Professional Applications & Engineering Value
Engineered for industrial machinery, equipment assembly, and metal fabrication, these zinc-plated steel rounded head screws address critical fastening challenges in high-vibration environments. The fully threaded UNC coarse spacing ensures maximum thread contact in both thin and thick materials, preventing loosening under dynamic loads. With Rockwell B70 hardness and Class 2A thread fit, these Phillips/slotted drive screws maintain dimensional stability while the zinc plating provides sacrificial protection against corrosion. The rounded head profile eliminates sharp edges for safer handling and cleaner installations in automotive, electrical enclosures, and general manufacturing applications where reliability and regulatory compliance are paramount.
Specification Summary & Compliance
This 10-24 x 3/8" screw features UNC coarse threads with Class 2A tolerance for precise fitment. Manufactured to ASME B18.6.3 specifications with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The right-hand thread direction and fully threaded design ensure consistent performance across standard industrial applications.
