Professional Applications & Engineering Value
Engineered for demanding industrial environments, these 316 stainless steel rounded head screws deliver exceptional performance where corrosion resistance and mechanical strength are paramount. The passivated finish creates a protective oxide layer that significantly enhances resistance to chlorides, acids, and industrial chemicals, making them ideal for chemical processing, marine equipment, and food-grade applications. With Class 3A thread fit and UNC coarse threading, these fasteners provide superior engagement in softer materials and vibration-prone assemblies. The combination of 70,000 psi tensile strength and Rockwell B55 hardness ensures reliable performance in structural applications while the 1/8" hex drive and rounded button head profile facilitate installation in confined spaces without compromising torque transmission.
Specification Summary & Compliance
This 10-24 UNC 3/4" rounded head screw features precision Class 3A thread fit with UNC coarse threading (0.19" diameter) and full threading along the 3/4" length. Manufactured to ASME B18.3 specifications and ASTM F879 standards, ensuring dimensional accuracy and consistent performance. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and material transparency for global industrial applications.
