Key Features & Benefits at a Glance
- Enhanced corrosion resistance with black-oxide coating, extending service life in demanding industrial environments.
- Superior holding power provided by the 90° cone point, ensuring a secure, non-slip grip on shafts and components.
- High-strength durability from Rockwell C45 hardened alloy steel, resisting wear and deformation under heavy loads.
- Precise and reliable fastening with Class 3A thread fit, offering tighter tolerances for vibration-resistant assemblies.
- Easy installation and removal using the 1/8" hex drive, allowing efficient maintenance with standard tools.
- Wide compatibility due to UNC coarse threads, facilitating quick engagement in various industrial applications.
- Headless design for flush mounting in confined spaces, enabling sleek and unobtrusive component integration.
Professional Applications & Engineering Value
This black-oxide alloy steel set screw is engineered to address common industrial challenges like component slippage and corrosion. The 90° cone point bites firmly into surfaces, preventing rotational movement in pulley, gear, and collar assemblies, even under high torque or vibration. Made from hardened alloy steel with a Rockwell C45 rating, it withstands repetitive stress without stripping, while the black-oxide surface treatment adds a protective layer against rust and abrasion. The UNC coarse thread and Class 3A fit ensure quick, accurate installation with minimal play, reducing assembly time and enhancing reliability in machinery, automotive, and aerospace applications. Its headless, hex drive design allows for compact installations where space is limited, making it a versatile solution for precision engineering projects.
Specification Summary & Compliance
This set screw adheres to ASME B18.3 specifications, ensuring dimensional accuracy and performance consistency. It features UNC coarse threads with a Class 3A fit for precise tolerance, and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, confirming it is free from hazardous substances and suitable for global industrial use.
