Key Features
- Genuine OEM Hardware Grade — Manufactured to Multiquip's original M8x20 thread specification, ensuring correct clamping force and torque retention across the fastener joint.
- Direct-Fit Replacement — Matches the original bolt dimensions exactly, threading directly into existing hardware positions without rework or re-tapping.
- Broad Fitment Coverage — Compatible with HHN31V and STX55-series ride-on trowels, TB11E and TB11G power buggies, and QP2TZ trash pumps — a single part number serving multiple machine families.
- Structural Integrity Where It Counts — A loose or incorrect fastener can cause component misalignment or failure under load; the correct OEM bolt maintains the designed clamping relationship between assembled parts.
- Authentic Multiquip Part — Sold as genuine OEM, so you can be confident the metallurgy and thread form match what left the factory — particularly important for fasteners subject to vibration loads on trowels and compaction equipment.
A hex bolt is a fundamental structural fastener that clamps two or more components together by applying tension through its threaded shank when torqued to specification. On equipment such as ride-on power trowels, power buggies, and trash pumps, fasteners like the M8x20 are used throughout the frame, drive assemblies, and ancillary components where precise clamping load is critical to safe operation. When a bolt stretches, strips, or is replaced with an incorrect size, it can cause joint loosening under vibration, component movement, or premature wear of surrounding parts — making like-for-like OEM replacement the safest choice.
