Loose or stripped mount screws cause vibration and phone wobble. Follow this step-by-step guide to swap them safely using the Quad Lock Replacement Screw Set.
Quick answer
Replace worn or loose screws on your motorcycle mount with the Quad Lock Replacement Screw Set. Match the original screw size and head type, apply a small amount of threadlocker, and tighten to a snug fit without overtightening.
Why screw condition matters on a motorcycle mount
Motorcycle mounts endure constant vibration, weather, and road shock. Over time, screws can loosen, strip, or corrode, leading to phone wobble or even mount failure. Replacing them proactively is cheaper than replacing the whole mount.
When to replace instead of just tightening
If a screw keeps coming loose after tightening, or if the head is stripped or threads are damaged, replacement is necessary. Tightening a damaged screw can further strip the mount's threads, turning a simple fix into a costly repair.
Step-by-step screw replacement
- Identify the worn screws: Inspect all screws on your mount for looseness, stripped heads, or corrosion. Mark the ones that need replacement. Check both the mount base and the phone cradle—vibration can affect both.
- Remove the old screws: Use the correct size screwdriver or hex key to remove the worn screws. If a screw is stripped, use a screw extractor or carefully drill it out. Apply penetrating oil to corroded screws and let it sit before removal to avoid breaking them.
- Match the replacement screw: Compare the old screw to the screws in the Quad Lock Replacement Screw Set. Match the thread size (M4 or M5), length, and head type (socket or button). If the old screw is too damaged to measure, refer to your mount's manual or contact support for the correct size.
- Apply threadlocker: Apply a small drop of medium-strength threadlocker (like blue Loctite) to the threads of the new screw. This prevents loosening from vibration. Avoid getting threadlocker on plastic parts—it can degrade some plastics.
- Install and tighten: Thread the new screw in by hand first to avoid cross-threading, then tighten with the appropriate tool until snug. Do not overtighten. Overtightening can strip threads or crack the mount—stop when you feel firm resistance.
- Test and recheck: After installation, test the mount by gently wiggling the phone cradle. Check all screws after the first ride and periodically thereafter. Recheck screw tightness every few rides, especially after rough terrain.
