Upgrade Baudelun 1/4"-20 Beam Clamps, Black Steel Bolt-on Beam Clamp for 1/4" and 3/8" Threaded Rod, S-hooks and Bridle Rings, 25 Packs

Good quality and easy to install

These were good. Fit right. Didn't bend when. Tightening and the side bolts hel boxes and conduit good.

Build quality:Calling these clamps garbage would being doing garbage a disservice. Horribly made Chinese metal failing at the simplest of clamping tasks. The clamps would bend, pop, or crush - even the f'n tightening screws would bend. Avoid these clamps - save yourself a huge headache, and spend a pit more money on something stronger/better,

Certainly, you can use these to place a clamp on the web of a W or I girder and then attach a conduit clip with a 1/4-20 bolt or you could pass through the end holes a piece of 3/8 threaded rod and put some jamnuts on it to suspend a light fixture or something. However, these are great for grabbing onto metal materal that has a seam or folded edge. Need to put dividers on a metal rack shelf in your garage, these clamps solidly attach and make connections easy, but no holes to drill. Yes, they clamp and will leave a mark on the metal surface, but that is easy to refinish than weld points or holes. Also, if you need to clamp a few pieces of strap metal before welding, these are great temporary holders for that and allow for multiple attachment points. I always keep a few in my tool box for "just in case."

When tightening the clamp, it flexed and bent outward at sides. Metal is thin and has flaps that fold over to maintain rigidity. Will not buy again….

I used to use a cast iron version of these clamps to hang fire protection sprinkler piping in warehouses, malls and other types of new construction where fire protection systems are required by law.These are very similar but are made of folded sheet metal for small diameter pipe or conduit and they can be clamped to beams or other structure up to 3/4" thick. They are threaded for both 1/4" and 3/8" All Thread Rod or can be used to hang hooks to hang tools or other items on to organize a garage or shop area.These are a great deal for only $20 which is less than $1/ clamp and they work as expected so they get 5 stars from me!

These clamps are light metal and for small diameter pipe or conduit. They also work on flat surfaces up to 0.75” (3/4”) can be clamped to beams with additional hardware to route electrical wires or other light-duty tasks. I would not use them in high stress area as they will bend with moderate force. They are coarse-threaded (#10-20) for both 0.25” (1/4") and 0.375” (3/8") so threaded rod, eye hooks, and bolts will fit into the clamp. Note I would recommend a lock nut against the clamp as the threads are minimal and will loosen with any movement. My application was to test these was as safety clamps to stabilize a tall stack of air filters on a dust collection system. They worked well installed against the stack and they also allowed a steel cable to be connect between two of the clamps for extra safety. I would like to rate them 5-stars as they are very useful however, they lose a star for construction and strength. Still a good purchase for what they are designed to do.

This is a set of 25 beam clamps. They are made of premium black powder coated steel that will stand up to corrosion and a long service life. Each of the clamps have 1/4"-20 and 3/8" threaded holes for mounting of hanging support rods or fasteners. The included threaded bolt gives the clamp a strong and sturdy bite on flanges. The clamp bolt has a phillips head and hex head for use with multiple installation tools.Would recommend these to anyone.
