Wacker Neuson 1000020127 Nut Din985-M12-8 A2K P

The Wacker Neuson is a genuine OEM Nut Din985-M12-8 A2K P designed for the TH627. Sourced directly from Wacker Neuson, this fastener meets the exact grade and dimensional specification called out in the original parts list, ensuring it seats and torques correctly in the application it was engineered for. If you are servicing a TH627 and need to replace a fastener at the M12 position, part number is the correct OEM-specified component for the job.

Key Features

• OEM-Grade Fastener Material — Manufactured to DIN 985 standard in A2 stainless steel, delivering the corrosion resistance and mechanical grade consistency required for secure, long-term clamping load retention.
• Nylon-Insert Locking Profile — The prevailing-torque nylon insert prevents self-loosening under vibration — critical for equipment that generates continuous dynamic loads during operation.
• Exact M12 Thread Specification — Matched to the M12 thread pitch specified in the TH627 parts list, so it threads on cleanly without chasing or reworking the mating fastener.
• Confirmed TH627 Fitment — Listed directly against the TH627 (Spare Parts List 418-02), giving you confidence you are ordering the correct replacement rather than a near-match substitute.
• Genuine Wacker Neuson OEM Part — Carries the same part number, grade marking, and dimensional tolerances as the fastener installed at the factory, so the assembly performs as originally engineered.

A DIN 985 nylon-insert lock nut is a standard prevailing-torque fastener used throughout construction equipment assemblies to secure components subject to vibration and cyclic loading. The nylon insert creates friction against the bolt thread, resisting loosening without requiring adhesive or secondary locking hardware. When a lock nut loses its prevailing-torque characteristics — through wear, over-cycling, or corrosion — the joint can work loose gradually, leading to misalignment, accelerated component wear, or unexpected mechanical failure. Replacing worn or damaged lock nuts with the correct OEM-specified fastener restores the clamping integrity of the assembly and keeps the machine operating within its designed parameters.
