I didn't open the it
I didn't open the item immediately upon rpcieet. I tried to use the dial indicator about 2 months after I received it. The threads on the carbide tips were poorly made and would not fit the dial indicator. I contacted AnytimeTools through Amazon.com and after 3 days did not get a response. I then contacted Anytime through the customer service e-mail address and the ultimately received another set of tips which has proper threads. I used the item to measure the runout on a set of automobile disc brake rotors. The runout limit was 0.002 inches which the rotors exceeded. The dial indicator is accurate enough for this type of job. http://njidiggc.com [url=http://nwupmv.com]nwupmv[/url] [link=http://mvboeyil.com]mvboeyil[/link]
