Kohler Nut Wing #KOH-12 100 01-S: Replacement Part Breakdown

The Kohler Nut Wing #KOH-12 100 01-S is a replacement part reference that maintenance buyers and shop support teams may encounter when servicing equipment with Kohler components. For a wing nut, the important question is not just the part name. It is whether the thread, material condition, clamping face, and fit match the application you are repairing. If any of those points are uncertain, verify before installation.

This draft keeps the focus on practical identification and support steps. It does not assume compatibility beyond the part reference provided. For equipment-specific use, confirm the machine model, thread match, and assembly requirements against the OEM documentation or an authorized parts source.

Key Takeaways

• Use the exact part reference when ordering or cross-checking: Kohler Nut Wing #KOH-12 100 01-S.
• Do not assume fit from the part name alone. Verify thread, diameter, pitch, and seating style.
• Inspect the mating stud or bolt before replacing the wing nut. A damaged stud will cause repeat failure.
• If the application is on a machine or service panel, check for vibration, heat, corrosion, and hand-tightening requirements.
• When details are unknown, mark them as Unknown (Verify) rather than guessing.

What This Part Reference Tells You

A wing nut is typically used where hand removal or frequent access is needed. The Kohler part reference suggests an OEM-style replacement component, but the reference alone does not confirm the thread size, finish, or material. Those details matter in field service because a wing nut that starts on the thread but does not seat correctly can loosen, gall the stud, or fail under vibration.

If you are tracking down the correct replacement, document the following before you order:

• Equipment model and serial number
• Location of the fastener on the machine
• Visible thread size and pitch, if measurable
• Old part condition: intact, stripped, cracked, corroded, or heat damaged
• Any washer, lock element, or spacer used with the nut

Troubleshooting and Support Checks

Use a simple inspect-verify routine before installing a replacement wing nut.

Check

• Check the removed nut for thread wear, flattening, cracks, and corrosion.
• Check the stud or bolt for damaged crests, mushrooming, or cross-thread marks.
• Check the mating surface for burrs, distortion, or debris that can prevent full seating.
• Check whether the application is hand-tightened only or exposed to repeated vibration.

Inspect

• Inspect the thread start on the replacement part. The first few turns should not show deformation.
• Inspect for any contamination such as paint, rust, or metal chips in the female or male thread.
• Inspect nearby hardware for signs of looseness that could indicate a larger fastener issue.

Verify

• Verify thread match by measuring or test-fitting by hand. Do not force engagement.
• Verify clearance around the wing tips so the nut can be turned without interference.
• Verify the retained assembly still closes, clamps, or secures correctly after tightening.
• Verify that any replacement maintains the same service access and does not interfere with covers or guards.

If the wing nut begins to bind immediately, stop and recheck the thread. Cross-threading can damage both the nut and the stud. If the part spins freely but never tightens, the thread pitch or diameter may not match, or the stud may already be worn beyond serviceable condition.

Replacement Part Breakdown

For service planning, break the replacement decision into four parts:

1. Identification: Confirm the exact part reference on the existing machine record or removed hardware.
2. Fit: Confirm thread size, thread pitch, and required seating style. Unknown (Verify) if not documented.
3. Condition of mating hardware: Replace or repair the stud, bolt, washer, or panel hardware if damaged.
4. Application demands: Consider vibration, temperature, contamination, and frequency of removal.

This is the point where many repair jobs go wrong. A wing nut is often treated as a generic item, but in maintenance work the wrong fastener can create repeat service calls. The cost of verifying fit is lower than repairing a stripped stud or a loose cover.

Product / Parts Section

The provided product reference is:

• Product name: Kohler Nut Wing #KOH-12 100 01-S
• ASIN: B00CSBT27G
• Amazon affiliate shortcode:

  No products found.

No compatibility, dimensions, material grade, or certification details are confirmed in the source data provided here. Treat those details as Unknown (Verify) until checked against the OEM parts documentation or the product listing from the approved source.

Safety Notes

• Lock out and tag out equipment before removing guards, covers, or retained assemblies when required by site procedure.
• Do not substitute a wing nut in a load-bearing or critical retention point unless the application specifically allows it.
• Do not force mismatched threads. Forced installation can damage the fastener and nearby components.
• If corrosion is present, use appropriate eye protection and hand protection when cleaning or removing hardware.

FAQ

Is the Kohler Nut Wing #KOH-12 100 01-S a universal replacement?

No. The part reference alone does not prove universal fit. Verify the thread, size, and application before use.

What should I do if the new wing nut will not start by hand?

Stop and inspect the stud or bolt for damage, contamination, or incorrect thread pitch. If needed, confirm the replacement against the OEM parts record. Do not force it.

Can I reuse the old stud if the wing nut was stripped?

Only if inspection shows the stud is still in serviceable condition. If the threads are flattened, galled, or deformed, replace the stud or related hardware as required.

What details are still unknown?

Material, finish, exact dimensions, and application-specific compatibility are Unknown (Verify) based on the provided source data.
