🔧 How to Remove Propeller Screws Without Damaging Them

Most propeller screws are secured with threadlocker (Loctite) from the factory.

Improper removal may cause the hex socket to strip or the screw to break.

Please follow the correct procedure below:

1️⃣ Use the Right Tool (Critical)

• Use a high-quality hex key (correct size, no wear)

• Use a long-handle ratchet wrench (approx. 25 cm / 10 inch)

👉 This ensures stable torque and reduces the risk of slipping

2️⃣ Fully Insert the Tool

• Make sure the hex tool is fully seated in the screw

• No gaps or looseness

👉 Otherwise, it may strip the hex socket

3️⃣ Apply Downward Pressure

• Use one hand to press down firmly on the tool

• Prevent slipping or cam-out

4️⃣ Turn Slowly Counterclockwise (Most Important)

• ❌ Do NOT apply sudden force

• ❌ Do NOT turn quickly

• ✅ Apply slow, steady counterclockwise torque

👉 This helps gradually break the threadlocker bond

5️⃣ If It’s Too Tight → Pre-loosen Technique

• Slightly turn clockwise (tightening direction) first

• Then turn counterclockwise to loosen

👉 This can help break the threadlocker

6️⃣ Optional: Apply Heat (Advanced)

• Use a heat gun (approx. 80–120°C / 176–248°F)

• Warm the screw to soften the threadlocker

⚠️ Be careful:

• Avoid overheating nearby plastic parts or wires

⚠️ Common Mistakes to Avoid

• Using short L-shaped hex keys (insufficient torque, easy to slip)

• Not inserting the tool fully

• Applying sudden force

• Not pressing down → causes slipping

• Using worn or incorrect tools

🔩 Reinstallation Tips

• Apply threadlocker only to the first ~5 mm of the threads

• ❌ Do NOT use excessive threadlocker

• Use medium-strength (blue) Loctite
