Projecta BT614H-N10 Negative Heavy Duty Wingnut Brass Battery Terminal, Bag of 10

Quick answer

The Projecta BT614H-N10 is the Negative Heavy Duty Wingnut Brass Battery Terminal, Bag of 10. Heavy duty pattern, so it suits thicker starter and dual battery cable.

Bag of 10 negative heavy duty wingnut terminals, so this one is aimed at workshops restocking the drawer rather than a single car. Heavy duty pattern, so it suits thicker starter and dual battery cable.

Marked negative, it is sized for the negative post; the two are not interchangeable. Give the post a clean first; a dirty post will undo a good terminal. Stud size is listed as 3/8 inch or 10 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.

Keep the positive covered so a spanner cannot bridge it to the body. Tighten firmly but do not crush the post; a lead post deforms easily. If the old terminal was badly corroded, cut the cable back to clean copper before fitting the new one. After fitting, a thin smear of terminal grease or spray protector slows corrosion.
