## 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: It works! - Exactly as described. Well finished. It works!
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.

### ⭐⭐⭐⭐⭐ Heavy-Duty Clamp That Gets the Job Done
*by R***S on October 16, 2025*

The BESSEY CM60 C-Clamp is built like a tank. I’ve been using it for woodworking and farm projects, and it holds strong without slipping or bending. The drop-forged frame feels solid and can take a lot of torque without twisting, and the screw mechanism threads smoothly even under heavy pressure. The 6-inch opening gives plenty of range for most clamping needs, and the black finish helps resist rust when used outdoors. I’ve used cheaper clamps before that flex or seize up — this one doesn’t. It’s a simple, no-nonsense tool that performs exactly as it should. If you want a reliable clamp that’ll last for years of shop or farm use, this is the one to get. Excellent quality for the price.
