- Secure, non-slip installation with hex drive and headless design, allowing flush mounting in tight spaces
- Optimized grip and alignment through cup tip design, preventing component slippage during operation
- Quick, efficient assembly with coarse UNC threads, reducing installation time in production lines
- Broad compatibility with standard 1/4"-20 components, simplifying inventory and replacement
Professional Applications & Engineering Value
This 1/4-20 UNC Class 3A set screw is engineered to address critical fastening challenges in industrial machinery, automotive assemblies, and precision equipment. The 18-8 stainless steel material provides excellent resistance to rust and chemical exposure, while the Rockwell B80 hardness ensures the screw maintains its integrity under repetitive loads and vibrations. The headless hex design allows for seamless integration where protruding fasteners are impractical, and the cup tip creates a firm bite into shafts and collars, preventing rotational movement. With coarse thread spacing, it offers quicker installation and higher resistance to loosening in high-vibration environments, making it a reliable choice for permanent or semi-permanent applications in manufacturing and maintenance.
Specification Summary & Compliance
This set screw features a 1/4"-20 UNC coarse thread with Class 3A fit for tight tolerances and superior thread engagement. It complies with ASME B18.3 specifications for dimensional accuracy and performance. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring it meets stringent environmental and safety regulations for industrial use.
