Lost an Eyglasses Screw? Here's How to Find the Right Size and Replace It in 60 Seconds

Lost an Eyglasses Screw? Here's How to Find the Right Size and Replace It in 60 Seconds

The screw is gone. You heard the tiny ping, watched it bounce once, and now it's vanished into another dimension—probably the same one that claims missing socks and guitar picks.

Here's the good news: you don't need to find it. You don't even need to know what size it was. With the right kit, you can replace any glasses screw in about 60 seconds.

Why Glasses Screws Disappear

Glasses screws are engineered for precision fitting, not for being found after they fall out. At 1.2mm to 1.7mm diameter, they're smaller than grains of rice and nearly invisible against most floor surfaces.

The progressive loosening that precedes a complete screw loss usually goes unnoticed. The screw gradually backs out over weeks or months until it finally drops free. By then, it's been protruding slightly from the hinge and can fall at any moment—often during movement, guaranteeing it lands somewhere impossible to find.

Even if you know roughly where the screw fell, finding it is genuinely challenging. Carpet fibres hide tiny screws completely. Hard floors let them roll under furniture instantly. The shiny metal head might catch light if you're lucky, but often the screw simply vanishes forever.

Forget Searching, Start Replacing

Time spent searching is time without functional glasses. Unless the screw landed on a contrasting surface right in front of you, replacement is faster and more reliable than searching.

The SnapItScrew kit (https://snapitscrew.com/) includes five screw sizes: 1.2mm, 1.4mm, 1.5mm, 1.6mm, and 1.7mm. These sizes cover virtually every pair of glasses manufactured in the past several decades. Your missing screw was almost certainly one of these sizes.

You don't need to identify the exact size before starting. The process works by simple trial: if one size doesn't fit smoothly, try the next. Most people find the right size within one or two attempts.

The Replacement Process

First, identify where the screw belongs. Most glasses have hinge screws connecting each arm to the frame front. Some have additional screws at the bridge or holding rimless lenses in place. Look for the empty hole where your screw came out.

Hold the arm in position against the frame so the screw holes align properly. You might need to support the frame on a flat surface or ask someone to help hold things steady.

Select a SnapItScrew in what you estimate to be the right size. For standard glasses, the medium 1.4mm size is most common. Start there unless your frames are obviously smaller or larger than typical.

Push the SnapItScrew's feeder tab through the hinge hole. The extended tab gives you complete control—no tweezers needed, no fumbling with microscopic parts. If the screw slides through easily with room to spare, try a larger size. If it won't enter the hole at all, try smaller.

Once you find the right fit, use the included screwdriver to tighten. Turn clockwise until snug but not forced. The screw should hold the hinge firmly without stripping or cracking the frame material.

Finally, snap off the feeder tab by bending it with your fingers. It's designed to break cleanly at the screw head, leaving a perfect finish. Done.

What If None of the Sizes Work?

In rare cases, frames use non-standard screw sizes. This is most common with very old glasses, unusual designs, or certain international brands that don't follow typical conventions.

If no SnapItScrew size fits properly, you have several options:

The slightly-too-small approach uses a screw one size smaller than ideal, applying a tiny amount of clear nail polish to the threads before inserting. This adds thickness and helps grip. Not perfect, but functional.

The slightly-too-large approach involves gentle pressure while turning, which might thread a marginally oversized screw in. Be careful—forcing risks cracking the hinge barrel.

Professional help remains an option for frames that genuinely need specialty screws, though this is uncommon.

However, these situations are rare. The five sizes in the SnapItScrew kit (https://snapitscrew.com/) fit the overwhelming majority of glasses ever made.

Preventing Future Losses

Once your glasses are fixed, a few habits prevent repeating the experience:

Check hinge tightness monthly. A gentle wiggle of each arm reveals loosening before it becomes critical. Tighten promptly when you notice any play.

Handle glasses carefully. Use both hands when putting glasses on or taking them off. Store in cases, not loose in bags or pockets.

Keep your SnapItScrew kit (https://snapitscrew.com/) accessible. When you notice the first wobble, fix it immediately rather than waiting for complete failure.

You CAN fix this yourself in 60 seconds. Stop searching and start replacing
