Mighty Mule FM352 Parts - H101P Hardware BAG
The H101P hardware bag is a replacement fastener and small-hardware kit used with select Mighty Mule FM series swing gate operators. On a FM352 parts page, this kit is typically ordered when the original bolts, clevis hardware, clips, spacers, or mounting fasteners are missing, worn, corroded, or were not saved during a gate repair. These small parts are easy to overlook, but they are important because the actuator arm needs tight, properly supported pivot points to operate smoothly. A loose or improvised fastener setup can allow the arm to shift under load, which can lead to noisy operation, inconsistent travel, bracket wear, or damage to the control board from repeated obstruction events. This replacement hardware bag is best matched by the operator model and the original exploded parts diagram.

Technician Note
Before installing new small hardware, check the brackets and pivot holes. New pins or bolts will not correct a stretched bracket hole, sagging gate, or operator arm that is being forced out of alignment.
Before Ordering Checklist
- Confirm the operator model and parts diagram callout.
- Confirm you need the hardware bag rather than the bracket set.
- Inspect bracket holes for elongation or cracking.
- Replace missing clips or retainers rather than reusing loose hardware.
- For dual systems, confirm whether one or both actuator arms need hardware.
Important Ordering Warnings
- H101P and HB100 are different items.
- Do not use generic hardware if it changes the pivot fit, clearance, or strength of the opener mounting assembly.
Professional Advisory
If the gate moves unevenly, drags, or binds after hardware replacement, stop using the operator until the gate and mounting geometry are corrected by a qualified technician.
Product Questions and Answers
What is included with H101P?
H101P is sold as a hardware bag or kit for select FM series operators. Exact contents can vary by current packaging, so compare the kit to the missing hardware shown in the parts diagram.
Does H101P replace the HB100 bracket set?
No. H101P is the small-hardware bag, while HB100 is a bracket set. Many repairs use both types of parts, but they are not the same item.
Which Mighty Mule models commonly use H101P?
H101P is commonly listed for FM250, FM350, FM352, FM500, FM502, and FM600 operators, with FM362-D use depending on the matching parts-page reference.
Can I substitute hardware from a local hardware store?
Use the correct size, grade, and style of hardware. Substituting the wrong bolt, clip, or pivot fastener can create play in the arm and cause premature wear.
Why did my mounting hardware come loose?
Common causes include gate sag, poor bracket geometry, worn pivot holes, vibration, missing lock hardware, or the gate repeatedly hitting a hard stop.
