- Superior strength and durability from black-oxide alloy steel construction with Rockwell C45 hardness rating
- Precise thread engagement with Class 3A thread fit ensuring reliable performance in demanding applications
- Easy installation and removal with 3/32" hex drive design in headless configuration for space-constrained applications
- Excellent corrosion resistance from black-oxide surface treatment protecting against industrial environments
- Secure component positioning with cup point design providing maximum holding power and resistance to loosening
- Industry-standard compatibility with UNC coarse thread pattern for broad application across equipment and machinery
Professional Applications & Engineering Value
This 10-24 UNC set screw delivers exceptional engineering value for industrial applications requiring reliable component fixation. The black-oxide alloy steel construction combined with Rockwell C45 hardness provides superior resistance to wear and deformation under load. The integrated nylon patch thread locker effectively prevents loosening caused by vibration, a common failure point in rotating machinery and equipment. The cup point design creates positive seating and maximum holding power on shafts, collars, and pulleys. With Class 3A thread fit precision and coarse thread spacing, this fastener ensures quick assembly and disassembly while maintaining secure fastening in high-vibration environments from automotive assemblies to industrial machinery.
Specification Summary & Compliance
This set screw features Class 3A thread fit with UNC coarse thread pattern, 10-24 thread size, and 1/2" length. Manufactured to ASME B18.3 specifications with Rockwell C45 hardness rating. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international environmental and safety standards for industrial use.
