The Multiquip 492366 is a genuine OEM HHC Screw 5/16-18 x 1-1/2 designed for a broad range of Multiquip and Whiteman equipment including WTB-16, WBH-16, WBH-21, WM120, LS40, LS50, LS60, LS400, LS500, and LS600 series machines. As an authorized Multiquip OEM part, 492366 is manufactured to the exact dimensions and thread specification required for correct assembly and torque retention. Sourced directly through DHS Equipment, this fastener delivers the fit and holding strength the original design depends on. Confirm your model against the fitment list to ensure this is the correct screw for your application.
Key Features
- Exact Thread Specification — 5/16-18 UNC thread form and 1-1/2 in. length match the original fastener spec, ensuring proper engagement depth and clamp load across all listed assemblies.
- Genuine OEM Part — Sourced directly from Multiquip, this screw meets the material grade and dimensional tolerances set during original equipment design — no substitution guesswork.
- Broad Equipment Compatibility — Fits WTB-16 track buggies, WBH-16 and WBH-21 hydraulic buggies, WM120 Whiteman mixers, EM120 Essick mixers, and LS40/LS50/LS60/LS400/LS500/LS600 concrete pumps.
- Structural Holding Integrity — A correctly spec'd hex head cap screw maintains joint integrity under the vibration and load cycles that power buggies, mixers, and concrete pumps generate during operation.
- Drop-In Replacement — Hex head cap screw format installs with standard 1/2 in. wrench or socket, requiring no special tooling or hardware modifications to the mating components.
A hex head cap screw (HHC) is a fully threaded or partially threaded fastener with a six-sided head designed to be driven by a wrench or socket. It serves as a primary structural fastener in equipment assemblies, clamping components together under a specified torque to resist loosening from vibration, dynamic load, and thermal cycling. When a screw of the wrong thread pitch, length, or grade is used — or when an original fastener is stripped, corroded, or missing — the joint loses clamping force, which can lead to component movement, accelerated wear on mating surfaces, or structural failure of the assembly. Using the correct OEM-specified fastener like the Multiquip 492366 ensures the joint performs exactly as engineered.
