The Wacker Neuson Countersunk Bolt M12x135 is a genuine OEM countersunk bolt designed for the BS62, BS68, AS62, and AS68 series rammers and vibratory compactors. As a direct OEM replacement, part is manufactured to the exact dimensions and thread specification required by these machines, ensuring a correct fit at installation without the guesswork of cross-referencing aftermarket alternatives. This bolt is confirmed compatible across a wide range of BS62 and BS68 rammer configurations as well as AS62 and AS68 electric rammer variants. When you need a hardware replacement you can trust, sourcing the genuine Wacker Neuson part keeps your machine running to its original design standard.
Key Features
- OEM Thread and Dimensional Accuracy — Manufactured to the exact M12x135 thread pitch and shank length specified for these rammer models, eliminating the risk of stripped threads or misalignment during reassembly.
- Countersunk Head Profile — The flush-seating countersunk head seats correctly in its designated bore, maintaining proper clamping load and preventing proud hardware from interfering with adjacent components.
- Broad Series Compatibility — Fits BS62-2, BS62-4A, BS68-2, BS68-4A, AS62e, AS68e, AS62ve, and AS68ve variants, covering a wide cross-section of Wacker Neuson rammer and electric rammer product lines.
- Structural Integrity Under Impact Load — Rammers operate under repeated percussive force; using a correctly rated OEM bolt at this location maintains the structural connection it secures and prevents fastener fatigue failures in the field.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, this bolt carries the same part number — 5100062090 — used by authorized service centers, so you can order with confidence in what you're receiving.
A countersunk bolt is a threaded fastener with a tapered, flat-angled head designed to sit flush with or below the surface of the material it secures. In rammer and compactor applications, fasteners like the M12x135 countersunk bolt bear significant dynamic loads generated by the machine's percussion mechanism during operation. A worn, stretched, or incorrect bolt at this location can compromise the structural integrity of the assembly it holds together, leading to loosening, vibration-induced damage, or component separation during use. Replacing a failed or damaged bolt with the correct OEM specification part restores the connection to its designed clamping force and keeps the machine operating safely.
