Key Features & Benefits at a Glance
- Exceptional holding power with Class 3A thread fit for secure, vibration-resistant fastening in demanding applications.
- Superior corrosion resistance from the black-oxide finish, extending service life in harsh industrial environments.
- High-strength durability thanks to alloy steel construction and Rockwell C45 hardness, resisting wear and deformation.
- Secure and efficient installation with the 3/16" hex drive, allowing for high torque application without slippage.
- Reliable positioning with the cup point tip that digs into surfaces, preventing component movement.
- Broad compatibility with UNC coarse threads and right-hand direction, suitable for standard industrial assemblies.
- Regulatory peace of mind by meeting ASME B18.3, RoHS 3, and REACH standards for quality and environmental compliance.
Professional Applications & Engineering Value
This 3/8"-16 UNC set screw is engineered to address critical challenges in machinery and equipment assembly, where loosening under vibration or heavy loads can lead to failures. The black-oxide alloy steel construction provides a robust barrier against rust and corrosion, ideal for outdoor or humid settings. With a Class 3A thread fit and coarse thread spacing, it ensures tight tolerances and quick installation in components like shafts, pulleys, and gears. The hex drive and headless design allow for flush mounting in confined spaces, while the cup point offers superior grip on contact surfaces. These features make it a reliable choice for automotive, manufacturing, and heavy machinery applications, reducing maintenance needs and enhancing operational safety.
Specification Summary & Compliance
This set screw adheres to precise dimensional standards, including Class 3A thread fit for high accuracy in Unified National Coarse (UNC) 3/8"-16 threads. It is manufactured in compliance with ASME B18.3 specifications, ensuring consistent quality and performance. Additionally, the product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances and suitable for global industrial use.
