Dillon manufactures a line of standard and custom stepped hard jaws with a diamond serration pattern for improved gripping of the workpiece. Typically used for first operation work, these jaws feature a gripping surface that accurately contacts most of the workpiece length and diameter for maximum drive. Diamond shaped serrations increase the holding power, especially for rough, irregular and out-of-round components, reducing part slippage and pushback. All standard (catalog) hard jaws are produced using 8620 steel to provide a tougher core, then carbonized and hardened to Rc 52-55 for more durability and corrosion resistance. Dillon special top jaws are ideal for rough cast, forged, irregularly shaped, thin walled or extra-long workpieces that require special attention and handling. 

Custom top jaws, manufactured to customer specification, center the workpiece and grip it equally. Extra wide jaws are available for a wider gripping surface. Dillon engineers work with customers to supply jaws that meet particular design and production requirements. Approval prints are supplied for each custom jaw order, and certification of materials and process, and heat treating are available upon request. 

All of the company’s hard stepped jaws are available in various mounting configurations, including serrated, T&G, Acme and square serrated key types to fit all brands of chucks. With multiple radii for both inside and outside clamping, they are ideal for any size run.
