Wacker Neuson 1000085317 Hex Screw M8x55 8.8 A2C DIN931

The Wacker Neuson is a genuine OEM Hex Screw M8x55 8.8 A2C DIN931 designed for the BT48A vibratory rammer. As a direct factory replacement, this fastener meets the original DIN931 specification used during production, ensuring it seats and torques exactly as intended. Sourced directly from Wacker Neuson, part number delivers the confidence of a verified OEM component for a machine that depends on precisely secured assemblies to perform under demanding compaction loads.

Key Features

• DIN931-Compliant Grade 8.8 Tensile Strength — Manufactured to DIN931 standard with a grade 8.8 rating, delivering the clamping force and shear resistance required in high-vibration rammer applications.
• A2C Surface Finish for Corrosion Protection — The A2C coating provides a protective layer against moisture and jobsite contaminants, helping the fastener maintain thread integrity over its service life.
• Direct OEM Replacement with Verified Thread Specification — M8x55 thread dimensions match the original factory spec exactly, threading directly into existing mounting points on the BT48A without modification.
• Built for BT48A Rammer Applications — Confirmed fitment for the Wacker Neuson BT48A vibratory rammer, a compact trench and cohesive soil compaction machine subject to continuous high-frequency impact loads.
• Structural Integrity Under Continuous Vibration — Loose or incorrect fasteners on a vibratory rammer can lead to component shift, misalignment, or accelerated wear; a correctly spec'd OEM screw maintains the integrity of the assembly throughout operation.

A hex screw in a vibratory rammer such as the BT48A is not a passive fastener — it is subjected to continuous high-frequency shock loads that can rapidly fatigue an underspec'd or incorrect replacement. The M8x55 8.8 A2C DIN931 designation defines not just size but material grade, surface treatment, and thread geometry, all of which determine how securely a joined assembly stays together under operating stress. Using an incorrect fastener risks loosening, thread stripping, or component separation, which can compromise both machine performance and operator safety.
