Loose or damaged screws... Don't you hate that? There are ways to prevent it!
By inserting a flat washer between the screw and the workpiece, the contact area is expanded, reducing the surface pressure on the target material while maintaining a certain fastening force. This helps prevent loosening of the screw, damage to the fastening surface, and stabilizes the seating surface. A resin washer is a washer (or shim) made from resin, also referred to as a plastic washer or resin shim. 【Features】 Resin washers are excellent in insulation and chemical resistance, and unlike metals, they do not rust. They are used for purposes such as weight reduction, chemical resistance, and insulation. 【Product Lineup】 - Flat Washers ○ Delrin Washer (Polyacetal) ○ Black Delrin Washer ○ PTFE Washer (also available in thin type) ○ Nylon Washer (6 Nylon) ○ Black Nylon Washer (6 Nylon) ○ Nylon Washer (66 Nylon) - Rosette Washers ○ Delrin Rosette Washer - Set Washers ○ PEEK Set Washer ○ PTFE Set Washer There are many other types available. *For more details, please contact us or download the catalog.
