Understanding screw sizing is critical. Glasses require a variety of screws depending on their design: hinge screws, nose pad screws, temple screws, and specialized screws for rimless frames. Each type has specific lengths, diameters, and thread patterns, and using the wrong screw can compromise frame integrity and increase customer complaints. Distributors who supply accurately sized screws reduce errors and improve operational efficiency for optical shops.
