I am going to use marine terminals over the large posts on my Group 27 starting wet cell marine battery....thus avoiding the use of the built-in threaded post (not a strong connection).
I found these Military terminals and they look really good.... they are low profile (reduce overall heigh by approx. 1/2"-1" which I need) and you can connect your ring terminals on both sides of the bolt. Plus, the protective boots are large and cover nearly the entire post//threaded post.

However, these Military terminals come with both bolts sized 3/8". These are where the ring terminal are connected. The 5/16" is used solely for tightening the clamp terminal to post.
The 3/8" ring terminal on positive starter cable from my motor fit great. I do not want to drill out or ream out my starter negative cable (5/16") to accommodate the 3/8" bolt, as my motor is new and do not want to chance any warranty issues for mods made to cable.
I was considering using a 5/16" bolt in place of the 3/8" bolt, would this work? Both nuts I am using are lock nuts.
The Amazon seller said NO to doing this...Quote, "The 5/16" bolt has too much room for movement and is prone to loosen. Additionally the amount of contact between the bolt and the terminal is greatly decreased which could lead to a buildup of heat in the terminal when drawing high amounts of current." Does this sound correct? It is on the negative side if that makes any difference.
Thanks!
