glasses screws Manufacturers

With the development of electronic products, people spend a lot of time in front of mobile phones and computers, and their eyesight has been affected. Glasses have become a very important part of our lives.  When the frame comes loose, you may notice the small screws in the glasses.  As used on the workpiece that often swings, glass screws not only need to be fitted with glasses, but also need to have an anti-loosening effect.  
Glass screws are generally used for the position of the connection between the glasses frame and the glasses frame.  And often swing the glass frame around, the strength of the microscrews will not be enough, and it is easy to break. If the manufacturers choose the wrong material, then it is easy to cause the slide of the glasses screws, so when we choose the glasses screws, in general, we should choose carbon steel and a hard material.
Glasses screws are very small and precise. For most glasses screws, the commonly used specifications are 1*3,1*6,1.4*1.8, etc. Stainless steel and carbon steel are commonly used.  If your glasses are loose, it is because this small screw is not tightened; as long as it is tightened, the glasses will not loosen. Usually, the glasses' screws are cross groove type; of course, there are also slotted.  With the rapid development, the application of glasses screw cross recessed is more and more common, because the glasses screw is very small and precision, relative to the slotted groove, the ability of the cross groove to resist damage under the same torque is greatly enhanced, if it is to use a new machine to assemble glasses, most of the screws are cross drive.  
As a powerful glasses screw factory, we can customize according to customer needs.  For 20 years, we have been committed to creating high-quality small screws, improving the quality of products, and combining with the use of products to customize the production of suitable fastener solutions.
Focused on precision screw manufacturing and customized fastener solutions.

Industry Knowledge

Material Selection and Mechanical Strength

Glasses screws are commonly manufactured from stainless steel, titanium, or specialized alloys to ensure long-term durability, corrosion resistance, and light weight. Precision control over material composition is essential, especially for screws with diameters as small as 0.6mm, to prevent deformation and ensure consistent performance during repeated adjustments.

The mechanical properties must balance strength with flexibility, preventing frame distortion while securing lenses and temple hinges effectively.

Threading and Micro-Precision Techniques

Micro-threading techniques are vital for eyeglass screws, where precision threads provide secure fastening without loosening under small vibrations or repeated wear. CNC machining and thread rolling are employed to produce uniform threads for optimal fit and torque control.

  • Consistent thread geometry minimizes the risk of stripping during lens or hinge assembly.
  • Precision threading ensures secure attachment while allowing controlled adjustments by end-users.
  • Micro-precision screws reduce stress on delicate frame materials, especially in lightweight titanium or acetate frames.

Surface Treatment and Corrosion Resistance

Glasses screws often undergo passivation, polishing, or plating to enhance corrosion resistance and reduce friction during assembly. These treatments are critical for frames exposed to sweat, humidity, and frequent handling.

High-quality surface finishing preserves the visual appeal of visible screws and prevents micro-wear that could affect long-term stability of lenses and hinges.

Property Stainless Steel Titanium Special Alloy
Weight Moderate Light Varies
Corrosion Resistance High Excellent Very High
Strength Good High Moderate to High
Finish Options Polished, Passivated Anodized, Polished Custom Coatings

Applications and Practical Considerations

Glasses screws secure frame temples, nose pads, and lens rims. The precision of screws is crucial to maintaining proper alignment and function, ensuring user comfort and frame integrity.

Using high-precision screws with consistent threading and surface treatment allows for reliable assembly, easier repairs, and longer product lifespan, particularly in high-end or frequently adjusted frames.
