Stainless Steel Non-Standard Double-Ended Screws
Non-standard double-headed screws are an extremely flexible engineering connection element. They refer to fasteners with threads on both ends and a polished rod or special-shaped rod in the middle. However, they do not follow national standard sizes or shapes and need to be specially designed according to specific equipment structures, space restrictions or force requirements. This highly customizable nature makes it the first choice when custom-made screws with special shapes are required.
