Lippert Components Part No. 116597 Above-Floor Slide-Out Lippert 116597 Manual Nut -- 0.390" I.D., 5/8" Hex Drive x 1-1/4"

A direct OEM replacement hex nut for Lippert above-floor slide-out systems. When your slide-out mechanism shows wear or stripped hardware, this is the specific nut that restores proper function without guesswork. Order by Lippert part number 116597 and get the right piece the first time.

Purpose-Built for Lippert Above-Floor Slide-Out Systems

Lippert above-floor slide-out systems use a rack-and-pinion or threaded rod drive mechanism where hardware tolerances are tight. The manual nut (part 116597) sits on the drive assembly and is subject to repeated mechanical stress every time the slide extends or retracts. Over time, or after a manual override procedure, this nut can wear, strip, or become damaged and needs replacement.

This is a genuine Lippert Components part, manufactured to the same spec as the original. Using an off-spec substitute can cause binding, uneven slide travel, or accelerated wear on surrounding components -- so matching the part number matters here.

Correct Inner Diameter

0.390" I.D. matches the drive shaft or rod diameter used in Lippert above-floor slide assemblies.

5/8" Hex Drive

Accepts a standard 5/8" socket or wrench for installation and for manual override operation in the field.

1-1/4" Drive Length

The 1-1/4" body length provides adequate thread engagement for secure retention in the slide mechanism.

Genuine Lippert Part

OEM-sourced replacement ensures dimensional accuracy and compatibility with existing Lippert slide hardware.

Where This Nut Is Used

Lippert above-floor slide-out systems route the slide room over the main floor deck. The drive components -- including this nut -- are typically accessible from inside the RV by removing trim panels or an access cover near the slide mechanism. The manual nut specifically allows technicians or owners to manually crank the slide in or out using a drill or socket wrench when 12V power is unavailable or the motor has failed.

Manual Override Use: The 5/8" hex on this nut is the engagement point for manual slide operation. Keep a 5/8" socket and breaker bar or cordless drill in your RV toolkit so you can move the slide even if the motor fails on the road.

When to Replace This Part

  • Visible rounding or stripping of the hex flats (wrench slips during manual operation)
  • Nut is cracked or shows stress fractures after a mechanical override event
  • Slide-out has unusual play or fails to hold position -- worn nut threads can contribute
  • Completing a full slide mechanism rebuild or servicing worn drive components
  • Replacement after a failed manual override attempt stripped the original nut
Verify Your Slide System: Lippert manufactures several slide-out architectures (above-floor, through-frame, Schwintek in-wall, etc.). Part 116597 is specific to the above-floor system. Check your RV owner's manual or the Lippert label on the slide motor/gearbox to confirm you have an above-floor system before ordering.

Installation Notes

Access to the slide drive assembly varies by RV floor plan and wall construction. In most above-floor installations, the drive shaft runs along the floor near the slide opening. The nut is typically retained by torquing to specification against the drive component -- refer to Lippert's slide service documentation for the correct torque value for your specific assembly year and model.

Service Tip: When replacing this nut, inspect the adjacent drive shaft threads and surrounding hardware for wear at the same time. Replacing a single worn component while leaving damaged mating parts accelerates failure of the new nut.
Weight Note: This part ships at approximately 2 lbs. The weight is largely packaging -- the nut itself is a compact piece of hardware. Confirm the part number matches your application before installation.

Important Information
  • This part is designed for Lippert above-floor slide-out systems only -- it is not a universal fit for all Lippert slide types. Confirm your system type before ordering.
  • Do not substitute an off-size nut. The 0.390" I.D. and 5/8" hex must match your drive shaft exactly to avoid binding or component damage.
  • Inspect the mating drive shaft threads before installation. Installing a new nut on a damaged shaft will accelerate wear and repeat failure.
  • If using this nut as part of a manual override procedure, operate the slide slowly and evenly to avoid racking the room off its track.
  • This listing is for the nut only. No additional slide hardware, motor components, or installation hardware are included.
