Bolt

The Terex Bolt 3/8 UNF x 1.3/4 (OEM 57-7) is a replacement fastening bolt designed for compatible Terex and Benford site dumpers. It provides a secure threaded connection for components within the machine's mechanical assemblies, with its 3/8-inch UNF thread and 1.3/4-inch length suited to the original fastening arrangement.

Manufactured for the demanding conditions of construction and site equipment, the bolt provides dependable mechanical retention where vibration and repeated machine movement are present. It is used within the handbrake and linkage assembly of compatible Terex 5, 6 and 7 tonne dumpers, where it works with the associated washer and nut to secure the linkage components.
