M8 Thread Brass Battery Terminal Charging Posts, Battery Post Adapter (+/-) with Solid M8 Bolts as Male Posts Direct to Battery, Pack of 2

You reach a battery terminal with the bonnet propped and one hand working in awkward space, so the thread size is the fact that decides everything before you get there. These posts are M8, metric, and male. The bolt is the male half, which means the terminal on your battery has to arrive already tapped to M8. Turn up with a different pitch and the job never begins.

Solid bolts, straight onto the post

Two details in the supplier's second line carry the weight. The bolts are described as solid, and they fix the adapters direct to the battery posts rather than through anything in between. Brass is the metal, capitalised in the opening line. Three separate claims are then hung on the adapter itself: added strength, conduction, and corrosion held down rather than shut out.

The shape you end up with above the hole

Driven home, each half stands up as a tapered post that an everyday clamp shuts around. The two are deliberately unequal, the plus side coming to 19 mm and the minus to 17, so the halves will not trade places. Battery chemistry is covered loosely, lead-acid and lithium both getting a mention, and the fitting is called direct with nothing needing modification. The install line goes no further than crediting that lack of modification with making the job faster and easier.

Key features

• M8 metric thread: male bolts, cut to drive into an M8 tapped hole in the terminal.
• Bolts called solid: the supplier's own word, and its reason they seat directly on the post.
• Brass, capitalised: the metal is named once, in the first line, and never qualified further.
• Threaded hole becomes a post: the output is the ordinary tapered shape a clamp expects.
• Sides sized apart: the plus half runs to 19 mm, the minus half to 17 mm.
• Two halves to a pair: a single pair, one half per polarity.
• Chemistries listed: lead-acid packs and lithium packs, both named.

Where the page runs out of information

• No amperage is quoted, and no voltage either, though carrying what the battery pushes through it is the one reason this hardware exists.
• No tightening figure is offered either. In its place the supplier remarks that fingers alone will tighten and loosen the joint, which describes effort rather than fixing a value, and we would not treat it as licence to leave a battery joint finger-tight.
• Nothing published here tells you to isolate the battery before you start work on it.
• The search blurb above calls these corrosion-resistant. The supplier's copy only claims corrosion is reduced, and reduced is the weaker of the two, so reduced is what we carry.
• The sizing sentence arrived with a character missing from an entity between the positive and negative figures. That is a Loss: a single character gone. Not a Gap, which is what you get when a connector vanishes but both spaces stay behind, and not a fusion either. The measurements either side came through intact, so they are rewritten above rather than quoted with the damage still in them.
• A second style sells at a higher price under a supplier code from a different family. Styles go unmentioned throughout the description, and nothing published tells the two apart.
• No height is given, no across-flats size, no mass at all, which leaves nothing to work out how much room the finished post needs above the battery.

An M8 threaded hole in the terminal is the one thing to confirm with a gauge before ordering, because every other decision about these brass posts follows from that single measurement.
