Key Features & Benefits at a Glance
- Superior corrosion resistance thanks to 18-8 stainless steel construction, ensuring long-term reliability in harsh environments.
- Exceptional holding power with Class 3A thread fit, providing tighter tolerances and more secure fastening than standard classes.
- High-strength durability from Rockwell B80 hardness, resisting wear and deformation under heavy loads.
- Secure, flush installation with the headless and hex drive design, allowing for unobtrusive mounting in tight spaces.
- Enhanced grip and minimal surface damage due to the cup tip, which concentrates force for better component retention.
- Reliable fine threading (UNF 5/16"-24) offers increased adjustment precision and vibration resistance in dynamic applications.
- Broad industry compliance including ASME B18.3, RoHS 3, and REACH, ensuring safety and environmental standards are met.
Professional Applications & Engineering Value
Engineered for demanding industrial settings, this 18-8 stainless steel hex headless set screw delivers robust performance where corrosion resistance and high-strength fastening are critical. The Class 3A UNF fine thread ensures precise alignment and superior clamp load, reducing the risk of loosening in machinery, automotive assemblies, and precision equipment. Its headless design with a 5/32" hex drive allows for easy installation in confined areas, while the cup tip minimizes damage to shaft surfaces, preserving component integrity. Ideal for permanent or semi-permanent applications, this set screw meets ASME B18.3 standards, providing reliability in high-stress environments and enhancing overall assembly longevity.
Specification Summary & Compliance
This set screw features a 5/16"-24 UNF fine thread with Class 3A fit for high precision, a length of 2-1/2", and a cup tip design. It complies with ASME B18.3 manufacturing specifications and adheres to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring it is free from hazardous substances and suitable for global industrial use.
