Wacker Neuson 5100001329 Oval Head Screw

The Wacker Neuson Oval Head Screw is a genuine OEM fastener designed for the IREN, IRSE-FU, IRSEN, and IRSEN-FU series internal concrete vibrators. As a direct factory replacement, this screw matches the original specification and installs exactly as the part it replaces — no guesswork, no adaptation. It is confirmed to fit an extensive range of models across the IREN 30, 38, 45, 57, 58, and 65 families, as well as IRSE-FU and IRSEN variants covering both 115 V and 230 V configurations. Sourcing the correct OEM fastener ensures the housing or assembly it secures is held to the designed torque and seating profile, maintaining the integrity of the vibrator unit on the job.

Key Features

• OEM Thread and Head Geometry — Manufactured to Wacker Neuson's original thread pitch, shank diameter, and oval head profile, ensuring correct seating and clamping force in the vibrator housing.
• Drop-In Replacement — Matches the original fastener position and drive type for straightforward installation without reworking mounting holes or adjacent components.
• Broad IREN / IRSE / IRSEN Compatibility — Fits a wide range of Wacker Neuson internal concrete vibrator models across the IREN 30, 38, 45, 57, 58, and 65 series, plus IRSE-FU and IRSEN variants in multiple voltage configurations.
• Structural Integrity of the Vibrator Assembly — A correctly torqued fastener keeps housing panels and covers aligned and sealed; a stripped or incorrect screw can allow vibration-induced movement that damages surrounding components over time.
• Genuine OEM Confidence — Supplied as a factory-authorized Wacker Neuson part, backed by the same quality controls applied to new-unit production.

The Oval Head Screw is a structural fastener used to secure housing panels, covers, or internal assemblies within Wacker Neuson internal concrete vibrators. Its oval head profile distributes clamping load evenly across the mating surface, resisting the continuous vibration forces that these machines generate during concrete consolidation work. When this fastener is missing, stripped, or substituted with an incorrect type, the housing components it holds can shift or loosen under load, potentially leading to accelerated wear of seals, bearings, or cable entries and reducing the effectiveness of the vibrator in consolidating concrete.
