Professional Applications & Engineering Value
This 5/16"-24 UNF Class 3A set screw is engineered to solve critical challenges in precision assembly and machinery. The 18-8 Stainless Steel material provides excellent resistance to rust and corrosion, making it suitable for applications in manufacturing, automotive, and electronics where environmental factors are a concern. The fine thread spacing and Class 3A thread fit deliver a tighter, more reliable connection that resists vibrational loosening, a common failure point in dynamic systems. The hex headless and extended tip design allows for flush mounting while improving grip on shafts and collars, ensuring components remain securely positioned. Meeting ASME B18.3 specifications, this screw guarantees consistency and performance in high-stakes industrial settings, from conveyor systems to precision instruments.
Specification Summary & Compliance
This set screw features a 5/16"-24 UNF thread with a Class 3A fit for high precision and a fine thread spacing.
