The Multiquip 101 Hex Bolt 5/16-18X1 1/2 is a genuine OEM fastener designed for C30HD concrete pump equipment. As a direct OEM replacement, this bolt is manufactured to the exact thread pitch, diameter, and length specification required by the machine, ensuring a secure and properly torqued connection every time. Sourced directly through authorized channels, this is the same hardware used in original assembly of C30HD units.
Key Features
- OEM-Grade Fastener Specification — Manufactured to the exact 5/16-18 thread pitch and 1 1/2-inch length called out in the original equipment bill of materials, so torque ratings and clamping force meet design intent.
- Direct Hardware Match — Threads in without modification, matching the original bolt pattern and seat geometry on C30HD assembly points.
- Confirmed C30HD Fitment — Verified for use on Multiquip C30HD concrete pump equipment.
- Structural Integrity Maintained — A correctly spec'd bolt keeps critical assemblies clamped at the proper load; a mismatched or worn fastener can lead to loosening under vibration and pump failure.
- Genuine OEM Part — Carries Multiquip OEM sourcing, giving you confidence that grade, material, and dimensional specs are not approximated.
A hex bolt may be a small component, but in concrete pump applications it carries real structural responsibility — securing housings, guards, brackets, and drive components that are subject to constant vibration and mechanical stress. The 5/16-18 thread designation refers to the bolt's diameter and thread count per inch, while the 1 1/2-inch length determines how much clamping engagement the fastener provides through a given stack of material. Using an incorrect length or thread pitch can result in under-clamping, cross-threading, or fastener backing out during operation — all of which can cause component damage or unplanned downtime on the job.
