How to repair loose and falling screws of titanium glasses frames

Titanium glasses are loved by users for their lightness, firmness and low allergy. But even with superior materials, you may still encounter a common problem after long-term wear: loose screws or even falling off. Especially at the connection between the temples and the frame and the nose pads, if not handled properly, it will affect the wearing stability and even cause the lenses to fall off. So, when your titanium glasses frame screws are loose or even fall off, how should you repair them? This article provides you with detailed operation guides and prevention tips.

Why are the screws of titanium glasses easy to loosen?

Although titanium alloys have strong corrosion resistance, titanium glasses are not all titanium structures, and screws and other connectors are usually stainless steel or nickel-plated metal. Common causes of loose screws include:

Repeated opening and closing of temples for a long time, leading to metal fatigue;

Large temperature changes, causing thermal expansion and contraction;

Lubrication or oxidation between threads, reducing friction;

Screws loosen naturally if not tightened regularly.

 

Emergency repair method when the screw is loose

Tighten with a professional eyeglass screwdriver

When you find that the temple is shaking and the screw is floating, immediately use a special small screwdriver (commonly a cross or flat head) to rotate clockwise to tighten the loose part. Note when operating:

Place the frame firmly on a flat surface;

Apply force lightly, not too hard;

Prevent scratching the frame or breaking the thread.

If there is no professional tool, you can temporarily use a fine flat screwdriver instead, but it is not recommended for long-term use.

Apply screw fixing fluid to prevent loosening again

After tightening, you can drip a little screw glue (such as Loctite Blue 242) into the thread to enhance the locking effect. Note:

Clean the oil in the screw hole before use;

After applying, let it stand for 2-3 hours before wearing;

Do not use super glue or 502 to prevent the screw from being unable to be removed.

 

If the screw has fallen off, how to remedy it?

Find the original screw and reinstall it

If the screw is not lost, try to screw it back. First, use tweezers to align the screw hole and insert the screw, then use a screwdriver to slowly screw it in. If assembly is difficult:

You can apply a small amount of solid lubricant to the screw head;

Use a flashlight to illuminate and check if the thread is damaged.

Alternative method when the screw is lost

If the screw is lost, you can go to the eyewear store to replace the original screw. Usually:

M1.2, M1.4 and other micro screws;

The length is 2-4mm;

It is recommended to choose stainless steel to avoid electrochemical corrosion.

⚠️ It is not recommended to assemble non-standard screws at will to avoid damaging the thread.

 

What to do if it cannot be repaired?

If the screw hole is damaged or the thread is slipped, it is recommended to send it to a professional eyewear repair shop for the following treatment:

Replace the nut or temple parts;

Use spring rivets to replace the connection;

Laser welding to repair the titanium frame structure (applicable to broken or aged parts).

Titanium alloy is difficult to process, and ordinary tools or manual work are difficult to handle complex problems.

 

How to prevent titanium eyewear screws from loosening?

Check the tightness of the screws regularly (once a month);

Avoid frequent wearing and removing with one hand to reduce uneven force on the temples;

Prevent storage in high temperature and high humidity environments to delay corrosion;

Use a non-slip and shockproof glasses case for protection, making it safer to carry when going out.
