The Multiquip 16056 is a genuine OEM Screw HHC M10-1.5X25MM GR 8.8 designed for Multiquip MTX rammers and Whiteman STX and HTX series ride-on power trowels. As a factory-sourced component, part 16056 meets the exact grade and thread specification required for these machines. Verified fitment includes MTX50HD, MTX60HD, MTX70HD, MTX70HDR, MTX80HDR, STX55Y6, STX55J6, STX D6i, HTX D6i, HTX44Y4, and HTX44Y5 models. Sourcing the correct OEM fastener ensures structural integrity is maintained wherever this screw is used in the assembly.
Key Features
- Grade 8.8 Tensile Strength — Manufactured to metric Grade 8.8 specification, providing the shear and clamping load capacity required for dynamic compaction and troweling equipment.
- Exact Thread Form — M10-1.5 thread pitch matches the tapped bores in MTX and STX/HTX assemblies, threading in cleanly without rework or chasing.
- Genuine OEM Sourcing — Supplied directly from Multiquip, ensuring the alloy grade, head dimensions, and thread tolerance match what left the factory originally.
- Broad Confirmed Fitment — Covers MTX50HD, MTX60HD, MTX70HD, MTX70HDR, MTX80HDR, STX55Y6, STX55J6, STX D6i, HTX D6i, HTX44Y4, and HTX44Y5 with a single part number.
- Structural Consistency — Using the correct fastener grade prevents joint loosening or fatigue cracking under the sustained vibration loads generated by rammers and ride-on trowels.
A hex head cap screw like the Multiquip 16056 is a structural fastener used to clamp and secure major assemblies — such as engine mounts, frame brackets, or drivetrain housings — together under controlled torque. The Grade 8.8 designation defines its minimum yield and tensile strength, making it suited to joints that experience vibration, impact, or repeated loading cycles. Substituting a lower-grade or incorrect-pitch fastener in these locations risks joint loosening, bolt fatigue, or component separation, which can lead to machine damage or unsafe operating conditions.
