AUTOMANN Flange Bolt Metric 16mm-2 x 70mm Part No: M5387

When you need a high-strength bolt for demanding applications, the M5387 flange bolt is engineered to perform. Supplied by Wofford Truck Parts, this metric fastener measures M16 with a 2.0 mm thread pitch and 70 mm length, and is manufactured to grade 10.9 specification—making it capable of withstanding elevated clamping loads and heavy vibration environments. Its flange head design improves load distribution and reduces the risk of joint loosening. Commonly used in securing major assemblies such as motor mounts (e.g., with part M17499) on heavy trucks like Peterbilt, this bolt is a reliable choice for maintenance and repair operations requiring OEM-equivalent hardware. Thread-locking is recommended in high-stress, vibration-prone environments to maintain preload and longevity.
