• Easy installation and removal in confined spaces using the 3/32" hex drive on the headless design.
• Secure component positioning with minimal surface damage thanks to the oval tip type.
• Guaranteed dimensional consistency and interchangeability by conforming to the ASME B18.3 standard.
• Safe for use in regulated industries with full compliance to RoHS 3 and REACH environmental directives.

Professional Applications & Engineering Value

This 10-32 UNF set screw is engineered to solve critical challenges in precision assembly and machinery. Made from 316 stainless steel, it offers outstanding resistance to chemicals and moisture, preventing failure in demanding applications like marine equipment, chemical processing, and food machinery. The headless design with a 3/32" hex drive allows for flush mounting in tight spaces, while the Class 3A thread fit and fine thread provide superior clamping force and resistance to loosening under vibration. The oval tip ensures a firm grip on shafts and collars without causing significant surface marring, making it a reliable choice for permanent positioning of gears, pulleys, and other components on rotating assemblies.
