- High installation torque capability with a hex drive (5/32") design, allowing for easy and firm tightening in confined spaces.
- Enhanced grip and positioning from the extended tip (0.164" length), providing better component alignment and resistance to slippage.
- Consistent mechanical strength with Rockwell B80 hardness, offering dependable performance under repetitive stress.
- Space-saving headless design for flush mounting in applications where protrusion is not acceptable.
- Reliable compliance with industry standards, including ASME B18.3, for assured quality and interchangeability.
Professional Applications & Engineering Value
This 18-8 Stainless Steel set screw is engineered to address common industrial challenges such as component misalignment and vibration-induced loosening. The UNF Class 3A fine threads provide exceptional clamping force and precision fit, essential for machinery, automotive assemblies, and precision instruments where minimal backlash is critical. The extended tip design enhances contact surface area, improving grip on shafts or hubs and reducing the risk of damage to soft materials. Made from corrosion-resistant stainless steel, it ensures longevity in moist or chemically exposed environments, while the hex drive allows for high-torque installation without stripping. Ideal for securing gears, pulleys, and collars, this set screw delivers reliable performance in demanding industrial applications, supported by its compliance with key regulations.
Specification Summary & Compliance
This set screw features a 5/16"-24 UNF thread with Class 3A fit for high precision and strength. It adheres to ASME B18.3 manufacturing standards, ensuring dimensional accuracy and reliability. The product is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances and suitable for global industrial use.
