Key Features & Benefits at a Glance
- Enhanced corrosion resistance and reduced light reflection with black-oxide coating, ideal for industrial environments.
- Superior thread engagement and vibration resistance due to Class 3A fine UNF threads, ensuring reliable, long-term fastening.
- High tensile strength and durability from alloy steel with Rockwell C45 hardness, preventing deformation under heavy loads.
- Secure, non-slip installation and removal with a 3/32" hex drive, allowing precise torque application in confined spaces.
- Effective anti-rotation locking through serrations that bite into mating surfaces, minimizing loosening in dynamic applications.
- Concentrated holding force from the cup tip design, providing deep penetration and firm grip on shafts or components.
- Broad compliance with industry standards including ASME B18.3, RoHS 3, and REACH, ensuring safety and environmental responsibility.
Professional Applications & Engineering Value
This 10-32 UNF Class 3A set screw is engineered to address common industrial challenges like component slippage and vibration-induced loosening. Made from black-oxide alloy steel, it offers excellent resistance to wear and mild corrosion, extending service life in machinery, automotive, and aerospace assemblies. The fine thread spacing and Class 3A thread fit provide tight tolerances for secure fastening in precision equipment, while the hex headless design with serrations ensures flush mounting and reliable locking without protruding parts. Ideal for securing gears, pulleys, and collars, this screw delivers consistent performance in high-stress environments, reducing maintenance needs and downtime.
Specification Summary & Compliance
This set screw adheres to ASME B18.3 specifications, with a Class 3A thread fit for precise dimensional accuracy and UNF fine threads (10-32 size). It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances. The manufacturing process guarantees consistent Rockwell C45 hardness and right-hand threading for reliable industrial use.
