The Multiquip 57129 is a genuine OEM Hex Jam Nut 8mm designed for Multiquip roller models including RW1810, RW1504HF (up to S/N ), P33/24 HHMR-BD with Blade, and P33/24 FR/FC/FCR variants. As a factory-sourced fastener, part 57129 matches the original hardware specification to ensure a flush, secure installation with no guesswork. DHS Equipment stocks this genuine Multiquip component so your roller returns to service exactly as the manufacturer intended.
Key Features
- Genuine OEM Hardware Grade — Sourced directly from Multiquip, this 8mm hex jam nut meets the original thread pitch, hardness, and torque rating specified for roller assembly fastening points.
- Drop-In Fastener Fit — Threaded to match the existing hardware on your roller's assembly, allowing straightforward hand-start installation before final torque.
- Broad Roller Compatibility — Confirmed fitment for RW1810, RW1504HF (up to S/N 1534188), P33/24 HHMR-BD with Blade, and P33/24 FR/FC/FCR models.
- Locks Adjustment in Place — The jam-style profile acts as a locking nut against a primary fastener, preventing loosening from vibration during compaction passes.
- Fastener Integrity Under Load — A worn, stripped, or incorrect jam nut allows critical roller components to shift under operating vibration, compromising compaction consistency and accelerating wear on adjacent hardware.
A hex jam nut is a thin-profile locking nut threaded against a primary nut or fastener to prevent it from backing off under vibration or repeated loading cycles. On compaction rollers like the RW and P33/24 series, machine vibration is constant during operation, making proper fastener security essential to keeping adjustable components — such as eccentric shafts, scrapers, and frame-mounted hardware — correctly positioned. When a jam nut is missing, stripped, or the wrong size, the mating fastener can loosen progressively during use, leading to misalignment, accelerated wear on surrounding components, or unexpected downtime in the field.
