Projecta BT14-10 Wingnut Brass Battery Terminal, 5 negative and 5 positive Pack

Quick answer

The BT14-10 gives you 5 negative and 5 positive wingnut terminals, so one pack covers both posts on several batteries.

The BT14-10 gives you 5 negative and 5 positive wingnut terminals, so one pack covers both posts on several batteries. Forged brass conducts well and copes with the heat and vibration of an engine bay.

Before fitting, clean any corrosion off the post so the terminal seats properly. Lugs sit on a 5/16 inch or 8 mm stud.

With a wingnut on the stud, lugs can be swapped without a spanner.

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

FAQ

How many positive and negative terminals come in the BT14-10 pack?

It holds 5 negative and 5 positive terminals, 10 in total.

What stud size does the BT14-10 have for ring lugs?

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

My old wingnut terminal is cracked; can I just swap in the BT14-10?

Cut the cable back to clean, bright copper if the old end is green or black, then fit the new terminal and tighten it firmly.

Should I put grease or spray on the BT14-10 once it is on the mixed post?

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

How tight should the BT14-10 be on the battery post?

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