The Wacker Neuson Screw DIN6921-A M8x40 A2K 8.8 is a genuine OEM fastener designed for the BPS1550c, BPS2050c, and ZEN-C 20 series plate compactors. Sourced directly through Wacker Neuson's OEM supply chain, this screw is manufactured to the exact DIN6921 flange head standard in A2K-grade stainless-compatible steel at 8.8 tensile strength, ensuring it meets the same specification as the original hardware installed at the factory. Confirmed fitment covers both the BPS1550c and BPS2050c models across CE and CN configurations, as well as ZEN-C 20 single direction plates.
Key Features
- DIN6921 Flange Head Specification — Meets the exact dimensional and tensile standard (8.8 grade) required for secure clamping force across plate compactor assemblies.
- A2K-Grade Material Integrity — Manufactured in A2K-class corrosion-resistant steel, holding up to the vibration, moisture, and grime exposure inherent in plate compactor operation.
- Direct-Fit Replacement — M8x40 thread and flange geometry match the original mounting points on BPS and ZEN-C series machines, dropping straight in without reworking hardware or clearances.
- Multi-Model Compatibility — Fits BPS1550c and BPS2050c plate compactors (CE and CN variants) and ZEN-C 20 single direction plates, covering a broad range of Wacker Neuson compaction equipment.
- Maintains Clamping Integrity Under Vibration — The DIN6921 flange head distributes load across a wider bearing surface, resisting loosening under the continuous high-frequency vibration generated by plate compactors.
A DIN6921 flange head screw functions as a structural fastener that combines a standard hex bolt with an integrated serrated flange washer, eliminating the need for a separate washer and providing a larger, more stable clamping surface. In plate compactor applications, where intense vibration is a constant operating condition, this design is critical — the serrated flange bites into the mating surface to resist self-loosening, keeping assemblies tight and preventing premature wear or misalignment of attached components. A stripped, incorrect, or failed screw in these positions can compromise structural integrity and lead to component movement that accelerates wear elsewhere in the machine.
