A capped bamboo-joint screw includes a screw body with a set of threaded grooves and a set of unthreaded areas on its outer surface. An adapter post is connected to the left side of the screw body, and a nut is connected to the left side of the adapter post. This device utilizes the alternating distribution of threaded grooves and unthreaded areas. When adjusting the screw length, the user can use pipe wrenches or wire cutters to clamp the unthreaded area and precisely cut it off along a preset break point. The threaded grooves remain intact after cutting, not affecting subsequent threaded connections with nuts or installation components, greatly expanding the length adaptability range and reducing the need for stock specifications. Simultaneously, the Phillips head groove on the left side of the nut, in conjunction with the adapter post, ensures that torque is effectively transmitted to the threaded section when tightening the screw with tools, enhancing installation stability. Furthermore, the integrated metal cap design makes this product aesthetically pleasing and provides excellent protection.
