Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments and chemical exposure.
- Exceptional thread precision with Class 3A fit and UNF fine threads for secure, vibration-resistant fastening and minimal backlash.
- High mechanical strength and durability provided by Rockwell B80 hardness, ensuring long-term performance under load.
- Secure, non-slip installation enabled by the headless hex drive design and 1/4" drive size for easy torque application in confined spaces.
- Effective grip and component positioning due to the cup point tip, which bites into surfaces to prevent loosening.
- Compliance with major industry standards including ASME B18.3, ensuring dimensional accuracy and reliability in demanding applications.
- Environmentally safe and regulated material use with RoHS 3 and REACH compliance, meeting global environmental and safety directives.
Professional Applications & Engineering Value
This 316 stainless steel set screw is engineered to address critical challenges in precision assembly and machinery. Its headless hex design and fine UNF threading with a Class 3A fit provide exceptional holding power in high-vibration settings, such as automotive, aerospace, and marine equipment. The cup point tip ensures firm contact and resistance to rotational forces, while the material’s inherent corrosion resistance makes it suitable for outdoor, chemical, and sanitary applications. By combining Rockwell B80 hardness with strict adherence to ASME B18.3, this fastener delivers reliable, long-lasting performance in assemblies where failure is not an option, reducing maintenance needs and downtime.
Specification Summary & Compliance
This set screw features a 1/2"-20 UNF fine thread with Class 3A thread fit for high precision, a length of 1/2", and a right-hand thread direction. It is manufactured in compliance with ASME B18.3 specifications and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring both dimensional accuracy and material safety for industrial use.
