Compatible equipment includes WTB-16, WBH-16, WBH-16E, WBH-16EF, WBH-16F, WBH-16EAWD, WBH-16EAWDF, WBH-21EF, WBH-21EFP, WBH21EPA, WM120SH, WM120PH, EM120S Series, EM120P Series, LS40D, LS40TD, LS50TD, LS60TD, LS400, LS500, and LS600. Ordering by part number EM492366 guarantees you receive the exact fastener specified for your machine.
Key Features
- Genuine OEM Grade Strength — Manufactured to the same tensile and torque specifications as the original fastener, ensuring joints hold under the vibration and load demands of concrete and pump equipment.
- Correct Thread Form and Length — 5/16-18 UNC thread pitch and 1-1/2 inch grip length match the original tapped holes, so the fastener seats fully without bottoming out or under-engaging.
- Broad Equipment Coverage — A single part number covers WTB-16 and WBH-series power buggies, WM120 and EM120 mortar mixers, and LS-series Mayco concrete pumps, simplifying parts stocking across a mixed fleet.
- Structural Integrity Where It Counts — Used in assemblies subject to continuous operational vibration; an incorrect or worn fastener in these positions can lead to loosening, misalignment, or structural failure of connected components.
- Direct OEM Sourcing — Supplied through DHS Equipment as an authorized Multiquip parts distributor, so the fastener you receive matches the EM492366 specification exactly as released by the manufacturer.
A hex head cap screw is a fully threaded or partially threaded fastener with a six-sided head designed to be driven by a wrench or socket, providing high clamping force across bolted joints. In heavy equipment like power buggies, mortar mixers, and concrete pumps, these fasteners secure critical structural and mechanical assemblies that must withstand continuous vibration, torque, and load cycling during operation. When a fastener of the wrong grade, thread pitch, or length is substituted, clamping force is compromised — leading to joint movement, accelerated wear on mating components, and the risk of assembly failure in the field. Using the correct OEM fastener, specified by part number EM492366, preserves the integrity of every joint it secures.
