Projecta BT142H-N10 Negative Heavy Duty Bolt Brass Battery Terminal, Box of 10

Quick answer

The Projecta BT142H-N10 is the Negative Heavy Duty Bolt Brass Battery Terminal, Box of 10. It is the heavy duty version, built for the bigger cable sizes used on 4WD, truck and dual battery work.

Box of 10 negative heavy duty bolt terminals, so this one is aimed at workshops restocking the drawer rather than a single car. It is the heavy duty version, built for the bigger cable sizes used on 4WD, truck and dual battery work. The stud is 3/8 inch or 10 mm, so ring lugs need a matching hole.

Lugs are held by a nut on the bolt, so tighten it with a spanner and it stays put. Forged brass conducts well and copes with the heat and vibration of an engine bay.

Marked negative, it is sized for the negative post; the two are not interchangeable. Before fitting, clean any corrosion off the post so the terminal seats properly.

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. 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 BT142H-N10 negative?

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

Doing this in the driveway, which lug hole size suits the negative heavy duty bolt BT142H-N10?

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

Just checking, will a negative heavy duty bolt 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.

From the workshop: is a terminal protector worth using over a BT142H-N10?

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

Doing this in the driveway, how tight should the BT142H-N10 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.
