Ampper Brass Battery Terminal Connectors, Top Post Battery Terminals Clamp Set for Marine Car Boat RV Vehicles (Wing Nuts, 1 Pair)

This is a decent well made battery clamp made of brass. Most are made of lead. What I like is I use these in a marine and other applications. They are very durable and long lasting, and corrosion resistant. The one thing to be careful is over tightening! They are tight enough when both legs that the bolt go through are parallel and you cannot turn the the clamp on the battery post. Going further you can crack or break one of the legs. The brass is a copper & zinc derivative. Lead clamps on the other hand are forgiving but will start too loosen if over tightened. Lead is a good conductor but not as good as brass and not a good steward to the environment.

Worked as advertised.

Nice quality. Although the bolt for the wiring is very large. Had to drill out the holes on my connectors. It's much bigger than standard.

Work great but one broke after I tightened it and walked away. Came back later and it was broken off the post. I may have over tightened though.

Solid, very well built! Thank you

Purchased a few sets of other terminals from online and local auto parts store. They were all very low quality with hardware that stripped and holes that didn’t fit the terminals very well. These were the same price but fit perfectly and have a solid hold on both bolts

When i saw these i knew they were for me. These replaced the original Chrysler battery clamps that a real joke. These were strong and fit tight on the post, These unlike others do not work their way loose.

Just like many others have said, they crack. I purchased a Dozen or so of these and immediately installed 4 of them. After a few months, 3 of them are cracked in half. And no,i didnt over tighten them. Just very poor quaility metal. I'll be tossing the remaining new ones and finding a different brand.
