Key Features & Benefits at a Glance
- Superior holding power with Class 3A thread fit ensuring precise, vibration-resistant connections in demanding applications.
- Enhanced corrosion resistance from the black-oxide finish, extending service life in harsh industrial environments.
- Maximum grip and minimal slippage thanks to the 90° cone point design that bites securely into mating surfaces.
- High-strength durability provided by alloy steel with Rockwell C45 hardness, resisting wear and deformation under load.
- Easy installation and removal with the 1/8" hex drive, allowing efficient assembly in confined spaces without a protruding head.
- Reliable fine thread engagement from the 1/4"-28 UNF right-hand thread, offering improved adjustment accuracy and load distribution.
- Broad regulatory compliance meeting ASME B18.3, RoHS 3, and REACH standards for safe, globally accepted use.
Professional Applications & Engineering Value
This black-oxide alloy steel set screw is engineered to address critical challenges in machinery assembly, automotive components, and precision equipment. The fine UNF threads and Class 3A fit deliver exceptional clamping force, reducing the risk of loosening under vibration—a common issue in dynamic systems. The 90° cone point concentrates pressure for a firm grip on shafts, collars, and gears, preventing rotational slip. Made from hardened alloy steel, it withstands high-stress environments without stripping or shearing. Ideal for industrial set screw applications where space constraints and reliability are paramount, this fastener ensures long-term performance while adhering to RoHS and REACH environmental mandates.
Specification Summary & Compliance
This set screw features a 1/4"-28 UNF fine thread with Class 3A precision tolerance for accurate, secure fits. It complies with ASME B18.3 manufacturing specifications and is certified RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, ensuring it meets stringent safety and environmental standards for industrial use.
