Professional Applications & Engineering Value
Engineered for precision locking applications, this 6-32 UNC set screw delivers reliable performance in industrial machinery, automation systems, and precision equipment. The black-oxide alloy steel construction provides enhanced corrosion protection while maintaining the Rockwell C45 hardness required for repeated adjustment cycles. The headless hex drive design allows flush mounting in tight spaces where conventional fasteners cannot be accommodated. The cup tip creates concentrated contact pressure, effectively securing shafts, collars, and pulleys against rotational forces. With its Class 3A thread fit, this fastener maintains precise tolerances for critical assemblies where vibration resistance is paramount, making it ideal for manufacturing, automotive, and aerospace applications demanding precision fasteners.
Specification Summary & Compliance
This set screw features 6-32 UNC coarse threads with Class 3A fit tolerances, 5/16" length, and 1/16" hex drive. Manufactured to ASME B18.3 specifications using alloy steel with black-oxide surface treatment. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global markets.
