Buying for the workshop? The BT642-N10 puts 10 negative bolt terminals in one bag.\u003c\/p\u003e\u003cp\u003eBuying for the workshop? The BT642-N10 puts 10 negative bolt terminals in one bag. Stud size is listed as 5\/16 inch or 8 mm.\u003c\/p\u003e\u003cp\u003eLugs 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.\u003c\/p\u003e\u003cp\u003eCheck polarity before fitting: this suits the negative post only. Clean the post back to bright metal before fitting, and coat the joint once tightened.\u003c\/p\u003e\u003cp\u003eAfter 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. If the old terminal was badly corroded, cut the cable back to clean copper before fitting the new one. Tighten firmly but do not crush the post; a lead post deforms easily. Check the terminal again after the first week, as new cable can settle under the clamp. Measure the post and the cable before ordering; a terminal that is too big for the post will never clamp properly.
