Needed a cheap 4 gauge splitter at the battery terminal, and this was the cheapest one out there at the time. It works just as its intended, but as Im sure many have noticed the set screws are very much on the CHEAP side. Cant for the life of me figure out why someone thought It'd be a good idea to use Phillips head set screws over allen head set screws. I assume they were trying to keep costs down, and they def achieved their goal.
Best advice is to use a screw driver that fits as snug as possible and place it on something solid so you can put your weight into it while tightening to avoid rounding the head.
You can always measure the thread pitch and such then buy some good set screws with an allen or torx head from McMaster Carr or someplace like that. But if youre going to go thru all that trouble, you might as well just save a few more pennies and buy a better splitter.
Would I recommend this to anyone? Probably not, unless youre on a serious budget and this is all you could afford. Does it work? YES it does, but be careful not to round the set screw heads. I don't know if anyone's ever had a power or ground cable break loose and arc under your hood, tho I assure you its not something you want to deal with. Save your cash...buy a better one...or upgrade the set screws.
