I'm looking for a manufacturer who can custom produce a specific thumbscrew made from stainless steel. The current supplier in China is unable to add a nylon threadlock patch to part of the thread, which is essential for my application. Can your team accommodate this request? I can share a PDF CAD drawing to show the exact specifications and location for the threadlocking patch needed. Appreciate your assistance!
