The Multiquip 505081 is a genuine OEM Hex Nut 7/16 designed for R2000H and AR14H rollers, as well as LS300P, LS300G, and LS300GK concrete pump models. As a factory-sourced fastener, part 505081 is manufactured to the exact thread pitch, grade, and dimensional tolerances required by Multiquip equipment, ensuring a secure, properly torqued connection every time. Verified fitment across multiple Multiquip roller and concrete pump platforms makes this the straightforward choice when sourcing replacement hardware for your equipment.
Key Features
- Genuine OEM Thread Specification — Manufactured to the exact 7/16 thread pitch and grade required by Multiquip, ensuring correct torque load and fastener integrity at the joint.
- Direct Hardware Replacement — Matches the original fastener profile for drop-in installation without reworking mating components or connection points.
- Broad Multiquip Fitment — Compatible with R2000H and AR14H rollers and LS300P, LS300G, and LS300GK concrete pumps, covering multiple equipment families with a single part number.
- Structural Connection Integrity — A correctly rated hex nut maintains clamping force across critical assemblies; an undersized or worn fastener risks loosening under vibration and load, leading to component misalignment or failure.
- Torque-Critical Safety Hardware — On rollers and concrete pumps, fastener failure at key connection points can compromise operator safety and machine stability — using the correct OEM-spec nut is essential.
A hex nut is a threaded fastener that mates with a bolt or stud to clamp components together and maintain a secure, load-bearing connection. In heavy equipment like rollers and concrete pumps, hex nuts are used throughout structural, mechanical, and hydraulic assemblies where consistent clamping force is critical to safe operation. When a hex nut strips, corrodes, or is replaced with an incorrect grade or thread pitch, the joint can loosen under vibration or pressure, potentially leading to component separation or equipment damage.
