- High tensile strength of 100,000 psi ensures reliable, secure fastening under significant mechanical stress.
- Coarse UNC thread and Class 2A fit provide easy, quick installation and excellent thread engagement.
- Partially threaded design allows for precise clamping force and prevents over-tightening in assemblies.
- Slotted drive and rounded head offer straightforward installation with standard tools and a smooth, finished appearance.
- Compliance with ASME B18.6.3, RoHS 3, and REACH guarantees adherence to strict industrial and environmental standards.
- Rockwell B100 hardness maintains structural integrity and resists wear over repeated use.
Professional Applications & Engineering Value
This 3/8"-16 UNC rounded head slotted screw is engineered to solve critical fastening challenges in industrial settings. The 18-8 Stainless Steel material, combined with a passivated finish, provides exceptional resistance to rust and chemical exposure, making it ideal for outdoor equipment, marine hardware, and food processing machinery. Its coarse thread and Class 2A thread fit ensure rapid assembly and reliable hold in materials like metal and hard plastics, reducing installation time and minimizing thread stripping. The partially threaded shank design concentrates clamping force where needed, preventing joint failure in high-vibration applications such as automotive assemblies and structural frameworks. By meeting ASME B18.6.3 specifications, these screws deliver consistent performance and interchangeability, supporting efficient maintenance and repair operations in B2B procurement environments.
Specification Summary & Compliance
This screw features precise Class 2A thread fit and UNC coarse threading with a size of 3/8"-16, ensuring dimensional accuracy per industrial standards. It is manufactured in compliance with ASME B18.6.3 for mechanical and dimensional consistency, and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances and suitable for global supply chains.
