The Yost Vises 104 4" machinist vise with stationary base has an extra-large jaw opening and throat depth, mounts to a workbench to provide clamping action for heavy-duty applications, Federal Specification GGG-V-410B Type VI Class 1, and is made in USA. The stationary base has been machined flat to create a firm foundation for the vise when mounted. The ductile iron body is durable and strong for extended life. The hardened-steel jaws have grooves for enhanced grip and can be replaced when worn. The jaws draw closer together or farther apart by turning the vise handle clockwise or counterclockwise.
The main screw that controls the jaws has been continuous rolled for high strength. A rubber washer on either side of the handle prevents unwanted sliding when turning, and the balls on each end unscrew to enable replacement of the handle if worn. The base has two 33/64"-diameter holes for mounting hardware (not included).

Vises use the clamping action of jaws to hold a workpiece in place for applications such as drilling and sawing. Vise styles are categorized by how the device is mounted. For example, bench vises mount to a benchtop; drill press vises bolt to a drill press; and woodworking vises fit underneath, on top, or to the side of a workbench. A vise's jaw opening and throat depth should be large enough for the workpiece.
Yost Vises manufactures a wide range of vises, including bench-mount, woodworking, and drill-press styles. The company, founded in 1908, is headquartered in Holland, MI.
