Cincinnati C-Clamp w/Wing Screw Heavy Duty 4 inch

This is a good, used, clean, pair of heavy duty 4" capacity C-Clamp, marked "CINCINNATI TOOL CO.  STANDARD CLAMP NO. 540 4IN".  As you can see in the pictures the clamp is in good shape, no rust or pitting, very clean, not bent up. There is a few small dings and grind marks. Clame is in very good working order, straight, not bent up, no rust, weighs 1.7 pounds, and has an 7" long frame and the thickness at the clamp pad is 1" diameter, and the threaded screw is 5/8" diameter. This particular type of wing shaped threaded screw end was the earlier style for Cincinnati Tool Co.. Because of the thread design, an amazing amount of pressure can be applied with this type, even though it appears to be a lesser area to get a hold of than the newer style clamps. These were very well made, and are still among the best ever made in this size. A very well made antique clamp, by a well known tool maker! We do combine shipping to save you money, on 2 or more items purchased at the same time!
