Multiquip EM161 Nylock Nut #10-24

The Multiquip EM161 Nylock Nut #10-24 is a genuine OEM fastener used across a broad range of Multiquip, Whiteman, and Essick equipment families. As an OEM-sourced component, the EM161 meets the same dimensional and torque-retention standards as the hardware originally installed at the factory. This nut is confirmed for use across rammer, plate compactor, ride-on trowel, walk-behind trowel, roller, concrete pump, mixer, saw, generator, screed, and pump model lines — including MTX60HF, MTX70HF, MTX70HDR, MTX80HDR, MVC82VH, MVC82VHW, MVC88VTH, MVH308GH, HTN27K, HTN28K, HHN31V, AR13H, AR14H, LS400, LS500, and many additional series. Stocking the EM161 ensures you have the correct replacement fastener on hand across your Multiquip fleet without sourcing mismatched hardware.

Key Features

• Genuine OEM Locking Fastener — Sourced directly from Multiquip, the EM161 carries the correct thread specification (#10-24 UNC) and nylon insert grade required to hold torque under vibration.
• Nylon Insert Vibration Resistance — The nylon locking collar grips the mating thread and resists self-loosening — critical on high-vibration equipment such as rammers, plate compactors, and trowels.
• Broad Fleet Coverage — A single part number spans rammers (MTX, MTR), plate compactors (MVC, MVH, MVB), ride-on and walk-behind trowels (HTN, HHN, JWN, STX, MD), rollers, pumps, mixers, saws, and generators — simplifying parts inventory across a mixed Multiquip fleet.
• Direct Drop-In Replacement — The EM161 installs the same way as the original hardware, requiring only standard hand tools and no thread chasing or re-tapping in typical service conditions.
• Fastener Integrity for Critical Assemblies — Using the correctly rated nylock nut prevents fastener back-out on guard panels, belt covers, handle assemblies, and structural mounting points where loosening can compromise operator safety.

A nylock nut — also called a nylon-insert lock nut — is a standard hex nut with a nylon collar pressed into the top of the nut. As the nut is threaded onto a bolt or stud, the nylon collar deforms slightly around the thread, creating friction that resists loosening caused by vibration, dynamic loads, or thermal cycling. This makes it the preferred fastener choice on construction equipment where standard nuts would gradually back off during operation. When a nylock nut is worn, cross-threaded, or missing entirely, fastener joints can loosen unexpectedly, leading to misaligned guards, rattling panels, or — on structural connections — potential component separation. Replacing a compromised nut with the correct OEM part restores the intended clamping load and locking performance of the joint.
