Professional Applications & Engineering Value
These zinc-plated steel rounded head screws deliver exceptional engineering value for industrial assembly applications where corrosion resistance and mechanical reliability are paramount. The 10-24 UNC coarse thread configuration provides superior holding power in various materials while the partial threading design allows for precise clamping force distribution. The slotted drive style ensures compatibility with standard tools, reducing installation time and tooling costs. With 60,000 psi tensile strength and Rockwell B69 hardness, these fasteners maintain structural integrity in vibration-prone environments, making them ideal for machinery, equipment manufacturing, and heavy-duty assemblies where fastener failure is not an option.
Specification Summary & Compliance
This 2 1/2" rounded head screw features precise Class 2A thread fit tolerances with 10-24 UNC coarse threading and right-hand thread direction. Manufactured to ASME B18.6.3 specifications with partial threading extending to a minimum of 1 1/2". The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets.
