Square head set screw for American Hoist 9299

This square head set screw, part number 803163, serves as a specialized fastener for the American Hoist 9299 crane. It features a cup point design and is manufactured with a 1/2-13 UNC thread specification and a length of 3 inches. The square head allows for tightening with standard tools, while the cup point is engineered to press against a surface to prevent relative movement between components.

This component is intended for use in the American Hoist 9299 model. It is commonly utilized to secure parts such as gears, pulleys, or collars to shafts within the machine assembly.

Set screws are mechanical fasteners used to lock a rotating component to a shaft. By tightening the screw through a threaded hole in the outer part until the point bears against the shaft, the assembly is prevented from sliding or rotating independently. This type of connection is standard for maintaining the alignment of mechanical power transmission components in heavy machinery.
