Wacker Neuson 5100001330 Oval Head Screw

The Wacker Neuson Oval Head Screw is a genuine OEM fastener designed for the IREN, IRSEN, and IRSE-FU series internal concrete vibrators. As a direct OEM replacement, this screw is manufactured to the exact specifications required by Wacker Neuson for use across a broad range of internal vibrator models and configurations. This part fits an extensive lineup of IREN and IRSEN vibrator heads spanning 30 mm through 65 mm diameter classes, as well as IRSE-FU converter-equipped units operating on 115 V, 120 V, 230 V, and 250 V supplies. Ordering by the verified part number ensures you receive the correct fastener for your specific unit.

Key Features

• Genuine OEM Fastener Integrity — Manufactured to Wacker Neuson's exact thread form, head geometry, and material spec, ensuring the oval head seats flush and holds torque correctly in the vibrator housing.
• Direct-Fit Replacement — Drops into the same mounting position as the original, with no rework or re-drilling required on the vibrator head or converter body.
• Broad Series Coverage — Fits IREN 30 through 65 mm diameter internal vibrators, IRSEN high-frequency models, and IRSE-FU converter-integrated units across multiple voltage configurations and hose lengths.
• Structural Security for High-Vibration Environments — Internal concrete vibrators operate under continuous cyclic loading; a correctly specified screw maintains housing integrity and prevents loosening or housing separation during operation.
• Verified Part Number — Cross-reference 5100001330 against your model number before ordering to confirm the right fastener for your vibrator variant, voltage, and hose length configuration.

The oval head screw on a Wacker Neuson internal concrete vibrator serves as a precision housing fastener, securing the vibrator head or converter body components together under the continuous mechanical stress of high-frequency vibration. Because internal vibrators cycle at several thousand vibrations per minute during concrete consolidation work, any fastener that does not meet the correct thread engagement depth, head profile, or material hardness can work loose, leading to housing misalignment, ingress of concrete slurry, or complete separation of the assembly in the field. Replacing a worn or damaged oval head screw with the correct OEM part restores the structural integrity of the vibrator unit and keeps the head operating at rated performance throughout the pour.
