Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original thread and torque specifications for the 5/8-11 thread pitch, ensuring consistent clamping force and holding strength.
- Nylon Insert Locking Mechanism — The integrated nylon collar resists loosening under vibration and load cycles, maintaining joint integrity over repeated use.
- Direct Replacement for MQS-185 — Engineered specifically for the MQS-185, this nut installs directly in place of the original with no rework or modification to mating hardware.
- Correct Thread Engagement — The 5/8-11 UNC thread form ensures full, clean engagement with corresponding fastener hardware, preventing cross-threading or premature wear.
- Fastener Integrity Matters — A worn, stripped, or incorrect stop nut can compromise the security of critical assemblies; using the OEM-specified part maintains the structural reliability of the connection point.
A nylon stop nut — also called a nyloc nut — uses a nylon insert collar at the top of the nut that deforms slightly around the bolt threads when tightened, creating a locking friction that prevents the nut from backing off due to vibration or dynamic loads. This is especially important on construction equipment where constant movement and vibration can work standard fasteners loose over time. When a stop nut loses its locking ability — due to wear, damage, or reuse past its service life — fastener connections can loosen unexpectedly, potentially affecting the safety and function of the assembly it secures.
