Professional Applications & Engineering Value
This 10-32 UNF Class 3A brass set screw is engineered to address common challenges in precision assembly and maintenance. The fine thread spacing and Class 3A thread fit provide a tight, secure connection that resists loosening from vibration, making it ideal for machinery, automotive, and electronics applications. The headless design and compact 1/8" length allow for flush mounting in space-constrained components. The cup point tip bites into the shaft material, ensuring positive locking without damaging the surface. Made from brass, it offers excellent electrical conductivity and corrosion resistance, which is critical in electrical enclosures and marine environments. This set screw delivers reliable performance where precision and durability are paramount.
Specification Summary & Compliance
This set screw features a 10-32 UNF thread with a Class 3A tolerance for high precision and a fine thread spacing. The thread diameter is 0.19" with a length of 1/8". It is manufactured in accordance with ASME B18.3 standards and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent environmental and safety requirements for industrial use.
