## Description

Product Description The BESSEY CM series light duty, drop forged c-clamps are economical, yet sturdy. These clamps are strong enough for light duty welding & fabrication work, while being light enough to use in model construction & various other crafts. Great for many jobs around the home & in the home workshop. BESSEY. Simply better. From the Manufacturer Ductile Iron Frame and Hardened Steel Spindles w/ Swivel Pads. 4" Capacity x 3" Throat Depth.

Review: Good quality for a medium duty budget priced clamp - I purchased a few of these for a project needing a moderate amout of clamping force with a 3" throat. While advertized in some places with having a 3-1/2" throat, the throat depth only measures at 3-1/4". Most budget priced C clamps are made of cast or malliable iron, which will break if over loaded. These Bessy C clamps are advertised as being made of forged steel, which is much stronger. The screw is, as expected in this proce range, to be smaller in diameter than the heavy duty Armstrong C clamps I have, but is more than adequate. It has an Acme thread which is stronger than a regular angled screw thread. LOL, I was so pleased after using them that I would have bought a few more, but after the New Year the price went up, so I think I'll get by with the ones I have for now.
Review: The Best For Clamping - These metal clamps are so much better than the plastic jaw ones. Hubs and I were assembling a plant bench and needed some clamps to hold slats together while the wood glue dried and these worked perfectly. Both of the plastic clamps broke off. These are very durable and should last for years.

### ⭐⭐⭐⭐⭐ True C clamp
*by D***N on November 14, 2025*

Very well made C clamp. I had one for over 30 years and lent it out or misplaced it. But it was made differently. It was square top and bottom. Not a true C clamp. This gives me a recess top and bottom for clearance. I had many times needed a true C clamp and had to use spacers to get clearance. Love the quality and value.
