The Starrett 160 Toolmakers' Steel Clamp, sold by the pair, is used for layout work and for securing work in drilling, welding, and other operations, and has a screw mechanism for adjusting to a capacity of 2" (50mm). Each clamp comes with two take-up blocks that slip on the end of the screw, allowing a slight swivel that angles the block to conform to the work being held. A hole in the base enables fastening to a bench so the clamp can function as a small vise. Each clamp is made of case-hardened steel for strength and durability, and has a smooth finish. Toolmakers' clamps are commonly used in milling, machining, and other metal working applications.

The L.S. Starrett Company manufactures precision measuring tools, metrology and testing equipment, and saw blade products. The company, founded in 1880, is headquartered in Athol, MA.
