The Wacker Neuson Flange Screw is a genuine OEM flange screw designed for a wide range of Wacker Neuson compactors, plate compactors, and generators, including the GV2500A, BPU2540A, HP50A, VP series, WP series, and WPU series machines. Sourced directly from Wacker Neuson, this is the same part installed at the factory — no guesswork on specification or fitment. The covers an extensive list of VP1340, VP1550, VP2050, WP1540, WP1550, WPU1550, and related models, making it one of the more versatile fastener replacements in the Wacker Neuson lineup. When you need an exact match to restore your equipment correctly, this is the part to order.
Key Features
- Genuine OEM Fastener Integrity — Manufactured to Wacker Neuson's exact thread profile, shank diameter, and flange dimensions, ensuring the clamping load and torque spec are met every time.
- Drop-In Installation — Matches the original mounting points and thread engagement depth on all listed models, so the screw seats and torques correctly without rework.
- Broad Model Coverage — A single part number covers the GV2500A generator, BPU2540A plate compactor, HP50A, and the full VP1340, VP1550, VP2050, WP1540, WP1550, and WPU1550 series — both US and international variants.
- Structural Holding Power — A correctly fitted flange screw distributes clamping force evenly across the mating surface; a stripped or wrong-spec screw can allow component loosening under the vibration loads these machines generate.
- Direct Wacker Neuson Part — Part number 5100050456 is the OEM reference, so you can cross-check against your machine's parts diagram with confidence before ordering.
A flange screw combines a standard screw with an integrated wide-bearing flange at the head, which spreads the clamping load over a larger surface area without requiring a separate washer. On vibration-intensive equipment like plate compactors and generators, this design resists loosening and protects the mating material from damage. When a flange screw wears, strips, or is replaced with an incorrect fastener, the joint can work loose under load — leading to misalignment, component damage, or accelerated wear on surrounding parts.
