The Multiquip 492401 is a genuine OEM 1/2 in. Dia. x 4 in. NC Grade 5 Bolt designed for WTB-16, WBH-16, WBH-21, LS series, and MQ600TD80 power buggies, concrete pumps, and trash pumps. As a factory-sourced component, it meets the original engineering specifications for thread pitch, diameter, and tensile strength used on these machines at the time of manufacture. Verified fitment includes WTB-16PD, WBH-16EAWD, WBH-16F, WBH21EPA, LS400, LS500, LS600, LS40TD, LS60TD, MQ600TD80-TLRP, and MQ600TD80-TLRB. When you need a structural fastener you can count on, sourcing the correct OEM grade and length matters.
Key Features
- Grade 5 Tensile Strength — Medium-carbon steel construction meets SAE Grade 5 standards, providing the clamping force and shear resistance required in structural and drivetrain applications on power buggies and pumps.
- Correct Thread Specification — National Coarse (NC) thread pattern matches the original fastener spec, threading directly into existing hardware without re-tapping or modification.
- Exact OEM Dimensions — At 1/2 in. diameter and 4 in. length, this bolt replicates the precise geometry of the factory-installed fastener for a flush, torque-ready installation.
- Broad Fitment Across Multiquip Families — Compatible with WTB-16, WBH-16, WBH-21, LS400, LS500, LS600, LS40TD, LS60TD, MQ600TD80-TLRP, and MQ600TD80-TLRB machines.
- Genuine OEM Sourcing — Supplied directly through the Multiquip parts network, ensuring you receive the same fastener grade and specification as the original equipment build.
- Structural Integrity Where It Counts — Using the correct grade and length fastener prevents joint loosening, fatigue cracking, and hardware failure under the vibration and load cycles these machines generate during operation.
A Grade 5 hex bolt is a structural fastener used to clamp, align, and secure major assemblies on heavy equipment — including frames, hoppers, drive components, and pump housings. The grade designation indicates the bolt's tensile strength and hardness, which determine how much clamping force it can safely maintain under load and vibration. Using an undersized or incorrect-grade fastener in these positions can result in joint loosening, hardware fatigue, or component separation during operation — making fastener grade and length selection a critical part of any service or repair.
