Industrial M16-2.0 x 80 Hex Head Flange Bolts

Description:

The Unknown M16-2.0 × 80 Hex Head Flange Bolts with Flange Locknuts are used to provide secure, high-strength fastening in industrial machinery, structural assemblies, and mechanical equipment. Commonly installed in heavy equipment, conveyors, construction machinery, agricultural equipment, and industrial fabrication projects requiring vibration-resistant bolted connections. Maintenance technicians, mechanics, and system integrators use these fasteners for equipment repair, machine assembly, structural maintenance, and replacement of worn or damaged metric hardware.

Applications:

These Unknown M16 × 2.0 × 80 mm hex head flange bolts are designed to provide reliable clamping force while the integrated flange distributes the load over a larger surface area, reducing the need for separate washers. When paired with matching M16 flange locknuts, they help resist loosening caused by vibration and dynamic loads, making them suitable for industrial machinery, mining equipment, automotive assemblies, steel structures, material handling systems, and general-purpose heavy-duty fastening applications.
