Key Features & Benefits at a Glance
- Exceptional holding power with Class 3A thread fit ensures a precise, secure, and vibration-resistant connection in demanding assemblies.
- Superior corrosion resistance from the black-oxide finish on alloy steel extends the screw's service life in harsh industrial environments.
- High-strength durability with a Rockwell C45 hardness rating provides reliable performance and resistance to wear and deformation.
- Secure, flush mounting is enabled by the headless design and cup tip, preventing component interference and providing excellent grip.
- Easy and efficient installation with the 0.028" hex drive allows for high torque application in confined spaces.
- Reliable fine-thread engagement from the 0-80 UNF thread form offers superior clamping force and is less prone to loosening under stress.
- Guaranteed quality and safety through compliance with ASME B18.3, RoHS 3, and REACH standards for regulated industrial applications.
Professional Applications & Engineering Value
This 0-80 UNF set screw is engineered to solve critical challenges in precision assemblies. The black-oxide alloy steel construction provides a robust barrier against rust and corrosion, making it ideal for machinery, automotive, and electronics where environmental factors are a concern. The headless design and cup tip allow for a completely flush installation, essential for rotating components and space-constrained applications. Combined with the fine thread spacing and Class 3A thread fit, this screw delivers maximum clamping force and superior resistance to vibrational loosening, ensuring long-term reliability and reducing maintenance needs in high-stakes industrial environments.
Specification Summary & Compliance
This set screw features a 0-80 UNF thread with a Class 3A thread fit, ensuring high precision and interchangeability. It is manufactured to meet ASME B18.3 specifications where identified by ASTM F912. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming it is free of restricted hazardous substances for safe use in global markets.
