Professional Applications & Engineering Value
This 3/4"-10 UNC Class 3A hex headless set screw delivers critical engineering solutions for demanding industrial applications. Manufactured from 18-8 Stainless Steel, it provides excellent corrosion resistance in manufacturing, machinery, and outdoor equipment where environmental exposure is a concern. The coarse thread spacing and Class 3A thread fit create superior holding power that effectively counters vibration-induced loosening in high-stress assemblies. The hex headless design allows for flush mounting in confined spaces while maintaining maximum torque transmission through the 3/8" drive. These features make it particularly valuable for permanent positioning of gears, pulleys, and collars on shafts where reliability and precision are paramount.
Specification Summary & Compliance
This set screw features 3/4"-10 UNC coarse threads with Class 3A thread fit for precision manufacturing tolerances. The 2-1/2" length and cup tip provide optimal engagement and surface contact. Manufacturing complies with ASME B18.3 specifications, ensuring dimensional accuracy and performance reliability. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting current environmental regulations for hazardous substances.
