Professional Applications & Engineering Value
These 5-40 UNC socket head cap screws are engineered to solve critical fastening challenges in industrial machinery, automation systems, and precision equipment. The 18-8 stainless steel material provides excellent resistance to rust and oxidation, making these hex drive screws suitable for applications exposed to moisture, chemicals, or outdoor elements. The partially threaded design offers a non-threaded shank for precise clamping, while the coarse thread configuration ensures rapid assembly and superior performance in high-vibration environments. With their high tensile strength and Class 3A thread fit, they deliver reliable, repeatable fastening in critical joints, reducing maintenance needs and downtime in industrial fastening applications.
Specification Summary & Compliance
This product features a Class 3A thread fit for high precision, manufactured to UNC coarse thread standards with a 5-40 thread size. It complies with the ASME B18.3 dimensional specification and is supplied in the inch system. The screws are RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring they meet stringent environmental and safety regulations for industrial use.
