The Multiquip 02041023452 Bolt Stud ST-4100 is a genuine OEM fastener designed for the ST-4100 swing tube concrete pump. As a direct factory replacement, this stud delivers the correct thread form, shank diameter, and material grade required to maintain a secure, properly torqued connection in a high-demand pumping application. Sourced directly from Multiquip, part 02041023452 is the exact component specified for ST-4100 service and repair.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and thread specifications, ensuring the stud holds rated clamping load without stretching or backing out under pump vibration.
- Direct-Fit for ST-4100 — Engineered specifically for the ST-4100 swing tube concrete pump; installs in the same position and orientation as the original with no rework to mating hardware.
- ST-4100 Series Compatibility — Confirmed fitment for ST-4100 equipment, eliminating the guesswork that comes with generic fastener substitutions on precision pump assemblies.
- Structural Integrity Under Load — A correctly installed stud keeps critical pump assemblies properly clamped and aligned; a worn, stripped, or incorrect stud can lead to joint movement, leaks, or unexpected disassembly during operation.
- Clean Swap for Scheduled Maintenance — Replacing studs at recommended service intervals preserves thread engagement in the parent casting and extends the service life of surrounding components.
A bolt stud is a headless threaded fastener anchored into a tapped bore on one end, with a free-threaded end that accepts a nut to clamp an adjoining component. On a concrete pump like the ST-4100, studs are commonly used at high-stress joint faces — such as valve housings, wear plates, and access covers — where a through-bolt is not practical. When a stud stretches, strips, or breaks, the joint can no longer be properly torqued, resulting in misalignment, fluid leaks, or component separation that takes the pump out of service. Using the correct OEM replacement stud ensures the thread engagement depth, material strength, and torque capacity match what the original design requires.
