- High durability with Rockwell B55 hardness providing excellent wear resistance and thread integrity
- Secure cup tip design creates positive locking action without damaging shaft surfaces
- Compact headless profile allows installation in confined spaces where standard screws won't fit
- Reliable hex drive system with 3/32" size enables high torque application and prevents stripping
- Industry compliance meets ASME B18.3 standards and environmental regulations for global applications
Professional Applications & Engineering Value
This 10-24 UNC brass set screw delivers exceptional engineering value in precision assembly applications where corrosion resistance and reliable positioning are critical. The Class 3A thread fit provides tighter tolerances than standard commercial grades, ensuring minimal play in machinery components, electrical connectors, and precision instruments. The cup tip design creates concentrated point contact that securely locks collars, gears, and pulleys without marring shafts, while the headless configuration enables flush mounting in space-constrained assemblies. Manufactured from brass material, this set screw eliminates galvanic corrosion when used with dissimilar metals and maintains performance in humid, chemical, or marine environments where steel fasteners would degrade.
Specification Summary & Compliance
This precision set screw features 10-24 UNC coarse thread with Class 3A fit for superior thread engagement, measuring 1/4" in length with 0.19" thread diameter. The hex drive accepts 3/32" tools and the cup tip provides secure locking action. Manufactured to ASME B18.3 specifications and compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for use in restricted substance-sensitive applications.
