- High mechanical strength with 70,000 psi tensile strength and Rockwell B70 hardness for reliable performance under heavy loads
- Secure fastening and easy installation thanks to the external hex drive and coarse UNC thread design
- Precise thread engagement with Class 2A thread fit ensuring consistent, vibration-resistant connections
- Optimized for partial-thread applications where unthreaded shank provides enhanced shear resistance
- Compliance with industry standards including ASME B18.2.1 for dimensional accuracy and reliability
- Environmentally responsible manufacturing with full RoHS 3 and REACH compliance
Professional Applications & Engineering Value
This 1/4"-20 UNC hex head screw in 316 Stainless Steel delivers critical performance in demanding industrial settings where corrosion and mechanical stress are major concerns. The partially threaded design provides a non-threaded shank section that resists shear forces, making it ideal for machinery, structural assemblies, and marine equipment. The coarse thread ensures quick installation and superior grip in softer materials or where vibration loosening is a risk. With its external hex drive, it allows for high-torque application using standard tools, reducing assembly time while maintaining joint integrity. These features make it a preferred choice for chemical processing, offshore, and food-grade applications requiring durability and regulatory compliance.
Specification Summary & Compliance
This screw features a 1/4"-20 UNC coarse thread with Class 2A thread fit for standard tolerance and interchangeability. It is manufactured to meet ASME B18.2.1 specifications, ensuring dimensional consistency. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, confirming adherence to environmental and safety regulations.
