Key Features
- OEM-Spec Thread and Geometry — Manufactured to the exact 3/4-10X14 thread specification, ensuring proper engagement, clamping force, and torque retention in concrete pump applications.
- Drop-In Installation — Matches the original bolt pattern and dimensions on C30HD-series pumps, so installation is straightforward without reworking mounting points.
- Broad C30HD-Series Fitment — Compatible with the C30HD, C30HDNI, C30HDNI Precision, C30HDN, C30HDNI Zenith, C30HDG, C30HDZ, and C30HDGA concrete pumps.
- Structural Integrity Under Load — A correctly installed T-bolt maintains critical joint clamping in high-vibration pump environments; a worn or incorrect fastener can lead to loosening, leaks, or component damage.
- Genuine OEM Confidence — Supplied as an authentic Multiquip OEM part, meaning the material grade, thread form, and dimensional tolerances match what left the factory originally.
A T-bolt is a specialized fastener used in concrete pump assemblies to clamp and secure housings, flanges, or wear components under sustained mechanical stress and vibration. Unlike standard hex bolts, T-bolts are designed to seat within a slot or channel, resisting rotation during tightening and maintaining consistent clamping force across the joint. When a T-bolt is worn, stripped, or incorrectly sized, it can allow critical connections to work loose during pump operation, resulting in material leaks, misalignment, or accelerated wear on surrounding components. Using the correct OEM replacement ensures the joint performs as originally engineered.
