Remove studs without damage with the 4-piece Stud Puller Set. During any major restoration project you will encounter studs which need to be removed for repair or replacement. Trouble is how to do it without destroying the studs? This set of four stud pullers are operated by a 1/2 drive ratchet or T-bar and grip the stud on three sides, tightening more the harder you turn, to remove even the tightest of studs. Much easier than risking stripped threads by using locked nuts, etc. Fits 6mm to 12mm studs. See the How Do I Remove Broken Studs? article in the Technical Articles section
