The stud is 5\/16 inch or 8 mm, so ring lugs need a matching hole. The bolt style holds ring lugs firmly with a nut, the usual choice where vibration is a concern.\u003c\/p\u003e\u003cp\u003eForged brass conducts well and copes with the heat and vibration of an engine bay. Positive posts are slightly larger than negative posts, so fit this one only to the negative side.\u003c\/p\u003e\u003cp\u003eClean the post back to bright metal before fitting, and coat the joint once tightened.\u003c\/p\u003e\u003cp\u003eTighten 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. 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.
