Professional Applications & Engineering Value
Engineered for precision, this 6-32 UNC zinc-plated steel rounded head screw addresses common industrial challenges such as component loosening and environmental degradation. The coarse thread design ensures excellent engagement in softer materials or pre-tapped holes, reducing the risk of cross-threading and speeding up assembly lines. With a Rockwell B69 hardness and zinc plating, it resists corrosion from moisture, chemicals, and outdoor exposure, making it ideal for electronics enclosures, machinery panels, and automotive fixtures. The fully threaded shank and slotted drive provide consistent clamping force and ease of adjustment, crucial for maintenance and repair operations where reliability is paramount.
Specification Summary & Compliance
This screw features a Class 2A thread fit for consistent dimensional accuracy and a 0.138" thread diameter with UNC coarse threading. It adheres to the ASME B18.6.3 standard for slotted head screws and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring no restricted hazardous substances are used. The right-hand thread direction and standard rounded head profile further support reliable performance in industrial fastener applications.
