Wacker Neuson 5000175403 Lock Hex Nut M8-1.25 CL10.9

The Wacker Neuson is a genuine OEM Lock Hex Nut M8-1.25 CL10.9 designed for the Angle Broom 72" and Angle Broom 84" attachments. As a direct factory replacement, this fastener meets the exact torque and thread specifications required for secure, lasting assembly on these broom units. Sourcing the correct OEM part ensures the hardware performs as originally engineered, maintaining the structural integrity of the attachment under working loads.

Key Features

• Class 10.9 High-Strength Rating — Engineered to the CL10.9 grade, this nut delivers the clamping force and tensile strength needed to hold critical broom attachment components firmly under continuous vibration and load.
• Locking Thread Design — The locking feature resists loosening caused by operational vibration, keeping fastened joints secure over extended use cycles without frequent re-torquing.
• Correct M8-1.25 Thread Specification — Matches the exact thread pitch of the mating hardware on the Angle Broom, allowing straightforward installation without thread chasing or modification.
• Confirmed OEM Fitment — Verified genuine Wacker Neuson replacement part for the Angle Broom 72" and Angle Broom 84" attachments, so you can order with confidence using part number 5000175403.
• Prevents Joint Failure Risk — A worn, stripped, or missing lock nut can allow broom components to shift or separate during operation; replacing with the correct grade fastener restores a safe, rigid connection.

A lock hex nut is a fastener that threads onto a bolt or stud and uses a locking mechanism — such as a prevailing-torque nylon insert or a distorted thread profile — to resist backing off under vibration. On angle broom attachments, where operating conditions generate constant vibration and directional stress, maintaining proper clamp load at every fastening point is essential to keeping the assembly rigid and aligned. When a lock nut wears out, strips, or is missing entirely, the joint can loosen progressively, leading to misalignment, accelerated wear on surrounding components, or potential structural separation during use.
