The Multiquip EM492455 is a genuine OEM Hex Head Bolt 1/2" x 1-1/2" designed for a broad range of Multiquip equipment including MQ600H-series trash pumps, V305EH and V305EK vibratory rollers, WTB-16PD power buggies, and LS40D, LS40TD, and LS50TD concrete pumps. As a genuine OEM fastener, it is manufactured to the exact dimensions and grade specifications called out in Multiquip's original engineering drawings. Using the correct bolt in structural and mechanical connections ensures proper torque retention and keeps critical assemblies seated and secure under working loads.
Key Features
- Genuine OEM Grade Specification — manufactured to the exact tensile strength and thread specification required by Multiquip's original design, not a generic hardware-store substitute.
- Correct 1/2" x 1-1/2" Dimensions — matches the precise diameter, thread pitch, and grip length needed for a direct drop-in installation on all listed applications.
- Broad Cross-Equipment Compatibility — a single part number covers MQ600H-series trash pumps, V305EH/V305EK walk-behind rollers, WTB-16PD power buggies, and LS40D/LS40TD/LS50TD concrete pumps.
- Maintains Clamping Force Under Load — proper fastener grade prevents joint relaxation, bolt stretch, and connection slippage on high-vibration equipment like compaction rollers and concrete pumps.
- Structural Connection Integrity — using an undersized or incorrect-grade bolt in load-bearing joints on pumps, rollers, or buggies can lead to loosening, component misalignment, or hardware failure during operation.
A hex head bolt is a fundamental structural fastener that clamps two or more components together and holds them at a defined preload when torqued to specification. In construction equipment, bolts in this size class are commonly used to secure housings, mounting brackets, guards, and drive components where consistent clamping force is critical to safe and accurate operation. When a bolt is the wrong grade, wrong length, or has been stretched beyond its elastic limit, it can work loose under vibration — leading to component separation, accelerated wear on mating parts, and potential equipment damage.
