Wacker Neuson 5000069468 Screw B3.9 X 19

The Wacker Neuson is a genuine OEM Screw B3.9 X 19 designed for the IREN series internal concrete vibrators and associated FUE and KTU frequency converter units. Sourced directly from Wacker Neuson, this fastener matches the original equipment specification used on the production line, ensuring a correct and secure installation without the guesswork of adapting an off-spec alternative. Compatibility spans the full IREN lineup — including IREN 30, IREN 38, IREN 45, IREN 57, IREN 58, IREN 65, and IREN 65k models across a wide range of voltage and cable-length configurations — as well as FUE and KTU converter housings.

Key Features

• Correct Thread Form and Drive Type — Genuine OEM fastener manufactured to the exact thread pitch, head geometry, and material grade specified for IREN vibrator and converter assemblies, so it seats and clamps as intended.
• Direct Housing Replacement — Replaces the original Screw B3.9 X 19 in vibrator heads and converter enclosures with no reworking of the mounting boss or pilot hole required.
• Broad IREN and Converter Compatibility — Verified fitment across IREN 30, 38, 45, 57, 58, 65, and 65k internal vibrator families plus FUE 1, FUE 2, FUE 3, FUE 6, KTU 1, and KTU 2 frequency converters.
• Maintains Enclosure Integrity — A stripped, under-torqued, or wrong-pitch screw on a vibrator housing or converter case can allow moisture ingress and vibration-induced loosening; the correct OEM fastener keeps the assembly properly sealed and secured during operation.
• Electrical Safety Consideration — On converter units, housing fasteners retain covers that protect live internal components; using the specified screw ensures the enclosure is fully closed and compliant with the original design intent.

The Screw B3.9 X 19 is a self-tapping fastener used to secure housing panels, covers, and enclosure sections on Wacker Neuson IREN internal concrete vibrators and their companion FUE and KTU frequency converters. It holds the assembly together under the continuous vibration loads and handling stresses typical of active concrete placing work. When this fastener is missing, stripped, or replaced with an incorrect size, the housing can work loose, allowing dust, water, and concrete slurry to reach internal components — leading to premature failure of the vibrator motor or converter electronics. Replacing a damaged or lost screw promptly with the correct OEM part keeps the unit structurally sound and operating as designed.
