The Multiquip 11578 Nyloc Nut 7/16-20 is a genuine OEM fastener designed for HTH-Series hydrostatic ride-on trowels. Sourced directly from Multiquip, this nut meets the exact thread specification and torque retention standards required for critical fastening points on HTH-Series machines. If you're performing routine maintenance or a more involved repair, using the correct OEM hardware ensures the joint holds as intended and won't back off under vibration. Verify your model against the HTH-Series fitment before ordering to confirm this is the right part for your machine.
Key Features
- Nylon-Insert Locking Thread — The nylon collar grips the bolt threads and resists loosening caused by continuous vibration and cyclical loading on ride-on trowel assemblies.
- Correct 7/16-20 Thread Specification — Fine-thread 7/16-20 sizing matches the OEM fastener spec exactly, so the nut seats and torques correctly without thread damage or misfit.
- Genuine OEM Hardware — Produced to Multiquip's material and dimensional standards, ensuring consistent clamping force and corrosion resistance across the service life of the fastener.
- HTH-Series Fitment Confirmed — Designed specifically for HTH-Series hydrostatic ride-on trowels, eliminating guesswork when sourcing replacement hardware during a repair or rebuild.
- Direct-Replacement Fastener — Installs in place of the original without rework or adaptation, maintaining the integrity of the assembly it secures.
A nyloc nut is a standard hex nut with a nylon insert bonded into the top of the nut body. As the nut is threaded onto a bolt, the nylon collar deforms slightly around the threads, creating friction that prevents the nut from backing off on its own. This makes nyloc nuts particularly well-suited to applications that experience constant vibration — such as the blade, gearbox, and chassis fastening points on a ride-on trowel. When a nyloc nut is reused too many times, the nylon insert wears down and loses its locking ability, allowing fasteners to work loose during operation. Replacing worn nyloc nuts with a fresh OEM part like the Multiquip 11578 restores the locking performance the joint was designed to rely on.
