Copper Ground Rod Clamp, Great for 1/2”- 5/8’’ Grounding Rods (2, CP58 (1/2''-5/8''))

They work

Nice item. Well built.

Using on #8 wire to to 8 ft grounding Rod.

Use these to attach ground wire from coax wall feed through to my ground rod.

I have been buying and using ground rod clamps for decades. I don't feel like I over tighten this clamp and certainly didn't tighten more than the one I was replacing. Before I was at a point I thought it was tight enough, it snapped. Metal is thin and looks porous. The seller reached out to me and offered a full refund even though two were in a pack and one broke. I accepted half refund.

I use these because they're more durable than another style of ground clamp I had purchased and used. The other clamps were two piece and prone to cracking and breaking, even when hand tightening. Easy to install, functional and good value.

Nice over the top quality

I used these to clamp a #8 wire to a ground rod. As I was tightening it, it cracked. I wasn't over-tightening it. They are some sort of cheap pot metal that is coated with a copper finish - they are not solid copper or brass. They are a complete rip-off. Don't buy them.
