🧩 How to Choose the Right Eyeglass Screw Size for Your Frames

When it comes to repairing glasses, one of the most common challenges is finding the correct screw size. Using the wrong screw can strip the hinge, damage the frame, or leave your glasses unstable. Fortunately, with a little guidance and the right tools, choosing the right screw size is simple.

This guide will explain standard eyeglass screw sizes, how to identify the correct one for your frames, and why a SnapitScrew Refill Kit is a must-have for every glasses wearer.

👓 Why Screw Size Matters

Eyeglass screws may look tiny, but using the wrong size can have big consequences:

• Too small: Won’t hold the hinge securely, causing wobbly arms or loose lenses.

• Too large: Can crack the frame or strip the threads.

• Incorrect length: May prevent proper hinge closure or leave the screw sticking out.

Choosing the right size ensures your glasses remain stable, comfortable, and safe to wear.

🧰 Common Eyeglass Screw Sizes

Most eyeglass repair kits, including SnapitScrew, include the following standard screw diameters:

• 1.2 mm – used for smaller hinges or thin rimless frames.

• 1.4 mm – the most popular size, fits most standard metal and plastic frames.

• 1.5 mm – slightly larger, for thicker or specialty frames.

• 1.6 mm – used for some rimless lenses and heavy-duty metal frames.

• 1.7 mm – largest common size, often for oversized frames or designer glasses.

💡 Pro Tip: If in doubt, the 1.4 mm screw is usually a safe choice for most repairs, but always double-check the hinge diameter.

🔍 How to Identify the Correct Screw Size

1. Check Your Frame Type

• Metal frames: Often use 1.2, 1.4, or 1.5 mm screws.

• Plastic frames: Usually 1.4 or 1.5 mm.

• Rimless frames: Smaller screws (1.2 or 1.6 mm) for lens attachment.

2. Measure the Old Screw

If you still have the original screw, measure the diameter and length. SnapitScrew kits include multiple sizes to match almost every need.

3. Use a Refill Kit

The SnapitScrew Refill Kit comes with five sizes: 1.2, 1.4, 1.5, 1.6, and 1.7 mm. This ensures you always have the correct screw on hand without guessing.

🔧 Step-by-Step: Replacing Eyeglass Screws

1. Prepare your work area – use a soft towel to prevent scratches.

2. Identify the screw to replace – hinge, lens, or nose pad.

3. Select the correct size – refer to the chart above or use your SnapitScrew kit.

4. Insert the screw – align the hinge or component, and use the precision screwdriver.

5. Tighten gently – avoid stripping the threads.

6. Snap off the screw tail – for a clean finish if using Snapit screws.

7. Test the glasses – ensure arms open smoothly and lenses are secure.

💡 Tip: Keep a few spare screws from the refill kit for quick repairs — they’re tiny but essential!
