Professional Applications & Engineering Value

These 10-24 UNC zinc-plated steel rounded head screws deliver critical performance where corrosion resistance and mechanical reliability are paramount. The zinc-plated steel construction provides essential protection against environmental degradation in manufacturing facilities, outdoor equipment, and metal assemblies. With coarse UNC threading and Class 2A thread fit, these fasteners prevent cross-threading during high-volume assembly while maintaining secure connections in vibrating machinery. The pan head profile distributes clamping force effectively across joined materials, while the slotted drive ensures compatibility with standard screwdrivers for maintenance and field service. Engineered for industrial applications requiring 60,000 psi tensile strength, these screws withstand substantial mechanical stress without compromising joint integrity.

Specification Summary & Compliance

This 2" length screw features precision Class 2A thread fit with UNC coarse threading (10-24 size) and fully threaded design for maximum engagement. Manufactured to ASME B18.6.3 specifications for dimensional accuracy and performance consistency. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring responsible material sourcing and manufacturing practices for global industrial applications.
