The 1.167.0700.01, also known as part number NM-63-BE, is a locknut designed to securely fasten threaded components while establishing a reliable electrical ground. It is manufactured with an M63 x 1.5 metric thread. The component has a thickness of 0.24 inches (6 mm) and requires a wrenching flat dimension of 2.76 inches (70 mm) for installation. Its primary feature is the integrated cutting edges ('BE' type) which bite into the mounting surface, making it ideal for EMI/RFI sensitive applications where secure grounding is critical.
