The Multiquip EMB is a genuine OEM Bolt Allen Head 1/2 x 1-1/4 SHCS designed for hydraulic-driven concrete pump models including the LS40D, LS40TD, LS50TD, LS400, LS500, LS600, LS600P, and LS60TD. As a factory-sourced fastener, EMB meets the exact dimensional and torque specifications required for these Mayco concrete pump assemblies. Sourced directly through Multiquip's OEM supply chain, this bolt delivers the fit and holding strength that critical pump applications demand. DHS Equipment stocks genuine Multiquip parts to help you get the right component the first time.
Key Features
- Socket Head Cap Screw Construction — The hex socket (Allen) drive design allows high-torque installation in tight or recessed mounting locations common on concrete pump assemblies.
- Genuine OEM Fastener Grade — Manufactured to the precise tensile strength and thread specification required by Multiquip for these hydraulic concrete pump models, not a generic hardware substitute.
- Direct-Fit for LS-Series Concrete Pumps — Confirmed fitment across LS40D, LS40TD, LS50TD, LS400, LS500, LS600, LS600P, and LS60TD — install directly without modification.
- Maintains Clamping Integrity — Correct bolt sizing and grade ensures consistent clamping force on pump components, preventing loosening under the vibration and hydraulic pressure loads these machines generate.
- Exact Dimensional Spec — 1/2-inch diameter by 1-1/4-inch length SHCS profile matches the OEM assembly drawing, ensuring proper thread engagement and flush or recessed seating.
A socket head cap screw (SHCS) is a high-strength fastener with a cylindrical head and internal hex drive, used where a standard bolt head would not clear surrounding components or where high clamping loads are required in a compact space. On hydraulic concrete pumps like the LS-series, these bolts are commonly used to secure pump housings, valve blocks, and drive components that must remain firmly fastened under continuous hydraulic pressure and mechanical vibration. Using the correct OEM-specified bolt — right diameter, length, and grade — is essential; an incorrect fastener can back out, strip threads, or fail to maintain the seal and alignment that keep the pump operating safely.
