Supports and Seats the Screw Head
The cup-shaped recess accommodates the screw head, providing a more stable seating surface after installation and helping reduce head misalignment or direct pressure on the workpiece.
Distributes Fastening Pressure
The larger outside diameter increases the contact area with the workpiece, distributing fastening pressure over a wider area and helping reduce localized indentation or deformation around the mounting hole.
Protects the Workpiece Surface
The CUP WASHER separates the screw head from the workpiece, helping reduce scratches, indentations, and coating damage caused by tightening, removal, or vibration.
Improves Assembly Appearance
The cup-shaped profile helps create a cleaner appearance around the screw installation area and can cover larger mounting holes or exposed edges. It is suitable for equipment, furniture, and decorative components where appearance is important.
Multiple Material Options Available
Metal or plastic materials can be selected according to strength, rust resistance, corrosion resistance, insulation, and appearance requirements, with different surface treatments available as needed.
