M6 Thread Male Brass Battery Terminal Charging Posts, M6 Battery Post Adapter (+/-) for Extension, Pack of 2

Thread first, because nothing else matters until it is right: this is an M6 male post. It screws down into a battery terminal that already carries an M6 threaded hole, and the thread is metric, not imperial. Match it once and the fitting is settled; get it wrong and no amount of force will make the part sit where it should.

Male, metric, and cut from brass

Three things separate this part from anything that resembles it, and the supplier puts all three in its opening lines. The thread is METRIC M6. The thread is male, which means the adapter supplies the stud and your battery has to supply the hole. The metal is brass. A pair arrives in the packet, one piece for each polarity. Where a battery presents studs instead of holes, or presents an imperial thread, this is not the part that will marry up to it.

What ends up sitting above the battery

Fitted, the adapter offers a tapered cone of the kind an ordinary top-post clamp is shaped to grip. The cone for positive measures 19 mm and the one for negative 17 mm, the usual difference between the two posts, and the reason a pair is not interchangeable end for end. For chemistry the supplier points at lead-acid packs and at lithium, and it credits the brass with strength, with conducting, and with slowing corrosion down.

Key features

• M6 metric male thread: screws into a terminal that already has an M6 threaded hole in it.
• Brass throughout: the supplier names brass as the material, in capitals, in its first line.
• Standard top post output: converts the threaded hole into the tapered post a conventional clamp expects.
• Cones sized by polarity: the positive measures 19 mm, the negative 17 mm, so each piece has its own side.
• Hand tight, hand loose: the supplier says the part can be tightened and slackened by hand.
• No modification called for: described as a direct fit, with nothing to cut or drill.
• Chemistries named: lead-acid batteries and lithium batteries, both of them listed.

Gaps in this description

• The search summary above calls this corrosion-proof. The description claims only reduced corrosion, and reduced is the word we are prepared to stand behind.
• Not one current figure and not one voltage figure is printed in this description, though carrying battery current is precisely what the adapter exists to do.
• No tightening torque is given. The supplier says hand tight is enough, which is guidance about effort, not a figure.
• The description gives no overall height, no across-flats size and no mass, so how far the post will stand proud of the terminal cannot be worked out here.
• Male and female versions of this style of adapter are easy to confuse when shopping. Check whether your terminal has a hole or a stud before ordering, because this one needs a hole.

An M6 threaded hole is a particular thing to find on a battery terminal, and this is the brass male post cut to suit it, turning that hole into a post an everyday clamp will close around.
