Key Features & Benefits at a Glance
- Superior corrosion resistance thanks to 18-8 stainless steel construction, ideal for harsh environments and long-term reliability.
- Excellent torque transmission and anti-slip performance from the square head and external square drive, ensuring secure fastening.
- High mechanical strength and durability with a Rockwell B80 hardness, resisting wear and deformation under load.
- Reliable coarse UNC thread (5/16"-18) for faster installation and reduced cross-threading risk in industrial assemblies.
- Secure locking capability provided by the cup point tip, which digs into surfaces to prevent component movement.
- Precise dimensional fit with Class 2A thread tolerance, ensuring consistent performance and interchangeability.
- Compliance with major industry and environmental standards including ASME B18.6.2, RoHS 3, and REACH for safe, regulated use.
Professional Applications & Engineering Value
This 18-8 stainless steel square head set screw is engineered to address critical challenges in industrial fastening, such as vibration loosening and corrosion-induced failure. The coarse UNC thread (5/16"-18) and cup point tip work in tandem to provide a deep, secure bite into shafts and hubs, effectively preventing slippage in high-torque applications like machinery, automotive components, and power transmission systems. Made from corrosion-resistant 18-8 stainless steel, it withstands exposure to moisture, chemicals, and outdoor elements, reducing maintenance needs and extending service life. The square head design allows for high-torque application with standard tools, making it a reliable choice for assembly lines and heavy-duty equipment where durability and precision are paramount.
Specification Summary & Compliance
This set screw features a 5/16"-18 UNC coarse thread with Class 2A fit for consistent dimensional accuracy and ease of assembly. It is manufactured in compliance with ASME B18.6.2 specifications, ensuring mechanical and dimensional reliability. The product is also RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent environmental and safety regulations for industrial use.
