The Uxcell stainless steel C-clamp is a small, 304 stainless clamp for light holding jobs in woodworking, metalwork and hobby welding. Per the Amazon listing, it has an M6 x 1 mm screw, an I-beam frame, clamping pads and a 0 to 14 mm clamping range. It is worth considering for thin stock, jigs and stainless projects, but it is far too small for heavy fabrication. The Uxcell stainless steel mini C-clamp is a small 304 steel clamp for light jobs.
Quick specs at a glance
| Item | Detail |
|---|---|
| Product | Uxcell stainless steel C-clamp (small size) |
| Material | 304 stainless steel, per the listing |
| Thread | M6 x 1 mm |
| Clamping range | 0 to 14 mm (about 0.55 in), per the listing |
| Jaw opening | Listed as 0.79 in (20 mm) |
| Frame and size | I-beam frame, roughly 30 x 24 x 26 mm, per the listing |
The listing gives both a 0.79 in opening and a 14 mm clamping range, so verify the usable range against your stock. It also does not make clear whether the weight is for one clamp or a pack.

What it is and who it suits
This is a miniature C-clamp, closer to a jig or model-making clamp than a shop clamp. The small body and M6 thread give modest force, which is fine for holding thin sheet, brackets, glue-ups and small parts.
304 stainless is the draw. It does not rust the way plain steel does, and it will not leave carbon-steel contamination on stainless parts. That makes it handy for stainless fabrication fixtures and wet or outdoor jobs.
If you need clamp force for plate or structural steel, step up to a forged C-clamp.
How to check it fits your project
- Stock thickness: keep your material comfortably inside 14 mm (about 0.55 in), with allowance for pads.
- Clamping force: a small M6 screw is for light holding, not heavy plate.
- Quantity: check whether the listing sells one clamp or a multi-pack.
- Heat: stainless conducts heat more slowly than mild steel, but the clamp still gets hot near the weld.
- Throat depth: a small body limits how far from an edge you can clamp.

Pros and limitations
Pros
- 304 stainless resists rust and cleans up easily.
- Small and light, so it does not drag thin stock.
- Clamping pads help avoid marking surfaces.
- Suitable for stainless work where carbon contamination matters.
Limitations
- Small capacity and clamping force.
- Stainless is softer than hardened tool steel, so don’t over-tighten or use a cheater.
- Spatter can stick to the screw and pads.
- Not a replacement for a ground clamp.
Using small C-clamps in welding
- Clean the contact surfaces and set the pads square to the material.
- Tighten by hand to firm pressure. Do not use pliers or a wrench on the screw.
- Place the clamp away from the weld zone, or cover threads with a spatter shield.
- Allow the work to cool, then loosen and wipe the screw.
Never rely on a clamp this small to hold anything structural or heavy. Use gloves when removing clamps from hot work.

Frequently Asked Questions
What size is the Uxcell C-clamp?
The listing gives a body of about 30 x 24 x 26 mm, an M6 x 1 mm screw and a clamping range of 0 to 14 mm. It is a small clamp. Check the listing for whether you get one clamp or several.
Is 304 stainless good for welding clamps?
It resists rust and does not contaminate stainless parts with carbon, which helps in stainless fabrication. It is not as hard as forged steel, though, so it suits light holding. Spatter can stick to it like any other clamp.
Can I use it as a welding ground clamp?
It is not designed as one. Stainless conducts electricity less well than copper or plated steel clamps made for the purpose, and the small contact could overheat. Use a proper ground clamp rated for your machine.
How tight should I tighten it?
Firm hand pressure is enough. Over-tightening an M6 stainless screw can strip the thread or bend the frame. If the work still moves, use a bigger clamp or a different hold-down method instead of adding leverage.
Final verdict
The Uxcell stainless C-clamp is a neat small clamp for thin stock, jigs and stainless work where rust matters. It lacks the force and reach for heavy fabrication. Check the current listing for quantity and details.
