  • Very good value and function well.
These are so much easier then the type that need a nut driver or screw driver. I am using them to hold together a 3D printed vent system. It doesn't require a lot of holding force but I've messed around with these and think they would be absolutely excellent on my electric clothes driver vent. The work very well, easy to tighten and loosen as needed. Highly recommend. ... show more

  • Good Clamp
These are a lot easer to use than the one's without the thumb screw unless you are using a frill with a 1/4 bit to clamp it down. If you want something easy get some of the spring clips that you squeeze and you will never use anything ela=se

  • Easy
Kind of chintzy feeling, but did the job and held ductwork together as expected.

  • Ok for the money
They are decent. The knobs come off very easily though

  • Thumb Screw Works great
Using in my shop for my new air filtration system, seal the saw dust in the system of bags. Just what I needed and fit the four inch hose connections.

  • look good, and clamp well
Generally a good product. If the clamp needs tightened a lot, yet still within the supposed operating range, the tail protrudes from the lead screw and collides with the thumb screw and becomes more difficult to tighten. Not terrible, just annoying. Once tightened everything is fine.
