This is the Sherline Step Block Hold-Down Set. This style clamp set has long been popular on full-size milling machines, and manufacturer now produces a nice set suitable for miniature machine tools. The step blocks are notched as the back of the clamps to make it quick and easy to set your clamps to the proper height. A selection of threaded studs from 1″ to 3-1/2″ is provided to allow a variety of heights to be selected quickly. The nut and washer design is a nice touch too. The bottom of the nut is convex while the top of the washer has a matching concave surface. Even if the clamp isn’t level, the washer will seat flat on top of it while applying even pressure. Also provided is a spare, unanodized step block that you can cut down to make smaller size step blocks for low setups. At least one set of hold-down clamps should be considered a necessity for every milling machine owner.

The maximum height of part that can be clamped with the screws provided is about 3″ (76 mm).
