In summary, to attach a clamp to a metal bar, first ensure the bar is clean and free of debris. Open the clamp and position it around the bar at the desired location. Tighten the clamp's screw or lever mechanism securely while ensuring it is aligned properly. Check for stability and firmness before use.

TL;DR Summary
clamp attachment to metal bar
Hi, I am trying to find a way to attach the clamp to the metal bar seen in the picture so that they become a rigid unit. I am not sure what is best way to do it. Drilling somehow? screws where? if anyone has a suggestion, please let me know. The metal bar in black seen in the picture is hollow...
thank you
TP

Welcome, @tirelessphoenix ! :cool:

What is the meaning of the third picture?
How much wider is the bar than the jaw of the clip?
How long is the bar?
What do plan to use that tool for?

the meaning of the third picture is just to show that I want the clamp and the bar to become a fixed 'unit'.

I want to use it to attach things

the bar is 1 inch long

Assuming the metal bar is actually a square hollow tube.

Make a square section tapered, wood or plastic block. Hammer the wedge into the end of the tube, with glue in the gap.
Drill the clip with 2, 3 or 4 holes where it will contact the end of the tube. Mark that hole pattern on the end block, then drill undersize.
Attach clip to block with screws that slightly expand the internal wedge, locking it in place.

If welding is out of the question, you could make a metal block that will fit within the square tube. Two holes drilled in the lower side of the clamp and two larger access holes in the upper part of the clamp. Use two rounded head screws to hold the clamp to the block and other screws or bolts & nuts to hold the block within the tube through holes you previously drilled.

What tools and materials do you have available?

I actually came up with what Jack action just described. I have drill press, but not that powerful. But I think enough to drill through the metal bar. I didn't think about the welding option...mmm... Im a complete noob about welding...I think I'll try first the drilling. Glue cannot be used.... thank you a lot guys!

Why not?

Does this need to carry significant current and/or load ?? (*)
If not, and tube is a 'standard' size / shape as used for office etc furniture, consider a press-in plug with threaded insert for M6~M8~M10 adjustable foot.

Such may be handy for rapidly positioning / re-positioning other end of pipe, too.

Hole on both jaws, upper hole allows easy torqueing of matching CSK or pan-head machine-screw through lower. If you need low-current / anti-static continuity, a strand of eg 3-Amp wire from under screw-head to between plug and tube should suffice, provided any coating is scraped away...

*) Gotta ask, as welding connections are in a different league...

Welding of those thin galvanized pieces would be very difficult for any unexperienced person.

If available to you, I would recommend one 1/8-inch all-thread bar, one fender washer and two nuts (only one hole to be drilled on the clamp).

If you can grind the shape of the bottom jaw onto the top of the metal bar, any rotation of the clamp would be restrained.
If no grinding capability, two sheet metal screws into the clamp and against opposite corners of the bar could achieve the same effect.

What sort of things? The springs on those clamps are not very strong so what direction will the force be required to work in? is the tension in the direction of the clip or at right angles?

Going back a bit, do you really need to use a simple cable clip. There are many other fixings available for a host of applications. Take a look in catalogues of fixings to make sure you are heading in the right direction.

FAQ: How to attach clamp to metal bar?

1. What type of clamp should I use for a metal bar?

The type of clamp you should use depends on the size and thickness of the metal bar, as well as the intended application. Common options include C-clamps, bar clamps, and pipe clamps. Ensure that the clamp's jaw capacity exceeds the thickness of the metal bar for a secure fit.

2. How do I ensure a secure grip when attaching a clamp to a metal bar?

To ensure a secure grip, clean the surface of the metal bar to remove any dirt, grease, or rust. Position the clamp jaws evenly around the bar and tighten the clamp gradually, checking for a firm hold without over-tightening, which can damage the bar or the clamp.

3. Can I use a regular clamp on a metal bar?

While you can use a regular clamp on a metal bar, it is advisable to use clamps specifically designed for metal to ensure better grip and durability. Regular clamps may not provide sufficient pressure or may slip off due to the smooth surface of metal.

4. What precautions should I take when using clamps on metal bars?

When using clamps on metal bars, wear appropriate safety gear such as gloves and goggles to protect against sharp edges. Make sure the area is clear of obstructions, and avoid over-tightening the clamp to prevent damage to both the clamp and the metal bar.

5. How can I prevent damage to the metal bar when using clamps?

To prevent damage to the metal bar, consider using protective pads or rubber inserts on the clamp jaws. These materials can distribute the clamping force more evenly and reduce the risk of scratches or dents on the metal surface.
