Wacker Neuson 5000034837 Screw M8 x 30 10.9 Flat

The Wacker Neuson is a genuine OEM Screw M8 x 30 10.9 Flat designed for CT36 and CT48 walk-behind concrete power trowels and BFS floor saws. As a factory-original fastener, part number is manufactured to the exact grade, thread pitch, and head geometry specified by Wacker Neuson for these machines. This screw fits a wide range of CT36 and CT48 model variants — including the CT36-5A, CT36-6, CT36-8A, CT36-9, CT36-400E, CT48-8A, CT48-9, CT48-11A, CT48-13A-V, and CT36-X series — as well as the BFS 1350AL, BFS 1350ALS, and BFS 1350L floor saws. Sourcing the correct OEM fastener keeps critical assemblies properly torqued and structurally sound throughout the service life of your equipment.

Key Features

• Grade 10.9 High-Tensile Strength — Manufactured to the 10.9 property class, this fastener delivers the clamping force and shear resistance required for structural and mechanical assemblies on concrete finishing and cutting equipment.
• Genuine OEM Part — Sourced directly from Wacker Neuson, 5000034837 meets the exact material grade, thread specification, and dimensional tolerances called out in the original engineering drawings.
• Drop-In Replacement — M8 x 30 sizing and flat bearing surface match the original fastener geometry, seating flush against mating components without shimming or modification.
• Broad CT and BFS Fitment — Confirmed for CT36 and CT48 walk-behind power trowel families across gasoline and electric variants, plus BFS 1350AL, BFS 1350ALS, and BFS 1350L floor saws.
• Prevents Fastener Failure in High-Vibration Environments — Concrete trowels and floor saws operate under sustained vibration loads; using a correctly graded OEM fastener prevents loosening, fatigue cracking, and unplanned disassembly during operation.
• Torque-Critical Safety Application — Fasteners at this specification are commonly used in load-bearing or blade-guard assemblies where under-torquing or substituting a lower-grade screw creates a direct safety risk to the operator.

A metric hex cap screw rated to property class 10.9 is a high-tensile fastener engineered to withstand significant clamping loads without stretching or shearing. In concrete trowels and floor saws, fasteners like the 5000034837 secure rotating assemblies, guards, and structural brackets that are subjected to constant vibration and intermittent shock loads. When a fastener of this type loosens, corrodes, or is replaced with an incorrect grade, it can lead to component misalignment, structural failure, or a safety hazard — making like-for-like OEM replacement the correct service choice.
