This part is confirmed to fit MC64P, MC64S, MC64SK, MC64PK, MC94P, MC94S, MC94SK, and MC94PK mixer models. Sourced directly from Multiquip, part number 508345 is the correct hardware for maintaining your mixer to original build standards.
Key Features
- Genuine OEM Hardware Grade — Manufactured to Multiquip's original material and thread specification, delivering the correct tensile strength and shear resistance for structural fastening on concrete mixer assemblies.
- Correct Thread Form for Direct Installation — 3/8 NC (National Coarse) thread form installs directly into existing threaded bosses or with standard hardware — no chasing or re-tapping required.
- Broad MC-Series Mixer Fitment — Confirmed for MC64P, MC64S, MC64SK, MC64PK, MC94P, MC94S, MC94SK, and MC94PK Multiquip concrete mixer models.
- Structural Integrity Under Load — Properly torqued fasteners keep mixer components secured during drum rotation and mixing loads; worn or incorrect bolts can cause component loosening, vibration, and accelerated wear on surrounding hardware.
- OEM Part Number Accuracy — Ordering by Multiquip part number 508345 ensures you receive the exact bolt specified for these mixer models, eliminating guesswork when sourcing replacement hardware.
A CS bolt is a carbon steel fastener used to mechanically join structural components within the mixer assembly. In concrete mixer applications, bolts like this one secure key structural and drivetrain-adjacent components that must remain firmly clamped under continuous vibration and rotational load. When a fastener stretches, strips, or fails, it can allow movement between joined parts, leading to accelerated wear, misalignment, or component damage that extends well beyond the bolt itself.
