The Wacker Neuson is a genuine OEM Screw M8 X 40 Hex Head Medium Loc designed for the CRT48 series ride-on concrete trowels. Sourced directly through Wacker Neuson's authorized parts program, this fastener is manufactured to the exact specification called out in the original assembly — ensuring correct thread engagement, head geometry, and medium-strength locking adhesive retention right out of the box. Confirmed fitment spans a wide range of CRT48 variants including the CRT48-35L, CRT48-35V, CRT48-37V, CRT48-34V, CRT48-31V, CRT48-33K, CRT48-33K DF, and CRT48-57K-MS, covering both standard and dual-fuel configurations.
Key Features
- OEM Thread and Head Specification — M8 x 40 hex head profile matches the original fastener exactly, providing correct torque transfer and seating depth without substitution or shimming.
- Medium-Strength Locking Compound Pre-Applied — The medium loc designation indicates a pre-applied thread-locking retention grade that resists vibration loosening under the demanding operating conditions of a ride-on trowel.
- Broad CRT48 Series Coverage — A single part number covers the CRT48-35L, CRT48-35V, CRT48-37V, CRT48-34V, CRT48-33K, CRT48-33K DF, CRT48-31V, and CRT48-57K-MS, simplifying parts ordering across your fleet.
- Direct-Fit Replacement — Installs into the original tapped bore with no thread chasing or rework required, getting your machine back into service faster after routine maintenance or component replacement.
- Genuine OEM Sourcing — Part number 5000157145 is an authentic Wacker Neuson component, meaning material grade and dimensional tolerances reflect the original engineering drawings for the CRT48 platform.
Hex head fasteners with a medium-strength locking compound are used throughout ride-on trowel assemblies to secure components that are subject to continuous vibration and load cycling during concrete finishing. The hex head format allows proper torque application with standard tooling, while the medium loc retention compound prevents the screw from backing out under operational vibration without sacrificing serviceability — unlike permanent-strength thread lockers, medium-grade retention still allows removal with standard hand tools during future servicing. When a fastener like this works loose or is replaced with an incorrect specification, it can lead to misalignment of attached components, accelerated wear on mating parts, and potential structural failure of the assembly it secures.
