Professional Applications & Engineering Value
These Grade 5 hex head screws deliver critical engineering value in heavy-duty applications where tensile strength and corrosion resistance are paramount. The zinc plated steel construction provides essential protection against environmental degradation in construction, manufacturing, and industrial assembly. The fully threaded UNC coarse design ensures maximum thread engagement in materials where vibration resistance and pull-out strength are concerns. With external hex drive compatibility, these screws offer superior torque transmission for secure installations in structural frameworks, machinery assembly, and equipment manufacturing. The 1/4-20 thread size and 5-inch length make them ideal for joining thicker materials where standard fasteners fall short.
Specification Summary & Compliance
Manufactured to precise Class 2A thread fit tolerances with UNC coarse threading for optimal performance. Complies with ASME B18.2.1 and SAE J429 manufacturing standards, ensuring dimensional accuracy and mechanical properties. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental compliance requirements. The Grade 5 classification guarantees consistent 120,000 psi tensile strength and Rockwell C25 hardness across all production batches.
