The Wacker Neuson is a genuine OEM Hexagonal Flange Head Screw designed for the RD7 series walk-behind tandem rollers. Sourced directly from Wacker Neuson, this fastener meets the exact specifications used in original production, ensuring a correct fit across the full RD7 family including RD7A, RD7H, RD7He, and RD7Ye variants. Whether you're servicing a standard RD7 Tandem Roller or a North America-spec RD7He, this is the correct OEM part for the job.
Key Features
- Genuine OEM Fastener Grade — Manufactured to Wacker Neuson's original torque and thread specification, ensuring the correct clamping force for the specific joint it secures on the RD7 tandem roller.
- Integrated Flange Design — The built-in flange distributes load evenly across the mating surface, eliminating the need for a separate washer and locking the fastener securely during operation.
- Broad RD7 Series Coverage — Compatible with RD7, RD7A, RD7H, RD7He, and RD7Ye walk-behind tandem rollers across multiple serial number ranges, including North America-only configurations.
- Vibration-Resistant Holding Power — The flanged hex head resists loosening under the continuous vibration inherent to tandem roller operation, maintaining structural integrity between service intervals.
- Direct OEM Replacement — Matches the original part pulled from the machine, so installation follows the same procedure as the factory-fitted fastener with no alterations to surrounding components.
A hexagonal flange head screw combines a standard hex bolt with an integrated circular flange beneath the head that acts as a built-in bearing surface. On vibratory compaction equipment like the RD7 tandem roller, fasteners are subjected to constant mechanical vibration, which can cause standard bolts to back out over time. The flanged head increases the contact area against the joint face, improving grip and resistance to loosening without relying on an additional washer. A missing, stripped, or under-torqued screw in a high-vibration assembly can lead to component misalignment, accelerated wear on surrounding parts, or structural failure at the joint — making like-for-like OEM replacement the safest and most reliable service choice.
