The Multiquip 54516 Allen Head Cap Screw M16X55 is a genuine OEM fastener designed for the RW1404MR, RW1403HF, RW1504HF, and P33/24 series RAMMAX rollers. As a direct OEM replacement, this screw meets the exact thread pitch, head geometry, and torque specifications required by the original design. Confirmed fitment includes RW1404MR (S/N 326075 and up), RW1403HF, RW1504HF (up to S/N ), and P33/24 FR/FC/FCR and HHMR-BD with blade configurations. Sourcing the correct fastener by part number 54516 ensures the assembly seats and torques properly the first time.
Key Features
- Genuine OEM Fastener Grade — Manufactured to the exact metallurgical and dimensional spec of the original screw, ensuring correct clamping load and thread engagement for structural roller assemblies.
- M16X55 Dimensions for Direct Installation — M16 thread diameter and 55 mm length match the original bore and thread depth, allowing straightforward installation with a standard hex key without rework.
- Broad RAMMAX Roller Compatibility — Fits RW1404MR, RW1403HF, RW1504HF, and P33/24 series machines, covering both walk-behind and specialized roller configurations across the Multiquip RAMMAX lineup.
- Structural Integrity Under Vibration — Roller assemblies generate continuous vibration during compaction passes; a correctly spec'd fastener like 54516 maintains clamp force and prevents loosening or joint failure over extended operation.
- Critical Fastener Safety Relevance — Structural fasteners on compaction rollers are load-bearing components; using the OEM-specified screw grade and size supports safe machine operation and reduces the risk of assembly separation under working loads.
An Allen head cap screw — also known as a socket head cap screw — uses an internal hex drive to apply high clamping force in confined spaces where a standard wrench cannot reach. In roller assemblies, fasteners like the 54516 secure critical structural and mechanical components that must withstand constant vibration, impact loading, and the stresses of compaction work. When a fastener of the wrong grade, length, or thread pitch is used, it can strip, back out, or fail to develop adequate clamping force, leading to loosened assemblies and potential mechanical damage during operation.
