Projecta BT642H-N10 Negative Heavy Duty Bolt Brass Battery Terminal, Bag of 10

Quick answer

The Projecta BT642H-N10 is the Negative Heavy Duty Bolt Brass Battery Terminal, Bag of 10. It is the heavy duty version, built for the bigger cable sizes used on 4WD, truck and dual battery work.

Bag 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.

Stud size is listed as 3/8 inch or 10 mm. The bolt style holds ring lugs firmly with a nut, the usual choice where vibration is a concern. Material is forged brass, a solid choice for battery connections.

Check polarity before fitting: this suits the negative post only. 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. 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.
