Side Mount Battery Terminal Posts

[PAToyota]

Ok, I have a dual (top & side) post battery. I'm hooking the main cables up to the top posts, but want to use the side posts for auxiliary shit.

What I'd like is something like this that screws into the side posts:

But all I can find is 5/16" and I need 3/8-16 to screw into the battery.

I've been searching for awhile and most of what I'm finding is either this - or this:

Does what I want exist? What search terms do I need to use?

It looks like the size listing is for the end that you would hook cables to, rather than the end that he wants to screw into the battery side post. That's why it lists 3/8" and M10

I would probably pick up a set of those in 3/8 and then get some 3/8 threaded brass rod from mcmaster and just make it work. On my brother's CJ we just bought some side post bolts from oreilly's and stacked washers until it would tighten down.

Thanks.

Honestly, all I was getting was 5/16" (and 1/4") results. Nothing 3/8" was coming up.

Well, 3/8" is 9.525mm, so I'm thinking they're saying either size.

Will's result led to this one: https://www.amazon.com/dp/B09N915FKG

Which has this picture, so it looks like either of them would work for what I want.

By the way, now Amazon is giving me all kinds of 3/8" choices that I swear were not there in my searches over the past few days.

Yeah, I have stainless bolts and washers but had something fall and hit the positive bolt and the body and short out, so I was looking for something insulated.

Thanks. I'm tired of stacking washers. This will be much better.

It's called a bolt, then you use a nut to suck it down instead of stacking washers like a smooth brain.

Theres also such things as a plastic hex cap to use as an insulator.

But the post is less ghetto...

It's called a ⅜ x 1" ss set screw...

 

[Grendel]

With a vacuum cap from your collection jammed over it as the insulator.


I prefer using the side post for the starter cables and chucking a set of “military style” terminals on the top post for hooking other stuff to. I think it’s cleaner and I’m unhooking my winch a lot more than my starter cables, so I’m not worried about stripping out the threads in the terminal by being a gorilla.

Be sure the side posts are rated for the draw. Not all are.

Yeah, I'm somewhat surprised GM used side post batteries on their diesels.

Switching the starter to the top lugs has made a noticeable difference.

Been doing that for years.

3/8" bolt with nut. Screw bolt into side terminal, use as stud. Tighten nut down until it's tight. Use flat washer underneath.

Edit: Dammit TRINDU somehow I skipped your post? Beat me to it

That's car stereo territory.

For all the people that keep saying to use a 3/8" bolt...

I picked up a couple of ones Will Scarlet linked. Unfortunately, they seem to be more the M10 than the 3/8" and wouldn't thread into the side post of the battery. They've been sitting on my desk and I just have to grab a die and rethread them for 3/8" at the end.

So these Are not 3/8-16 thread?

 

[PAToyota]

The ones Will Scarlet linked (and I bought) are listed as 3/8" / M10: https://www.amazon.com/Battery-Ground-Junction-Connector-Terminal/dp/B089FF3185

They're M10 and 3/8" is 9.525mm, so I needed to clean them up with a die to get them to work. I suppose I could have used a tap on the battery as the other option, but then would have to retap a new battery.
