The Multiquip 12151 is a genuine OEM HHC Screw 3/4-10 x 2-3/4 designed for STH series hydrostatic ride-on trowels. As a direct factory replacement, this fastener matches the original thread pitch, diameter, and length specification required for critical assembly points on these machines. Sourced directly through authorized Multiquip supply channels, the part ensures you are installing the correct hardware the first time. DHS Equipment stocks this part to support contractors who need an exact-spec fastener to keep their finishing equipment back in service fast.
Key Features
- Correct Thread Specification — 3/4-10 UNC thread form and 2-3/4 inch length match the original fastener spec, ensuring full thread engagement without risk of stripping or under-torquing.
- Genuine OEM Construction — Manufactured to Multiquip's original material and hardness grade for a hex head cap screw used in structural and drivetrain assembly applications on heavy finishing equipment.
- Direct Assembly Fit — Drops into the same bolt pattern and seating surface as the original, requiring no modification to mating components or hardware.
- STH Series Compatibility — Verified fitment for STH hydrostatic ride-on trowels, covering the platform's common fastener applications across blade, frame, and drive system assemblies.
- Structural Integrity Assurance — A worn, stripped, or incorrectly sized fastener in a high-load trowel assembly can compromise blade pitch control and frame rigidity; the correct-spec replacement restores full clamping force.
A hex head cap screw such as the Multiquip 12151 serves as a primary structural fastener in load-bearing and vibration-exposed assemblies on ride-on trowel equipment. At the 3/4-10 UNC specification, it is sized for high-clamping-force applications where maintaining precise torque and thread engagement is critical to keeping major components securely positioned during operation. When a fastener of this size is damaged, corroded, or substituted with an off-spec replacement, it can lead to joint loosening under the repetitive stress of troweling cycles, creating safety and performance risks that are easily avoided by using the correct OEM part.
