Multiquip 012012020 Hex Plain Screw 12X20 DIN#933 85Ssk/Ssm

The Multiquip 012012020 is a genuine OEM Hex Plain Screw 12X20 DIN#933 85Ssk/Ssm designed for RAMMAX walk-behind roller models including the RW1403HF, RW1404, RW1404MR, RW1504HF, RW1810, and RW3010. As a factory-original fastener, it meets the exact dimensional and material specifications called out in the Multiquip parts documentation for these machines. Sourced directly through authorized Multiquip distribution channels, 012012020 ensures a correct installation with no guesswork on sizing or grade.

Key Features

• Genuine OEM Grade Fastener — Manufactured to the DIN#933 standard in 85Ssk/Ssm stainless specification, delivering the correct thread form, shank diameter, and head dimensions for secure, torque-rated assembly.
• Direct Bolt-In Replacement — Matches the original thread pitch, length, and hex drive of the factory screw, so installation requires only standard hand tools with no rework or modification to mating components.
• Broad RAMMAX Roller Compatibility — Confirmed fitment across RW1403HF, RW1404, RW1404MR, RW1504HF (up to S/N 1534188), RW1810, and RW3010 walk-behind roller models.
• Corrosion-Resistant Stainless Material — The 85Ssk/Ssm stainless grade resists rust and surface degradation in wet or outdoor compaction environments, extending service life over standard carbon steel hardware.
• Structural Integrity Under Vibration — A properly spec'd fastener maintains clamping force through the continuous vibration loads that walk-behind rollers generate; an incorrect or worn screw can back out and cause component loosening or failure.

A hex plain screw is a standard externally threaded fastener used throughout a machine's structural and mechanical assemblies to clamp components together and maintain alignment under load. On vibratory rollers like the RAMMAX RW series, fasteners are subjected to sustained vibration cycles that can work loose incorrect or underspec'd hardware over time, leading to component shift, accelerated wear on adjacent parts, or assembly failure. Using the correct OEM-specified screw — with the right thread standard, length, and material grade — is essential to maintaining the structural integrity of the roller during operation.
