DHS Equipment supplies this part direct, so you can order with confidence knowing you are receiving the correct specification for your machine.
Key Features
- Genuine OEM Hardware Grade — Manufactured to Multiquip's specified thread pitch, hardness grade, and dimensional tolerance for a 7/16 hex nut, ensuring correct torque retention under load.
- Drop-In Replacement — Matches the original fastener specification exactly, threading directly onto existing studs and bolts without rework or modification to mating components.
- Broad Equipment Compatibility — Confirmed fitment across AR14H asphalt rollers, LS300G, LS300GK, LS300P, and LS450 concrete pumps, and R2000 / R2000H static ride-on rollers.
- Structural Integrity Under Vibration — A properly torqued hex nut of the correct grade prevents fastener loosening caused by operational vibration, protecting critical joints and assemblies from failure.
- OEM Part Number Accuracy — Ordering by Multiquip part number EM505081 eliminates the guesswork of cross-referencing generic hardware sizes, so the right nut arrives the first time.
A hex nut is a six-sided threaded fastener used to clamp and secure components onto a bolt or stud. While simple in appearance, using the correct grade and thread specification matters — an undersized or incorrect-grade nut can strip threads, fail to hold torque, or work loose under the continuous vibration that rollers and concrete pumps generate during operation. Replacing a worn or damaged nut with the correct OEM-specification part restores the clamping force the original design requires and prevents damage to the surrounding hardware and assemblies it holds together.
