Key Features & Benefits at a Glance
- Vibration-resistant performance with permanent Nylon Patch thread locker, maintaining secure fastening from -70° to 250°F in demanding environments.
- Exceptional durability and corrosion resistance due to Black-Oxide finish on Alloy Steel, extending service life in industrial applications.
- High tensile strength of 170,000 psi and Rockwell C37 hardness for reliable load-bearing capacity and resistance to deformation.
- Precise Class 3A thread fit ensures tight tolerances and smooth assembly with UNC coarse threads, reducing the risk of cross-threading.
- Secure hex drive engagement with a 7/64" drive size and standard socket head profile, allowing for easy installation with common tools.
- Partially threaded design provides optimal grip and clamping force where needed, enhancing joint stability.
- Compliance with industry standards including ASME B18.3, RoHS 3, and REACH, ensuring safety and regulatory adherence for global use.
Professional Applications & Engineering Value
This Socket Head Cap Screw is engineered to address critical challenges in industrial settings, such as vibration-induced loosening and material fatigue. The Nylon Patch thread locker embedded in the UNC coarse threads creates a permanent locking mechanism, ideal for machinery, automotive assemblies, and electronic enclosures exposed to dynamic stresses. Made from Black-Oxide Alloy Steel, it offers superior strength and minimal oxidation, reducing maintenance needs in harsh conditions. The Class 3A thread fit and partially threaded rod design ensure precise alignment and reliable clamping, making it a go-to solution for high-stakes applications where fastener failure is not an option.
Specification Summary & Compliance
This screw features a 6-32 thread size with UNC coarse threads and Class 3A fit for high precision. It meets ASME B18.3 specifications and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and adherence to global standards.
