Tighten until you have tension, then strike the end of the screw with a hammer, a 2 lb sledge works well. Then strike the "striker" around, which you'll note is shaped for exactly this operation, placing more tension on. Then strike the head of the screw again. This tool is designed for use exactly this way. I had a J.C. Whitney version break apart on me many years ago, just as others have described. Fortunately I've never had any problem with the two Snap On versions I have, during many uses. -- Bill Parker, South Central Indiana '62 Plymouth Max Wedge; '64 Dart Convertible (Kathi's car); '65 Imperial; '65 Barracuda \6 (Kathi's other car); '68 Hemi Roadrunner; '68 Barracuda Fastback 340-S; '69 Barracuda Fastback now 360 (20 y.o. son's car); '72 Cuda 340 Bill and Kathi, South Central Indiana
