Key Features & Benefits at a Glance
- Superior corrosion resistance with black-oxide coating extends service life in demanding industrial environments
- Exceptional holding power achieved through Class 3A thread fit precision for secure, vibration-resistant fastening
- Optimized torque transmission via 3/32" hex drive design prevents tool slippage and damage during installation
- Enhanced material durability with Rockwell C45 hardness maintains structural integrity under heavy loads
- Reliable component positioning through cup tip design provides positive contact and prevents work surface damage
- Industry-standard compatibility with UNC coarse threads ensures easy replacement and broad application use
- Space-saving headless construction allows for flush mounting in confined assembly spaces
Professional Applications & Engineering Value
This 10-24 UNC set screw delivers critical engineering solutions for industrial applications requiring precise component positioning and secure fastening. The black-oxide alloy steel construction provides essential corrosion protection while maintaining the Rockwell C45 hardness needed for high-stress environments. The headless design with hex drive enables installation in tight spaces where conventional fasteners cannot operate, while the cup tip ensures maximum contact pressure without damaging shaft surfaces. Particularly valuable in machinery assembly, automotive components, and precision equipment, this set screw addresses common challenges of vibration loosening, space constraints, and corrosion-induced failure through its optimized coarse thread spacing and protective surface treatment.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with precision Class 3A thread fit ensuring consistent performance and interchangeability. The 10-24 UNC thread form with coarse spacing and right-hand direction follows industry standards for reliable engagement. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting international requirements for hazardous substance restrictions. The combination of 0.19" thread diameter and 1/4" length provides optimal dimensional stability for various industrial fastening applications.
