Du-Bro 504 Threaded Stud Driver

This unique tool takes the hassle out of threaded studs and threading threaded rods into plastic push rods (such as DU-BRO Lazer Rods and other push rods on the market). To use, simply thread your stud or rod into either the 4-40 or 2-56 end of the driver until it bottoms out. Then thread rod/stud into plastic push rod until desired length is reached and finally back off driver. It s fast and easy! No more damaging threads with pliers. Made in USA
