Shoulder Screw

A shoulder screw, also known as a shoulder bolt, is a type of machine screw with integral threads that are only present on half or less of the screw shank . The screw has a partially smooth shaft that allows the bolted material some rotation and movement around the screw axis, while the threaded end typically has a nut to maintain the screw's position.The screw must be used with pre-drilled holes and is common in machinery with vibration and heat variations.The screw has an unthreaded shoulder under the head that is larger in diameter than the threads.The shoulder provides a freely rotating pin joint connection to another part, allowing axial clearance.The screw may be used in conjunction with a plain bearing, such as a nylon bush, to provide improved rotation between the parts.
