Professional Applications & Engineering Value
This zinc-plated steel slotted rounded head screw delivers exceptional value in industrial settings where corrosion resistance and high tensile strength are critical. The binding head style provides a wide bearing surface that prevents pull-through in softer materials while the UNC coarse thread offers superior resistance to vibration loosening. Engineered with full threading and Class 2A thread fit, this fastener ensures reliable performance in electrical panels, machinery assembly, and binding post applications where consistent clamping force and environmental compliance are essential. The combination of Rockwell B69 hardness and protective zinc plating makes it ideal for outdoor equipment, industrial controls, and manufacturing fixtures exposed to moderate environmental conditions.
Specification Summary & Compliance
This 1/4"-20 x 3/4" rounded head screw features precision UNC coarse threading with Class 2A thread fit tolerance for consistent engagement. Manufactured to meet ASME B18.6.3 specifications, ensuring dimensional accuracy and performance reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global industrial applications requiring strict regulatory adherence.
