Professional Applications & Engineering Value

This zinc-plated steel rounded head screw delivers exceptional engineering value through its combination of 60,000 psi tensile strength and Rockwell B69 hardness, making it ideal for heavy-duty industrial applications where structural integrity is paramount. The UNC coarse threading with Class 2A fit ensures rapid installation and reliable performance in materials where fine threading might strip or fail. The fully threaded design provides maximum contact surface area, distributing stress evenly and preventing loosening under vibration. Commonly specified in machinery assembly, structural frameworks, and equipment manufacturing, this slotted drive screw offers a cost-effective solution without compromising on performance standards. The zinc plating provides essential corrosion protection, extending service life in environments exposed to moisture or chemical agents.

Specification Summary & Compliance

Manufactured to precise ASME B18.6.3 specifications, this fastener maintains dimensional accuracy with Class 2A thread fit tolerances for consistent performance. The 3/8"-16 UNC coarse thread configuration ensures proper engagement in various materials while the right-hand threading follows industry standards. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental safety and restricted substance adherence. The combination of 60,000 psi tensile strength and Rockwell B69 hardness validates mechanical performance for industrial fastening requirements.
