Key Features
- Exact OEM Thread Specification — Manufactured to the precise 1/4-20 thread pitch and 4-3/4 inch length called out in the original assembly, ensuring correct torque and clamping load.
- Genuine OEM Part — Supplied as an authentic Multiquip component, so material grade and dimensional tolerances match what the machine was built with.
- Direct Fitment for ST30 and ST60 — Confirmed compatibility with Multiquip ST30 and ST60 swing-tube concrete pumps; drops into the correct position without modification.
- Hex Socket Drive — Allen head profile allows access and torque application in tight or recessed mounting locations common on concrete pump assemblies.
- Structural Integrity at Every Service Interval — Using the correct fastener length and grade prevents joint loosening, component shift, or premature wear in the assemblies it secures.
A fastener like the EM25598 Allen Head Bolt plays a foundational role in holding critical components of the concrete pump assembly in precise alignment. An incorrect bolt length or thread pitch can result in improper clamping force, which leads to joint movement, accelerated wear on mating surfaces, or component failure under operating pressure. Using the correct OEM-specified bolt ensures that every fastened joint on the ST30 or ST60 maintains its integrity through the demands of continuous concrete pumping work.
