Wacker Neuson 5000011454 Screw M8 X 40 Hex Head

The Wacker Neuson Screw M8 X 40 Hex Head is a genuine OEM fastener designed for a wide range of Wacker Neuson equipment, including BFS floor saws, CT and CRT concrete trowels, G-Series portable generators, and WP and VP vibratory plate compactors. Sourced directly from Wacker Neuson, this fastener meets the exact thread pitch, length, and tensile specifications called out in the original equipment build. With coverage spanning dozens of machine configurations across multiple product families, part number is a high-demand hardware item worth keeping on hand. Confirm fitment using your machine's serial number before ordering.

Key Features

• Genuine OEM Tensile Specification — manufactured to the exact M8 x 40 thread and grade specification Wacker Neuson uses in production, ensuring consistent clamping torque across all covered assemblies.
• Hex Head Drive — the hex head profile accepts standard metric wrenches and sockets, allowing fast installation and proper torque application without specialized tooling.
• Broad Cross-Family Fitment — a single part number covers BFS floor saws, CT and CRT concrete trowels, G-Series skid-mounted and mobile generators, WP and VP vibratory plates, and select battery-powered rammers, making it a versatile stocking item for mixed fleets.
• Structural Integrity at the Joint — a correctly torqued OEM-spec fastener maintains proper clamping load on covers, guards, and structural panels; a stripped, corroded, or under-spec replacement can allow components to shift or vibrate loose under operating loads.
• Safety-Critical Hardware — fasteners securing guards, blade housings, and engine covers on floor saws and trowels are subject to vibration and must meet the original grade specification; substituting a lower-grade screw risks guard displacement during operation.

An M8 x 40 hex head screw is a metric fastener with an 8 mm thread diameter and a 40 mm shank length, driven by a hex head for high-torque installation. In construction equipment, fasteners at this size class are commonly used to secure protective covers, structural brackets, engine mounts, and housing panels — areas where correct clamping force directly affects both mechanical integrity and operator safety. When a fastener fails, stretches, or is replaced with an out-of-spec substitute, the clamped joint can loosen progressively under vibration, potentially allowing guards or panels to shift out of position. Using the correct OEM part number ensures the thread engagement, shank strength, and head geometry all match the original design intent.
