Wacker Neuson 5000011327 Screw M10 x 85 Hex Head

The Wacker Neuson Screw M10 x 85 Hex Head is a genuine OEM fastener designed for a wide range of Wacker Neuson walk-behind concrete power trowels and vibratory trench rollers. This part covers CT36 and CT48 series trowels — including the CT36-5A, CT36-6, CT36-8A, CT36-9, CT36-400E, CT36-X, CT48-8A, CT48-9, CT48-11A, and CT48-13A-V — as well as the RT560 and RT820 vibratory trench rollers and RS800 series single-drum vibratory rollers. As a genuine Wacker Neuson component, part is manufactured to the exact dimensions and grade specification of the original hardware, ensuring a drop-in fit with no guesswork. Keeping correct fasteners on hand means critical assemblies stay torqued and secure through the demanding vibration loads these machines generate during operation.

Key Features

• Genuine OEM Grade Hardware — Manufactured to the exact thread pitch, shank length, and tensile grade of the original M10 x 85 hex head screw, so clamping force and torque retention meet design intent.
• Hex Head Drive for Positive Wrench Engagement — The hex head profile allows full torque to be applied with a standard wrench or socket, making installation straightforward in confined assembly areas.
• Broad CT36 and CT48 Trowel Coverage — Fits the full CT36 and CT48 walk-behind concrete power trowel lineup, spanning gasoline, electric, and variable-pitch variants across multiple serial ranges.
• RT560 and RT820 Trench Roller Fitment — Also confirmed for RT560 and RT820 vibratory trench rollers and RS800 series single-drum rollers, consolidating one fastener across multiple machine families.
• Vibration-Resistant Fastening — Correct thread engagement and shank length are critical on trowel and compaction equipment, where continuous vibration can cause undersized or worn fasteners to back out and compromise structural integrity.

A hex head cap screw like the 5000011327 serves as a structural fastener that clamps and secures major assemblies — such as guard brackets, handlebar mounts, frame components, and roller housings — against the sustained vibration loads generated during concrete finishing and soil compaction. The M10 x 85 designation specifies both the thread diameter and the full shank length, meaning the correct screw must be used to achieve full thread engagement in the receiving bore or nut. When a fastener of this type is missing, stripped, or substituted with an incorrect length or grade, clamped joints can work loose, leading to excessive play, premature wear on mating components, or a safety concern for the operator.
