Professional Applications & Engineering Value
This 10-32 UNF Class 3A set screw is engineered to address critical challenges in precision assembly and machinery. The zinc plated alloy steel construction combats corrosion in harsh industrial settings, while the fine UNF threads and Class 3A fit ensure minimal backlash and superior vibration resistance in high-speed equipment. The headless design with hex drive allows installation in tight spaces, making it ideal for securing collars, gears, and pulleys on shafts. Its cup tip provides concentrated contact pressure, preventing axial movement in dynamic applications. Commonly used in automotive, aerospace, and manufacturing assemblies, this set screw delivers reliable clamping force and long-term performance under repetitive stress.
Specification Summary & Compliance
This set screw features a 10-32 UNF fine thread with Class 3A tolerance for precise fit, a length of 1/2", and a 3/32" hex drive. Manufactured from zinc plated alloy steel with a hardness of Rockwell C45, it meets ASME B18.3 and ASTM F912 specifications. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global industrial markets.
