Key Features
- Genuine OEM Hardware Integrity — Produced to the exact thread pitch, diameter, and material grade specified for the ST-2020B concrete pump, ensuring proper torque retention and joint security.
- Direct Bolt-In Replacement — Threads and shoulder dimensions match the original mounting points on the pump assembly, allowing straightforward installation without rework or modification to surrounding components.
- Confirmed ST-2020B and 2020-B1 Fitment — Validated for use on Multiquip ST-2020B and 2020-B1 swing tube concrete pumps, eliminating guesswork when sourcing hardware for these models.
- Structural Clamping Performance — A correctly sized and properly torqued stud bolt maintains consistent clamping force across pump flanges and mounting faces, preventing joint movement that can lead to leaks or component damage under operational pressure.
- Pressure-System Safety Relevance — On a concrete pump, loose or undersized fasteners at high-pressure junctions are a genuine safety concern; using the correct OEM stud bolt helps maintain the structural integrity of pressurized connections.
A stud bolt is a fully threaded fastener used to clamp two mating surfaces together with a nut on one or both ends, providing a strong and repeatable bolted joint. On a concrete pump like the ST-2020B, stud bolts are commonly used at high-load connection points such as flanges, cylinder heads, and pump body interfaces where vibration and pressure demand reliable fastener engagement. When a stud bolt stretches, strips, or breaks, it compromises the clamping load at that joint, which can result in leaks, misalignment, or accelerated wear on surrounding components — making prompt replacement with the correct OEM part essential.
