6 Inch Inside Calipers, 6-3/4 Jaw Opening

The media could not be loaded. I was impressed with the quality of this outside 6in caliper. The spring has good tension, the adjusting nut is tight enough it doesn’t back off on its own but it also it adjusts smoothly without any resistance. I believe these were listed at about six or seven dollars when I got them, so, I expected they would be a little flimsy but there’s nothing cheap or flimsy about the quality of these calipers! Only thing to note is they are very oily when they come and I would except them to rust if they get wet or are kept in a humid environment unless they are kept well oiled.
