Professional Applications & Engineering Value

This 10-32 UNF Class 3A set screw is engineered to solve critical challenges in precision assembly and machinery. Manufactured from 18-8 Stainless Steel, it provides excellent resistance to rust and corrosion, making it a dependable fastener for applications exposed to moisture, chemicals, or outdoor elements. The fine thread spacing and tight Class 3A thread fit create a superior grip, preventing components from slipping or shifting under dynamic loads and vibration, which is crucial in automotive, aerospace, and industrial equipment. The headless design with a hex drive allows it to sit flush within a threaded hole, securing collars, gears, and knobs on shafts without interfering with adjacent parts. This combination of material properties and thread precision delivers a reliable, long-lasting fastening solution for high-stakes engineering applications.

Specification Summary & Compliance

This set screw adheres to the UNF (Unified National Fine) thread standard with a Class 3A tolerance for a high-precision, close-fit thread engagement. The manufacturing ensures dimensional accuracy for the 10-32 thread size and 1/8" length. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free of restricted hazardous substances and safe for industrial use.
