Mighty Mule FM600 Parts - H101P Hardware BAG for FM500 Operators
The H101P is a factory-style hardware bag used with select Mighty Mule swing gate operator arms. It supplies the small mounting and service hardware needed around the opener arm, brackets, and related pivot points when the original hardware has been lost, damaged, or removed during repair.
This type of kit is often needed after a gate opener has been taken off the gate for arm replacement, bracket repair, hinge work, or post adjustment. Missing washers, clips, spacers, and fasteners can allow the arm to bind, shift, or wear the mounting points faster than normal.
Because Mighty Mule has used several arm generations and mounting arrangements, the H101P should be matched to the operator model and the original installation diagram. It should not be treated as a universal hardware kit for every Mighty Mule or GTO gate opener.

Technician Note
Do not substitute random hardware in high-load arm pivot areas. Incorrect bolt length, missing spacers, or loose fasteners can change arm geometry and cause premature wear or unsafe gate movement.
Before Ordering
- Confirm the operator model before ordering.
- Compare the needed hardware to the original Mighty Mule parts diagram.
- Check whether you need H101P hardware, HB100 brackets, or a complete replacement arm instead.
- Inspect the gate brackets and post brackets for bending or elongated holes.
- Replace damaged fasteners rather than reusing worn or corroded hardware.
Professional Advisory
Gate arms carry moving loads. If the gate is sagging, binding, or moving out of alignment, correct the gate hardware problem before installing new operator hardware.
Product Questions and Answers
Is H101P a complete replacement arm?
No. H101P is a hardware bag kit. It does not replace the opener arm, motor, control board, or mounting brackets.
Which Mighty Mule models commonly use H101P?
It is commonly listed for FM250, FM350, FM352, FM500, FM502, and FM600 applications, but the parts diagram should be checked.
Can I use regular hardware-store bolts instead?
It is better to use the correct hardware kit because pivot hardware, spacers, washers, and clips must match the operator design.
Is H101P the same as HB100?
No. H101P is a hardware bag, while HB100 is a hardware bracket set used for mounting support on select operators.
When should this kit be replaced?
Replace or use this kit when original hardware is missing, damaged, corroded, or no longer fits tightly at the arm mounting points.
