications where 110,000 psi tensile strength is required for safety-critical connections.
Specification Summary & Compliance
Manufactured to IFI 111/SAE J429 specifications with Class 2A thread fit ensuring dimensional accuracy and interchangeability. The 5/8"-11 UNC coarse thread maintains consistent engagement while Rockwell C22 hardness provides optimal balance between strength and ductility. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for unrestricted use in international markets. Right-hand thread direction and external hex drive conform to industrial standards for tool compatibility.
