Professional Applications & Engineering Value

Engineered for precision positioning and secure fastening, this 10-24 UNC brass set screw solves critical challenges in industrial assembly. The Class 3A thread fit provides exceptional tolerance control, eliminating play in rotating components while the coarse thread spacing ensures rapid installation. The headless design with cup tip creates maximum clamping force without protruding, making it ideal for shaft collars, gears, and pulleys where space optimization is crucial. Brass material offers natural corrosion resistance in marine, plumbing, and electrical applications while preventing sparking in hazardous environments. The 3/32" hex drive accommodates standard tools while maintaining a low profile for confined assemblies.

Specification Summary & Compliance

This set screw features precise 10-24 UNC coarse threads with Class 3A fit tolerance per ASME standards. Manufactured to ASME B18.3 specifications with 1/2" length and 0.19" thread diameter. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The right-hand thread direction and inch system measurements ensure compatibility with North American industrial standards.
