■Features - This is a set washer made of black Duracon. - The set washer functions similarly to a flat washer, but by forming protrusions or tabs in the inner diameter, it engages with the screw to prevent the washer from falling off. - It facilitates tightening work and is particularly effective in tasks that use small screws. - The washer is a thin disc with a hole in the center for passing a screw through. - Compliant with EU-RoHS2 standards.

- Washers are generally used by placing them between the screw and the workpiece when tightening screws, with the purpose of preventing loosening of the screw, protecting the fastening surface from damage, and stabilizing the seating surface. - By inserting a washer between the screw and the workpiece, the contact area is increased, which reduces the surface pressure on the material, maintaining a certain fastening force and preventing loosening of the screw, protecting the fastening surface from damage, and stabilizing the seating surface. - Set washers function similarly to flat washers, but they are designed with protrusions or tabs on the inner diameter to engage with the screw and prevent the washer from falling off. - They facilitate tightening operations and are particularly effective in tasks that use small screws. - To prevent damage to the workpiece, it is common to use the screw head, set washer, and workpiece in that order. - Plastic washers are used for weight reduction, insulation, and chemical resistance, as they are lightweight and do not rust unlike metal washers.
