Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 Stainless Steel construction, ideal for harsh environments and extended service life
- Exceptional holding power ensured by the Class 3A thread fit, providing a tighter, more secure fastening with minimal backlash
- High mechanical strength and durability from Rockwell B80 hardness, resisting deformation under load
- Secure, flush installation with the headless and cup point design, preventing component interference and improving grip
- Efficient installation and removal using the 1/8" hex drive, allowing for high torque application in confined spaces
- Reliable coarse UNC threading for quicker assembly and reduced cross-threading risk in industrial applications
- Full regulatory compliance with ASME B18.3, RoHS 3, and REACH, ensuring safety and environmental standards are met
Professional Applications & Engineering Value
This 316 Stainless Steel set screw is engineered to address critical challenges in demanding industrial settings. Its corrosion-resistant properties make it perfect for applications exposed to moisture, chemicals, or outdoor elements, such as marine equipment, chemical processing machinery, and food-grade systems. The cup point design bites securely into shafts and collars, providing excellent resistance to loosening from vibration—a common issue in motors, pulleys, and precision assemblies. Combined with the UNC coarse thread and Class 3A fit, it ensures rapid, reliable installation and long-term performance, reducing maintenance needs and downtime. The hex headless style allows for a clean, unobtrusive finish, ideal where space is limited and a smooth surface is required.
Specification Summary & Compliance
This set screw features a 1/4"-20 UNC thread with Class 3A precision fit and coarse thread spacing, ensuring dimensional accuracy and reliable engagement. It is manufactured in compliance with ASME B18.3 specifications and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming its suitability for global industrial use without hazardous substances.
