Professional Applications & Engineering Value
This Grade 5 hex head screw delivers critical engineering value in industrial settings where vibration resistance and structural integrity are paramount. The zinc plated steel construction combats environmental corrosion while maintaining the 120,000 psi tensile strength required for heavy machinery, structural steel connections, and equipment assembly. The coarse UNC thread design prevents cross-threading and ensures reliable performance in soft metals and wood applications. With Rockwell C25 hardness and fully threaded design, this fastener distributes clamping force evenly, reducing stress concentration points that lead to joint failure in dynamic load conditions common in manufacturing, construction, and automotive industries.
Specification Summary & Compliance
This heavy-duty hex head screw features precise Class 2A thread fit with UNC coarse threading (1/2"-13) and meets ASME B18.2.1/SAE J429 specifications for dimensional accuracy and performance. The fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors. Manufactured to Grade 5 strength standards with right-hand threading and external hex drive configuration for standardized tool compatibility.
