Multiquip 100078 M6 P-1 Nylon Insert Nut

The Multiquip 100078 is a genuine OEM M6 P-1 Nylon Insert Nut designed for LS600P concrete pumps, AR14H asphalt rollers, and WTB-16 and WTB-16PD power buggies. As a direct OEM replacement, this nut is sourced to the exact Multiquip specification, so you can be confident it threads and torques correctly without guesswork. Verify your model code against the fitment list — this nut is confirmed for LS600P, AR14H, WTB-16, and WTB-16PD — and order with confidence knowing you have the right hardware for the job.

Key Features

• Genuine OEM Hardware Grade — Manufactured to Multiquip's exact M6 P-1 thread pitch and nylon insert specification, ensuring the locking insert engages and holds as intended under operating vibration.
• Self-Locking Nylon Insert — The integrated nylon collar grips the mating thread and resists loosening caused by continuous machine vibration, a critical trait in compaction, pumping, and material-handling equipment.
• Direct Replacement Fit — Part number 100078 threads directly onto M6 P-1 fastener assemblies without rework, filing, or re-tapping.
• Broad Cross-Equipment Fitment — Confirmed for use across multiple Multiquip equipment families including LS600P, AR14H, WTB-16, and WTB-16PD.
• Fastener Integrity Under Load — A loose or failed locking nut on high-vibration equipment can allow panels, guards, and structural brackets to shift or detach; replacing worn hardware promptly keeps assemblies secured and torqued to spec.

A nylon insert nut — also called a nyloc nut — is a standard hex nut with a nylon collar bonded into the top of the nut body. When threaded onto a bolt or stud, the nylon collar deforms slightly around the thread form, creating friction that resists back-rotation and loosening. This makes it the preferred locking fastener in applications subject to continuous vibration, such as pump frames, roller chassis, and buggy drive assemblies. When the nylon insert is worn, cracked, or missing, the nut loses its locking property and can back off under load, leading to loose components, misalignment, or hardware loss.
