Professional Applications & Engineering Value
This 10-24 UNC set screw delivers exceptional engineering value in precision mechanical systems where component positioning and security are critical. The black-oxide alloy steel construction provides excellent corrosion resistance while maintaining the Rockwell C28 hardness required for high-stress applications. The headless hex drive design enables installation in confined spaces, while the soft brass tip prevents damage to shafts, gears, and other precision components during clamping. Particularly valuable in manufacturing equipment, automotive assemblies, and precision instruments, this Class 3A thread fit ensures consistent clamping force without loosening under vibration, making it ideal for permanent positioning applications where reliability cannot be compromised.
Specification Summary & Compliance
This set screw features precision 10-24 UNC coarse threads with Class 3A thread fit for superior dimensional accuracy and engagement. Manufactured to ASME B18.3 specifications ensuring consistent quality and performance. 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. Thread diameter measures 0.19" with a total length of 3/4" and features a 3/32" hex drive for secure installation.
