SELTERM 4/0 AWG (95 mm²) - 1/4" (M6) ⌀ Hole UL Heavy Duty Wire Lugs, Battery Cable Ends, Bare Copper Eyelets, Tubular Ring Terminal Connectors [B115] - 2 Pack

BIG. I bought these to put on the ground lead of my welders. Have not yet had to resort to their use but clearly it will get the job done by using a big hammer to close it upon the lead. So for my purpose if/when the lead brakes I'll have to throw it away. I might try to solder the lead. It's sturdy enough to take heat from my propane torch. If that works, I can use it again should the lead break. I'm pleased with the purchase and hoping the package of 2 will last a long time.The disadvantage of soldering is it nagatively impacts lead. (Speaks to the sorry quality of many ground leads)
