DHS Equipment stocks Multiquip OEM hardware so you can get your roller back in service without the guesswork.
Key Features
- Genuine OEM Thread Specification — Manufactured to the exact 20mm, 1.5 fine thread pitch spec, ensuring full thread engagement without cross-threading or torque loss at the fastener joint.
- Direct Hardware Replacement — Matches the original jam nut profile and seating dimensions, so it installs in the same position and locks against the mating component just as the factory unit did.
- Broad Roller Compatibility — Confirmed fitment for RW1810, RW3010, RW1504HF (up to S/N 1534188), P33/24 HHMR-BD with blade, and P33/24 FR/FC/FCR roller models.
- Secure Fastener Locking — Jam nuts are critical for preventing loosening under continuous vibration loads; a worn or incorrect jam nut allows the primary fastener to back off, leading to misalignment or component damage.
- Correct Hardware for Vibration-Heavy Equipment — Rollers generate sustained vibration cycles during operation; using the correct thread pitch and profile is essential to maintaining clamp load over the life of the assembly.
A jam nut is a thin, low-profile nut threaded onto a fastener and tightened against a primary nut or component to lock it in place and prevent it from backing off under load. On vibratory roller equipment, where constant oscillation works against threaded fasteners, jam nuts play a key role in keeping critical assemblies secure and properly positioned. When a jam nut is stripped, worn, or has an incorrect thread pitch, it loses its locking function — allowing the primary fastener to loosen gradually, which can lead to play, misalignment, or accelerated wear in the affected assembly.
