The 082V03216-8316 Hex Flange Bolt is a Grade 10.9 high-strength fastener purpose-built for Sinotruk's MAN-derived engine platforms. At 136 millimeters overall length, this bolt is noticeably longer than its 105mm sibling (part number 082V03216-8315), and that extra length matters — it's engineered for specific engine assemblies where a shorter fastener simply won't engage enough threads to hold torque under diesel-engine vibration and thermal cycling.
