The Multiquip 26323 Hex Jam Nut 5/8-18 is a genuine OEM fastener designed for Whiteman ride-on roller screed models WRS5200DFPU, WRS5200, and WRSPUDF. As a direct OEM replacement, part 26323 meets the same dimensional and material standards as the original hardware installed at the factory. Sourced directly through authorized Multiquip supply channels, this nut ensures a correct, secure fit in the assemblies where it is specified. DHS Equipment stocks this part to keep your roller screed back in service without compromise.
Key Features
- Genuine OEM Hardware Grade — Manufactured to the exact thread specification (5/8-18 UNF) and material hardness required for secure fastening in roller screed assemblies.
- Jam Nut Profile for Tight Spaces — The low-profile hex jam nut design allows it to lock against an adjoining nut or component where clearance is limited, threading on without modification.
- Confirmed Fitment — Verified for Whiteman ride-on roller screed models WRS5200DFPU, WRS5200, and WRSPUDF; use part number 26323 to confirm compatibility before ordering.
- Prevents Fastener Loosening Under Vibration — Roller screeds operate under continuous engine and eccentric vibration; a correctly specified jam nut resists backing off and maintains clamping force throughout a pour.
- Direct OEM Source — Supplied as a genuine Multiquip component, so thread engagement, hex dimensions, and finish match the original hardware exactly.
A hex jam nut is a thin, low-profile nut threaded onto a bolt or stud and tightened against a standard nut or mating surface to act as a locking fastener. By bearing against the adjacent nut under load, it resists rotation caused by vibration or dynamic forces — a critical function on equipment like a ride-on roller screed where engines and eccentric shafts generate constant movement. When a jam nut is missing, stripped, or under-torqued, the primary fastener can work loose, leading to misalignment of components, accelerated wear on adjacent parts, or a loss of structural integrity in the assembly it secures.
