The Multiquip 505718 is a genuine OEM Hex Head Bolt designed for the LS300GK hydraulic concrete pump, WBH-16 and WBH-21 series Whiteman hydraulic power buggies, and the WTB-16 track buggy. As an authentic Multiquip OEM component, this bolt is manufactured to the exact dimensional and material specifications required for proper assembly and secure fastening across these machine families. Cross-reference your model code before ordering — 505718 is confirmed to fit the WBH-16, WBH-16E, WBH-16EAWD, WBH-16EAWDF, WBH-16EF, WBH-16F, WBH-21EF, WBH-21EFP, WBH21EPA, WTB-16, and LS300GK. Sourced directly from Multiquip, this is the correct part for scheduled maintenance, field repair, or a full reassembly.
Key Features
- Genuine OEM Material Specification — Manufactured to Multiquip's exact grade, thread pitch, and head geometry requirements, ensuring correct torque loading and clamping force at every fastener point.
- Direct Drop-In Replacement — Matches the original bolt in thread size, shank length, and hex head dimensions, seating flush without rework or modification to mating hardware.
- Broad Fitment Across Two Equipment Families — Compatible with LS300GK concrete pumps and the full WBH-16, WBH-21, and WTB-16 Whiteman power buggy lineup, making it a practical stock item for mixed fleets.
- Structural Integrity Where It Counts — A correctly fitted bolt maintains the clamping load that keeps critical assemblies aligned and secure under continuous vibration and load cycling; a worn or mismatched bolt risks joint loosening and component damage.
- OEM Traceability — Part number 505718 is the authoritative Multiquip reference, eliminating guesswork when sourcing through DHS Equipment or submitting service documentation.
A hex head bolt is a fundamental structural fastener used to clamp and secure major assemblies, panels, and mechanical components together on heavy equipment. On machines like power buggies and concrete pumps, fasteners at critical joints are subjected to sustained vibration, dynamic loads, and repeated stress cycles that can cause substandard or incorrect hardware to loosen, strip, or fail prematurely. Using the correct OEM-specified bolt — with the right thread engagement, grade, and head bearing surface — ensures joints stay torqued to specification and structural components remain properly aligned throughout the machine's service life.
