Socket Shoulder Screws

A socket shoulder screw, also known as a shoulder bolt, is a type of threaded fastener with distinct characteristics: Socket Drive: Similar to socket jam screws, socket shoulder screws have a socket drive head. This design allows for precise torque application, usually with an Allen wrench or hex key, making them easy to install and remove. Shoulder: The defining feature of a socket shoulder screw is the presence of a shoulder, which is an unthreaded cylindrical section of the shaft between the head and the threaded portion. The shoulder serves as a precise spacer, providing a smooth, flat, and accurately positioned surface for other components to rest against. Threaded Section: Below the shoulder, socket shoulder screws have a threaded section that allows them to be securely fastened into a threaded hole or nut. Socket shoulder screws are commonly used in applications where precise spacing, alignment, and load-bearing are crucial. The unthreaded shoulder acts as a bearing surface or spacer, helping to maintain alignment and ensuring that the components remain separated by a specified distance. These screws are often found in machinery, automotive, and assembly processes where tight tolerances and precise positioning are required. They are available in various materials and sizes to suit different applications and specifications.
