The Wacker Neuson Flange Screw 5x8 is a genuine OEM flange screw designed for the BS50-4As, BS60-4As, BS65-4As, BS70-4As, BS72-4As, BS62-4Ab/28, BS68-4Ab/28, and related 4-stroke rammer series. As a direct factory-sourced component, matches the original thread specification, flange diameter, and head geometry used in production — so it installs exactly as intended without guesswork. This screw is used across a wide range of BS-series rammer configurations, including US, CN, and Sunbelt variants, making it a versatile stocking part for fleet operators and rental houses alike. Keep a spare on hand and you'll have a fast, straightforward fix whenever a fastener needs replacing in the field.
Key Features
- OEM Thread and Flange Specification — Sourced directly from Wacker Neuson, this screw meets the exact thread pitch, shank length, and integrated flange bearing surface called out in the original build spec for BS-series rammers.
- Drop-In Installation — The flange head seats flush against mating surfaces without the need for a separate washer, keeping the assembly clean and correctly torqued every time.
- Broad BS-Series Compatibility — Confirmed fit across BS50-4As, BS60-4As, BS65-4As, BS70-4As, BS72-4As, BS62-4Ab/28, BS68-4Ab/28, and multiple regional variants, covering a large portion of the Wacker Neuson 4-stroke rammer lineup.
- Maintains Structural Integrity — A correctly torqued flange screw keeps critical covers, guards, and components securely fastened under the high-vibration operating conditions rammers generate with every stroke.
- Genuine OEM Traceability — Part number 5100049221 is the authorized Wacker Neuson part number, so you can cross-reference it against your service manual with confidence before ordering.
A flange screw combines a standard threaded fastener with an integrated wide-diameter flange beneath the head, which distributes clamping load evenly across the mating surface without requiring a separate washer. On a vibratory rammer, fasteners are subjected to constant, high-frequency impact forces that can work loose conventional hardware over time — the flange design resists this by increasing the contact area and improving resistance to loosening under vibration. When a flange screw fails, becomes stripped, or goes missing, the component it secures can shift, rattle, or detach entirely, leading to accelerated wear on surrounding parts and potential downtime on the compaction site.
