## Customer Reviews

### ⭐⭐⭐⭐⭐ Solid!
*by S***G on July 19, 2025*

Very solid construction with thick metal. As others have noticed you need something heavy duty to make the connection. I don't have that but was able to get good results with a hammer and a punch on a concrete surface and the heat shrink hid the sins.ID of the mounting hole is 10.2mm. ID of the connection is 8mm which is more than enough for the 4Ga wire I bought this form. Thickness of the crimp side is about 1.4mm and the lug itself is a beefy 2.8mm.

### ⭐⭐⭐⭐⭐ Solid quality connectors
*by D***D on March 10, 2025*

Worked great when making my own cables!

### ⭐⭐⭐⭐⭐ Heavy Duty, Great Quality, Car Audio A+
*by E***. on July 22, 2024*

These are some of the best Copper Lugs I have used and have become my go to. I have tried many different brands and these are the best.These will require a Heavy Duty Crimping Tool. I bought the blue and black crimping tool from Amazon and it’s a Beast, it takes a huge amount of force to crimp these. The tool I am referring to looks similar to bolt cutters (check pictures if I can include it) Highly Recommend that as well.. Other brands have very little wire inputs that concern me a wire may break loose and touch an amplifier causing damage etc. These have a 1/2”+ wire input sleeve for excellent crimping W/ enough room for a double crimp. Car Audio sites charge $30+ for 8-10 copper lugs that are smaller than these. Other brands may cost lesss but they also have much less material, so consider that when buying. Check my one photo with the TItan 8 Battery and look at the size difference between these copper lugs and another brand sold on here- Night and Day difference. These are perfect for Car Audio - Battery Banks, Capacitor Banks, and Big 3 Upgrades. Highly Recommend!
