Colored SEMS Screw Both Spring Flat Double Washer

Colored SEMS screw is a screw with both spring and flat washer and then colored by electroplating progress. Colored SEMS screw used on where there needs to be lock tight and decoration. Ever Hardware provides custom-made fasteners and customizable packaging.

SEMS screw combines two separate parts into one pre-assembled, low-cost fastener. With washers under the head, SEMS screws are fast, permanent, and easily adaptable to many applications. Plating is a surface covering in which a metal is deposited on a conductive surface. Plating has been done for hundreds of years; it is also critical for modern technology. Plating is used to decorate objects, for corrosion inhibition, to improve solderability, to harden, to improve wearability, to reduce friction, to improve paint adhesion, to alter conductivity, to improve IR reflectivity, for radiation shielding, and for other purposes. Jewelry typically uses plating to give a silver or gold finish. The thin-film deposition has plated objects as small as an atom, therefore plating finds uses in nanotechnology.
There are several plating methods and many variations. In one method, a solid surface is covered with a metal sheet, and then heat and pressure are applied to fuse them (a version of this is Sheffield plate). Other plating techniques include electroplating, vapor deposition under vacuum, and sputter deposition. Recently, plating often refers to using liquids. Metallizing refers to coating metal on non-metallic objects.
