In this video, you will learn about different screws used to join temples or arms of glasses with the front part of the frame. Screws come in various sizes and types. These screws are usually very small, ranging from 1.0mm to 2.5mm in length, with fine threads to ensure a secure fit.
The screws are made of metal & are designed to fit into tiny holes in the frame to secure the hinges or hold the lenses in place.
