Professional Applications & Engineering Value

This 10-32 UNF Class 3A set screw delivers critical engineering value in applications requiring precise component alignment and resistance to loosening. Manufactured from 316 stainless steel, it addresses common failure points in corrosive settings—such as marine, chemical processing, and food machinery—by offering exceptional pitting and crevice corrosion resistance. The headless hex drive design with a 3/32" drive size enables compact assembly configurations while maintaining high torque capability. Combined with a fine thread and flat tip, it ensures maximum surface contact and clamping force, effectively solving vibration-induced displacement in pulleys, collars, and gears. Its compliance with ASME B18.3 guarantees dimensional consistency, making it a trusted choice for OEMs and maintenance teams in demanding industrial environments.

Specification Summary & Compliance

This set screw adheres to Class 3A thread fit tolerances per UNF standards, ensuring high precision in thread engagement. Manufacturing follows ASME B18.3 specifications for dimensional accuracy, including a 10-32 thread size, 3/8" length, and right-hand thread direction. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted hazardous substances. This makes it suitable for global supply chains and environmentally conscious industries.
