Projecta BT14H-N10 Negative Heavy Duty Wingnut Brass Battery Terminal, Box of 10

Quick answer

The Projecta BT14H-N10 is the Negative Heavy Duty Wingnut Brass Battery Terminal, Box of 10. Heavy duty pattern, so it suits thicker starter and dual battery cable.

This is the 10 piece box of negative heavy duty wingnut terminals, handy for workshops restocking the drawer. Heavy duty pattern, so it suits thicker starter and dual battery cable.

Stud size is listed as 3/8 inch or 10 mm. 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.

Check polarity before fitting: this suits the negative post only. Clean the post back to bright metal before fitting, and coat the joint once tightened.

Keep the positive covered so a spanner cannot bridge it to the body. 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. 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

Fitting it myself, are all 10 terminals in the BT14H-N10 negative?

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

Quick question: will 10 mm ring lugs fit on the BT14H-N10?

The stud is 3/8 inch or 10 mm. Use lugs with a hole to match.

From the workshop: will a negative heavy duty 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.

Just checking, how do I stop the heavy duty wingnut BT14H-N10 going green on the post?

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 heavy duty wingnut terminal like the BT14H-N10?

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