The Multiquip EM492263 is a genuine OEM Allen Screw 3/8-16 x 3/4 designed for a range of Multiquip concrete pumps and vibratory walk-behind rollers. This fastener is a direct factory replacement sourced from Multiquip, ensuring correct thread spec, head geometry, and material grade for the original application. Compatible equipment includes the C30HDNI, C30HDN, and LS300 concrete pump series, as well as the V304EH, V304ER, and V304EY walk-behind vibratory rollers. Sourcing the correct OEM fastener is critical — an improperly sized or graded screw can compromise assembly integrity and lead to component loosening under sustained vibration or load.
Key Features
- Genuine OEM Grade Fastener — Manufactured to Multiquip's exact thread pitch (3/8-16) and length (3/4") specifications, ensuring full engagement and correct clamping force in the original mounting configuration.
- Hex Socket Drive — Allen (hex socket) head design allows precise torque application in tight or recessed mounting locations common on concrete pump and roller assemblies.
- Broad Fitment Across Two Machine Families — Confirmed for the C30HDNI, C30HDN, LS300, LS300GK concrete pumps and V304EH, V304ER, V304EY walk-behind vibratory rollers.
- Correct Grip Length Matters — The 3/4" body length is sized for specific stack thicknesses on these assemblies; substituting a longer or shorter fastener can cause binding, under-clamping, or thread strip-out.
- Genuine OEM Part Number — EM492263 is the factory-assigned Multiquip part number, eliminating guesswork when cross-referencing your service manual or parts diagram.
An Allen screw — also called a socket head cap screw — is a threaded fastener driven by a hex key inserted into the recessed socket on its head. On concrete pumps and vibratory rollers, these screws are used to secure covers, brackets, and structural components where a standard bolt head would interfere with adjacent parts or housings. The 3/8-16 thread designation refers to a 3/8-inch nominal diameter with 16 threads per inch, a common heavy-duty fastener size suited to the mechanical loads and vibration cycles these machines generate. A worn, stripped, or incorrect-grade screw in these positions can allow components to shift during operation, leading to misalignment, accelerated wear, or safety hazards on the worksite.
