- Exceptional holding power from Rockwell C45 hardness, preventing loosening under vibration and heavy loads
- Precise thread engagement with Class 3A fit, ensuring reliable fastening and reduced assembly errors
- Easy installation and removal using standard 3/32" hex drive tools, saving maintenance time
- Enhanced grip and positioning with extended tip design, improving component alignment in machinery
- Broad compliance with ASME B18.3, RoHS 3, and REACH standards, meeting global industrial and environmental requirements
- Space-saving headless design ideal for compact assemblies where protruding fasteners are not feasible
Professional Applications & Engineering Value
This 10-32 UNF set screw is engineered to address critical challenges in industrial fastening, such as vibration-induced loosening and corrosion in demanding environments. The Black Oxide Alloy Steel construction provides a durable barrier against moisture and chemicals, while the Class 3A thread fit and fine thread spacing deliver precise torque transmission and minimal backlash. The extended tip configuration enhances grip on shafts and collars, making it ideal for securing gears, pulleys, and couplings in machinery, automotive, and aerospace applications. Its headless design and hex drive allow for flush mounting and easy access in confined spaces, reducing assembly time and improving overall system reliability.
Specification Summary & Compliance
This set screw features a 10-32 UNF thread with Class 3A fit for high precision, a length of 3/4", and an extended tip with diameter of 0.127" and length of 0.049" (tolerances: -0.007" to 0 for diameter, -0.005" to 0 for length). It complies with ASME B18.3 manufacturing specifications, RoHS 3 (2015/863/EU) for restricted substances, and REACH (EC 1907/2006) for chemical safety, ensuring reliability and environmental responsibility in industrial use.
