Projecta BT14-2 Wingnut Brass Battery Terminal, 1 negative and 1 positive Pack

Quick answer

The Projecta BT14-2 is the Wingnut Brass Battery Terminal, 1 negative and 1 positive Pack. Mixed pack: 1 negative and 1 positive wingnut terminals, enough to redo both posts on 1 batteries.

Clean the post back to bright metal before fitting, and coat the joint once tightened.

Stud size is listed as 5/16 inch or 8 mm. With a wingnut on the stud, lugs can be swapped without a spanner.

Forged brass conducts well and copes with the heat and vibration of an engine bay.

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. Keep the positive covered so a spanner cannot bridge it to the body. Measure the post and the cable before ordering; a terminal that is too big for the post will never clamp properly. 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.

FAQ

How many positive and negative terminals come in the BT14-2 pack?

It holds 1 negative and 1 positive terminals, 2 in total.

What stud size does the BT14-2 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 BT14-2?

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 BT14-2 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 BT14-2 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.
