The Multiquip 1659725PLTC is a genuine OEM Lock Nut Nylon 5/8-11 DA91 designed for the DA91. As a direct OEM replacement, it meets the exact thread specification and nylon insert grade required for proper fastening on the DA91. Sourced from Multiquip's authorized parts network, this nut delivers the correct clamp load and vibration resistance your application demands. Confirm your model code against DA91 to ensure the right fit before ordering.
Key Features
- Nylon Insert Locking Performance — The integrated nylon collar grips threads under vibration, preventing loosening during operation without damaging the mating fastener.
- Correct Thread Specification — Cut to 5/8-11 UNC thread, this nut threads directly onto existing hardware on the DA91 with no chasing or reworking of fastener positions required.
- Genuine OEM Quality — Manufactured to Multiquip's material and dimensional standards, ensuring consistent torque retention and load-bearing capacity specific to DA91 assembly requirements.
- Confirmed DA91 Fitment — Validated for use on the DA91, eliminating guesswork when sourcing a replacement fastener for this machine.
- Maintains Structural Integrity — A failed or missing lock nut can lead to loosened assemblies, misalignment, and accelerated wear on adjacent components; replacing with the correct OEM part restores secure connection.
A nylon insert lock nut is a prevailing torque fastener that uses a deformable nylon collar at the top of the nut to grip the bolt threads and resist loosening caused by vibration, shock loads, or thermal cycling. Unlike standard hex nuts, the nylon element creates friction even when the joint experiences movement, keeping critical assemblies clamped securely over time. When a lock nut wears out, strips, or goes missing, fastener joints can back off under load, leading to loose components, accelerated wear on mating parts, and potential structural failure of the assembly it secures.
