- Precise and secure fit ensured by UNC Class 3A threads, providing superior thread engagement and vibration resistance.
- Easy and secure installation with a standard hex socket (7/64" drive) head, allowing for high torque application and a flush finish.
- Guaranteed reliability and interchangeability by conforming to the stringent dimensional specifications of ASME B18.3.
- Safe for regulated industries with full compliance to RoHS 3 and REACH environmental directives.
Professional Applications & Engineering Value
This 18-8 Stainless Steel Socket Head Cap Screw is engineered to solve critical challenges in high-vacuum and precision industrial applications. The vented feature is crucial for preventing trapped air from compromising vacuum levels, making it indispensable in semiconductor manufacturing, analytical instrumentation, and aerospace systems. Its UNC Class 3A thread fit provides a tighter tolerance than standard fits, significantly reducing the risk of loosening under vibration and ensuring a leak-proof seal. The combination of high tensile strength and corrosion resistance offers a durable, maintenance-free solution for assemblies that demand both structural integrity and material purity, maximizing equipment uptime and performance in the most demanding environments.
Specification Summary & Compliance
This screw features a 6-32 UNC thread with a precision Class 3A fit, a length of 1/2", and a standard hex socket drive (7/64"). Manufacturing and dimensional conformance are guaranteed per ASME B18.3. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets the latest environmental and safety standards for industrial use.
