Professional Applications & Engineering Value
This zinc-plated steel rounded head screw addresses critical industrial fastening challenges where corrosion resistance and structural integrity are paramount. The combination of 60,000 psi tensile strength and Rockwell B69 hardness ensures reliable performance in heavy machinery, structural assemblies, and manufacturing equipment. The UNC coarse threads provide excellent engagement in various materials while the slotted drive accommodates standard installation tools. Particularly valuable in outdoor applications or environments with moisture exposure, the zinc plating creates a protective barrier that significantly extends service life while maintaining ASME B18.6.3 dimensional standards for consistent quality across production runs.
Specification Summary & Compliance
Manufactured to precise Class 2A thread fit tolerances with UNC 3/8"-16 coarse threading and right-hand thread direction. This fully threaded fastener meets ASME B18.6.3 dimensional specifications and demonstrates compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The 1" length and 0.375" thread diameter maintain consistent dimensional accuracy for reliable performance in industrial assembly applications.
