The Wacker Neuson is a genuine OEM Screw 3/8-16 X 1-1/4 Soc Hd designed for the RD12-90 tandem roller series, including both the Solid ROPS and Foldable ROPS configurations. As a direct factory replacement, this fastener is manufactured to the exact thread specification, head geometry, and material grade called out in the original equipment design. Sourcing a genuine OEM fastener ensures the correct torque retention and seating depth are maintained wherever this screw is used in the roller assembly. Keep part number on hand to stay ahead of routine service and unplanned repairs on your RD12-90.
Key Features
- Genuine OEM Thread Specification — Manufactured to the exact 3/8-16 thread pitch and 1-1/4 inch length, ensuring consistent clamp load and proper torque values during installation.
- Socket Head Drive — The socket head (Soc Hd) profile accepts a hex key for high-torque fastening in recessed or tight-access locations on the RD12-90 frame and drum assembly.
- Direct Fitment for RD12-90 Configurations — Compatible with both the RD12-90 Solid ROPS and RD12-90 Foldable ROPS tandem roller variants, no thread chasing or modification needed.
- Structural Integrity Where It Counts — A correctly spec'd fastener maintains the clamping force that keeps critical roller components aligned and secure; an incorrect or worn screw can lead to loosening under vibration.
- Factory-Sourced Replacement — Supplied as a genuine Wacker Neuson part, matching the material grade and surface treatment of the original hardware used during production.
A socket head cap screw like the 5000171021 serves as a structural fastener that clamps and secures components within the machine's frame, drum, or accessory assemblies. The 3/8-16 coarse thread and socket head design are chosen for applications where high clamping force is needed and a hex key provides better torque control than an open wrench. When a fastener of this type stretches, strips, or is replaced with an incorrect size, it can cause joint loosening under the continuous vibration generated by a tandem roller during compaction, potentially leading to component misalignment or accelerated wear on surrounding parts.
