The Multiquip EMBK227 is a genuine OEM Bolt, Allen Head, 1/2 x 2 1/4 SHCS designed for LS-series and Mayco hydraulic-driven concrete pumps, including the LS60TD, LS600P, LS500, LS600, LS400, LS40D, LS40TD, and LS50TD. As a genuine OEM component, EMBK227 is manufactured to the exact material grade, thread pitch, and dimensional tolerances specified for these machines — ensuring a proper fit in the original fastener location without guesswork. Sourcing the correct hardware is critical on concrete pump assemblies, where fastener integrity directly affects structural and hydraulic system reliability. DHS Equipment stocks this part ready to ship so you can get your pump back on the job without delay.
Key Features
- Correct-Grade Fastener Material — Manufactured to the OEM-specified alloy and hardness rating for socket head cap screw applications on hydraulic concrete pump assemblies.
- Exact Thread and Dimensional Match — 1/2 x 2 1/4 SHCS profile installs directly into the original threaded bore using a standard 3/8-inch hex key, with no thread chasing or modification needed.
- Broad LS-Series Compatibility — Confirmed fitment across LS60TD, LS600P, LS500, LS600, LS400, LS40D, LS40TD, and LS50TD Mayco concrete pump models.
- Structural Integrity Under Load — A correctly torqued SHCS fastener maintains clamping force through vibration and hydraulic pressure cycles; a worn, stripped, or incorrect bolt risks joint loosening and potential fluid or mechanical failure.
- Genuine OEM Part — Supplied as an authorized Multiquip OEM replacement, carrying the same part number used in the original build documentation for these pump models.
A socket head cap screw (SHCS) is a high-strength fastener driven by an internal hex socket, allowing it to be tightened in recessed or tight-clearance locations where a standard hex bolt head would not fit. On hydraulic concrete pumps like the LS-series Mayco units, these bolts are commonly used to secure housings, mounting plates, and structural covers that must withstand continuous vibration and operational stress. When a fastener is missing, under-torqued, or substituted with an incorrect grade, joint integrity is compromised — potentially leading to loosening, leaks, or component damage during pumping operations.
