Wacker Neuson 5100054661 Screw M12x40 Socket Head 10.9 Zinc

The Wacker Neuson Screw M12x40 Socket Head 10.9 Zinc is a genuine OEM fastener designed for the HTC15 Trench Roller. As a direct Wacker Neuson OEM part, is manufactured to the exact grade, thread pitch, and zinc coating specification required by the machine — no guesswork on strength class or corrosion protection. If you're servicing or reassembling an HTC15, this is the correct fastener to reach for. Sourcing the right hardware grade matters: substituting an incorrect strength class or coating can compromise joint integrity under the dynamic loads a trench roller generates.

Key Features

• Grade 10.9 High-Tensile Rating — Manufactured to property class 10.9, delivering the clamping force and fatigue resistance required for structural and drivetrain fastening applications on compaction equipment.
• Zinc Coating for Corrosion Resistance — ZnC surface treatment guards against rust and oxidation in the wet, muddy environments trench rollers routinely operate in, helping threads stay clean and removable at the next service interval.
• Internal Hex Drive — Socket head configuration allows precise torque application with a hex key or socket driver, reducing the risk of rounding in confined or recessed fastening locations.
• Exact OEM Specification — Supplied as a genuine Wacker Neuson part, matching the M12x40 dimensions, thread form, and material spec called out in the original assembly documentation.
• Direct Fitment for HTC15 Trench Roller — Confirmed fitment for the HTC15 series, so you're ordering with confidence rather than cross-referencing generic hardware charts.

A socket head cap screw is a high-strength threaded fastener used to clamp components together in assemblies where a flush or recessed installation is needed and precise torque control matters. On a trench roller like the HTC15, fasteners at this strength grade are typically used in load-bearing joints — such as drive system housings, frame connections, or drum assemblies — where vibration and ground-reaction forces place repeated stress on the joint. Using a fastener with the wrong strength class or a corroded thread can allow joint movement, accelerate wear on mating components, or lead to unexpected fastener failure during operation.
