The Multiquip 021112140 is a genuine OEM Hex Nyloc Nut M12-1.75 designed for a wide range of Multiquip equipment including rammers, ride-on power trowels, welders, and diesel-powered generators. This fastener is a direct OEM replacement, ensuring the correct thread pitch, material grade, and locking specification for every application it serves. Compatible models include the MTX70HF, MTX70HDR, MTX80HDR, MTX-i60, MTR40HF, MT60H2, MD80, MD105, LD60, LD6, STXDF, DLW300ES, DLW400ESA4, DLW500ESA4, DAW500SA4, DA7000SSA2, and DA7000SSA2GH. Sourcing the correct OEM fastener ensures the connection holds to specification and the nylon locking insert performs as intended across the full service life of the assembly.
Key Features
- Genuine OEM Locking Performance — The nylon insert is engineered to the correct interference specification, delivering consistent vibration resistance under the demanding operating conditions of compaction, finishing, and power generation equipment.
- Correct M12-1.75 Thread Specification — Matches the exact thread pitch used across Multiquip assemblies, threading on cleanly without risk of cross-threading or under-torquing due to dimensional mismatch.
- Broad Cross-Equipment Compatibility — A single verified part number covers rammers (MTX70, MTX80HDR, MTX-i60, MTR40HF, MT60H2), ride-on trowels (MD80, MD105, LD60, LD6, STXDF), welders (DLW and DAW series), and diesel generators (DA7000SSA2 series).
- Maintains Fastener Integrity Under Vibration — The nyloc design prevents the nut from backing off during operation, keeping critical joints tight on equipment that runs under sustained vibration loads.
- OEM Sourcing Through DHS Equipment — Supplied as an authorized Multiquip OEM part, so the part number, grade, and specification match exactly what the machine shipped with.
A hex nyloc nut uses a nylon insert collar at the top of the nut that deforms slightly around the bolt threads when installed, creating friction that resists loosening from vibration and dynamic loading. On equipment like rammers and plate compactors, where constant vibration is inherent to operation, standard hex nuts can gradually back off and compromise the integrity of the fastened joint. The nyloc design eliminates this risk by maintaining clamping force even through extended duty cycles. When a nyloc nut is worn, damaged, or replaced with an incorrect thread pitch, the assembly may loosen in service, leading to structural movement, accelerated wear at the joint, or component failure.
