TKDMR10pcs 4 Awg-3/8" Ring Marine Grade Copper Wire Lugs,with 3:1 Heat Shrink Tubing,UL Battery Cable Ends,Heavy Duty Cable Lugs,Tinned Copper Eyelets,Tubular Ring Terminals

Excellent build. I like the bevels around the entry hole to better funnel stray wires into place. Nice heat shrink. Heck, even nice packaging.

Good quality

While I can speak for longevity of these connections, the factory wiring in my boat wasn't even tinned and it lasted 25 years with zero issues. I used these to make runs from my house battery to my ground and hot busses to run two separate speaker amplifiers off of.You will definitely want a hydraulic crimper for these things. They are STIFF. Way more crimping force was required for these than the Ancor connectors we used in the past. But at 10$ for 10 of these and $10 for two Ancor connectors, I would rather take my chances with these.Our stereo plays loud and clear and we haven't had any connectivity issues so far.

Very happy with the quality, fit, and finish on these lugs. Will be purchasing again for my next project.

Very nice ring lug and good quality shrink sleeve. Makes a good quality connection, if the correct crimp tool is used.

Well-made crimp style lugs for battery connections. The included heat shrink tubing is a nice extra.

Good quality. Easy to crimp and the shrink tubing works well.

Very sturdy and material is cut to perfect length. I used these to rewire a golf cart.
