The Wacker Neuson 5100020174 is a genuine OEM Allen Screw designed for the RD7H and RD7He series walk-behind tandem rollers. Sourced directly from Wacker Neuson, this fastener meets the exact specifications of the original hardware used in production assembly. It is confirmed compatible across multiple RD7H and RD7He configurations, including North America-specific variants of the RD7He double-drum roller. When you need a straight-swap replacement that installs without guesswork, this is the correct part for the job.
Key Features
- Genuine OEM Hardware Grade — Manufactured to the precise thread pitch, drive depth, and hardness spec of the original fastener, so torque loads are transferred correctly without stripping or backing out.
- Drop-In Installation — Matches the original socket drive size and thread profile, seating exactly as the factory fastener did with no chasing or re-tapping required.
- Broad RD7 Series Coverage — Fits RD7H and RD7He tandem rollers across a wide range of machine numbers, including walk-behind and North America-only double-drum variants.
- Structural Integrity Where It Counts — A correctly spec'd Allen screw keeps critical assemblies clamped at the right preload; an incorrect or worn fastener can allow components to shift under the vibration loads typical of tandem roller operation.
- Verified Part Number — Order with confidence using Wacker Neuson part number 5100020174, cross-referenced to confirmed RD7H and RD7He fitment data.
An Allen screw — also called a socket head cap screw or hex socket screw — is a threaded fastener driven by a hexagonal (Allen) key inserted into a recessed socket in the head. On walk-behind tandem rollers like the RD7H and RD7He, these fasteners are used throughout the machine to clamp covers, mount components, and secure assemblies subject to continuous vibration. Because tandem rollers generate sustained vibratory forces during asphalt and soil compaction passes, fasteners in these applications must maintain consistent clamping load cycle after cycle. A fastener that is the wrong grade, stripped, or undersized can back out under vibration, leading to loose assemblies, accelerated wear on adjacent components, or unplanned stoppage on the job.
