Key Features
- Grade 2 Fastener Integrity — Meets G2 tensile and hardness specifications, providing the correct clamping force for structural mixer connections.
- Correct Thread Form — Cut to 1/4" NC (National Coarse) thread standard, ensuring full thread engagement with existing mixer hardware without re-tapping or chasing threads.
- Round Head Profile — Low-profile round head seats flush against mating surfaces on the mixer assembly, matching the original installation geometry.
- Broad MQ Mixer Compatibility — Fits MC12PH, MC64P/S, MC94P/S, MC64SK, MC64PK, MC94SK, and MC94PK Multiquip concrete mixer models.
- Genuine OEM Part — Supplied as an authentic Multiquip replacement, so thread pitch, length, and head dimensions match the original bolt exactly as built.
A round head bolt serves as a structural fastener that clamps and secures key components within the concrete mixer assembly, such as drum hardware, guard panels, or drive components. When a fastener stretches, strips, or shears — common occurrences in high-vibration mixing equipment — the connected component can loosen or shift, leading to accelerated wear, misalignment, or unsafe operation. Using the correct grade and thread specification matters because an undersized or lower-grade substitute may not maintain the clamping load the assembly requires under continuous drum rotation and load cycling.
