This is a hex flange bolt with M12 x 1.75 mm threads and a 40 mm length. It's a heavy-duty fastener used to secure components on medium and heavy-duty trucks. You'd replace it when the original bolt is stripped, corroded, broken, or lost during servicing of the engine, chassis, or power generation equipment.
