Head: The head of a socket bolt is typically cylindrical in shape and has a recessed hexagonal socket. The socket allows for easy insertion and removal using an Allen wrench or hex key. The socket head provides a low-profile appearance when installed, making it suitable for applications where a flush surface is desired. Shank: The shank refers to the straight, cylindrical portion of the bolt between the head and the threaded portion. It is typically unthreaded or partially threaded, depending on the specific application requirements. Threads: The threaded portion of a socket bolt extends from the end of the shank to the tip. The threads are designed to engage with a corresponding threaded hole in a nut or a pre-tapped hole in the material being fastened. Socket bolts commonly feature metric threads, and they can be found in various thread sizes and pitches. Material and Strength: Socket bolts are typically made from steel or stainless steel, but they can also be found in other materials such as brass or alloy steel. The strength of a socket bolt is determined by its grade or class, which is often indicated by a numerical marking. Common grades include 8.8, 10.9, and 12.9, with higher numbers denoting greater strength.
