Key Features & Benefits at a Glance
- Superior holding power with Class 3A thread fit for reliable, vibration-resistant fastening in critical assemblies.
- Exceptional durability from Rockwell C45 hardness alloy steel, resisting wear and deformation under high stress.
- Enhanced corrosion resistance with zinc plating, extending service life in harsh industrial environments.
- Secure, flush installation thanks to the headless hex drive design, ideal for confined spaces and rotating components.
- Precise torque application with the 3/32" hex drive, reducing the risk of tool slippage and fastener damage.
- Effective grip on shafts and collars using the cup tip, which minimizes surface marring while providing strong axial retention.
- Global compliance assurance meeting ASME B18.3, RoHS 3, and REACH standards for safe, regulated use in international markets.
Professional Applications & Engineering Value
This 10-32 UNF set screw is engineered to address common industrial challenges such as component slippage, vibration-induced loosening, and space constraints. The fine thread (UNF) and Class 3A fit provide tighter tolerances and increased thread engagement, crucial for maintaining precise alignment in machinery, automotive, and aerospace assemblies. Manufactured from zinc plated alloy steel, it offers a robust solution for securing pulleys, gears, and knobs on shafts, where the headless hex drive and cup tip ensure a flush finish and concentrated clamping force. Its Rockwell C45 hardness ensures it withstands repeated adjustments without stripping, making it a reliable choice for high-duty-cycle applications.
Specification Summary & Compliance
This set screw adheres to inch system dimensions: 10-32 UNF fine thread with a diameter of 0.19", length of 5/16", and a Class 3A thread fit for precision assembly. It conforms to ASME B18.3 manufacturing specifications and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring it is free from hazardous substances and suitable for global supply chains.
