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 life.  When the frame comes loose, you may notice the small screws in the glasses.  As used on the workpiece that often swings, glasses screws not only need to be fitted with glasses, but also need to have anti-loosening effect.  

Glasses screws are very small and precision. 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 that this small screw is not tightened,as long as it is tightened, the glasses will not loose, 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.
