The Multiquip 4571 is a genuine OEM HFS Screw M10-1.5 X 16 Class 8.8 designed for LD60, LD6, LD6SL, and PRX series ride-on power trowels. As a direct Multiquip OEM part, it is manufactured to the exact grade and dimensional spec required by these machines, ensuring a correct installation without guesswork. Sourced directly through authorized distribution, the 4571 is the right call when performing scheduled maintenance or mechanical repairs on your ride-on trowel.
Key Features
- Class 8.8 Grade Steel: — Meets the tensile and yield strength requirements for structural fastener applications on ride-on trowel assemblies, where hardware failures can compromise mechanical integrity.
- Correct Thread Specification: — M10-1.5 thread pitch and 16mm length match the OEM fastener profile, threading directly into existing bosses and mounts without chasing or re-tapping.
- Broad Trowel Family Fitment: — Compatible with LD60, LD6, LD6SL, and PRX ride-on power trowels, covering both the light-duty hydrostatic and hybrid power float series.
- Genuine OEM Part: — Manufactured to Multiquip's exact material and dimensional standards, providing the same hardware that ships with new machines from the factory.
- Structural Fastener Reliability: — Using the correct grade fastener in load-bearing and torque-sensitive joints helps maintain proper clamp force and prevents loosening under the vibration loads common to concrete finishing equipment.
An HFS screw is a hex flange screw — a metric fastener that combines a hex drive head with an integrated flange that distributes clamping load across a wider bearing surface without requiring a separate washer. On ride-on power trowels like the LD and PRX series, fasteners at this grade are used in mechanical assemblies where consistent clamp force is critical to keeping components properly secured under continuous vibration and operational stress. Using an incorrect grade or thread pitch can lead to fastener stretch, loosening, or thread damage, which may result in component misalignment or mechanical failure over time.
