Projecta BT14-N10 Negative Wingnut Brass Battery Terminal, Box of 10

Quick answer

The Projecta BT14-N10 is the Negative Wingnut Brass Battery Terminal, Box of 10. A wingnut lets you fit and remove ring lugs by hand, which suits accessories that come off now and then.

This is the 10 piece box of negative wingnut terminals, handy for workshops restocking the drawer. Lugs sit on a 5/16 inch or 8 mm stud. A wingnut lets you fit and remove ring lugs by hand, which suits accessories that come off now and then.

Material is forged brass, a solid choice for battery connections. Positive posts are slightly larger than negative posts, so fit this one only to the negative side.

Give the post a clean first; a dirty post will undo a good terminal.

If the old terminal was badly corroded, cut the cable back to clean copper before fitting the new one. Check the terminal again after the first week, as new cable can settle under the clamp. Tighten firmly but do not crush the post; a lead post deforms easily. Measure the post and the cable before ordering; a terminal that is too big for the post will never clamp properly. After fitting, a thin smear of terminal grease or spray protector slows corrosion.

FAQ

Before I order, how many negative terminals are in a BT14-N10?

All 10 are negative wingnut terminals, packed in one box.

Doing this in the driveway, will my 8 mm ring lugs fit the BT14-N10 stud?

The stud is 5/16 inch or 8 mm. Use lugs with a hole to match.

Doing this in the driveway, will a negative wingnut terminal fit the opposite post?

No. Positive posts are slightly larger than negative ones, so this negative terminal is sized for the negative post only.

Doing this in the driveway, should I put grease or spray on the BT14-N10 once it is on the negative post?

Yes. Once it is tight, a thin coat of terminal grease or protector spray over the joint slows corrosion.

Before I order, can I overtighten a wingnut terminal like the BT14-N10?

Tighten until it cannot be twisted on the post by hand. Going further risks damaging the post or the terminal.
