The Multiquip 50956 is a genuine OEM Bolt 3/8 NC x 5/8 G5 designed for P33/24 HHMR-BD roller equipment and Mayco hydraulic-driven concrete pump models including the LS400, LS500, LS600, LS60TD, LS40D, LS40TD, and LS50TD. As a factory-sourced fastener, it meets the original torque and grade specifications required by Multiquip-engineered assemblies across these equipment families. Sourcing the correct grade-rated bolt matters — using an undersized or off-grade substitute in a structural or mechanical joint can compromise the integrity of the connection and lead to premature failure. DHS Equipment supplies this part direct, so you can be confident you are getting the right specification every time.
Key Features
- Grade 5 Rated Fastener: — Engineered to the SAE Grade 5 tensile and shear strength standard, delivering the clamping force these assemblies demand without risk of stretch or yield under operating loads.
- Correct Thread Form and Length: — 3/8 NC (coarse) thread profile at 5/8 inch length drops directly into existing tapped holes and mating hardware with no chasing or modification to the receiving threads.
- Broad Fitment Across Two Equipment Families: — Confirmed fit for the P33/24 HHMR-BD roller and Mayco hydraulic concrete pump models LS40D, LS40TD, LS50TD, LS60TD, LS400, LS500, and LS600.
- Genuine OEM Sourced: — Supplied as a factory Multiquip part, matching the exact material grade, thread pitch, and head dimensions specified in the original engineering documentation for these machines.
- Structural Joint Integrity: — A correctly graded bolt in a concrete pump or roller assembly maintains proper preload across bolted joints, preventing loosening from vibration and keeping critical components securely positioned during operation.
A Grade 5 hex bolt is a structural fastener rated to a minimum tensile strength of 120,000 psi, making it suitable for mechanically loaded joints found in concrete pump frames, drive assemblies, and roller components. The 3/8 NC coarse thread pattern is designed for reliable engagement in standard steel and cast housings, resisting vibration-induced loosening better than fine-thread equivalents in many field applications. When a fastener of the wrong grade or thread specification is installed in these positions, the joint can lose preload, allow component movement, or fail entirely — creating both a mechanical fault and a potential safety concern in load-bearing or hydraulically active assemblies.
