Heimann Transfer Screws Set Lot of 14 Machinist Layout Punch Tools Urbana OH

14-piece user lot of high-quality Heimann mechanical transfer screws (sleeve/punch style), made in Urbana, Ohio. These are indispensable precision layout tools for tool and die makers, manual machinists, fabricators, and gunsmiths to precisely transfer blind threaded hole centerlines onto mating workpieces.

Unlike standard solid transfer screws, the Heimann hex-sleeve design houses an internal pointed punch point, allowing you to use a wrench to back them perfectly flush into a tapped hole.
