Black Screws Nickel Plating Screws For Plastic Nickel Fasteners

Black screws are the screws with black galvanizing or nickel plating or electrophoresis. The screws are much pretty and more smoothly than the normal plating screws. Black screws with plastite thread mostly used on electronics. Ever Hardware provides custom-made fasteners and customizable packaging.

The PLASTITE screw is designed to facilitate thread-forming in less-compressible plastics while providing high resistance to strip-out and pull-out.
Features
Tri-roundular configuration that allows displaced material to cold flow back into relief areas.
45° profile allows thread to penetrate deeply into plastic material
Single lead design and narrow helix angle lowers drive torque and failure torque in stiffer plastics
Benefits
Reduces possibility of boss failure
Increases product reliability
Eliminates need for inserts and lock washers
Minimizes radial stress
Allows design of thinner bosses
Generates strong mating threads
Resists vibration loosening
Reduces probability of strip-out and pull-out
Achieves wide differentials between drive and fail torque
Creates less stress on the boss

Nickel electroplating is a technique of electroplating a thin layer of nickel onto a metal object. The nickel layer can be decorative, provide corrosion resistance, wear resistance, or used to build up worn or undersized parts for salvage purposes.
Nickel electroplating is a process of depositing nickel on a metal part. Parts to be plated must be clean and free of dirt, corrosion, and defects before plating can begin. To clean and protect the part during the plating process a combination of heat treating, cleaning, masking, pickling, and etching may be used. Once the piece has been prepared it is immersed into an electrolyte solution and is used as the cathode. The nickel anode is dissolved into the electrolyte in the form of nickel ions. The ions travel through the solution and deposit on the cathode.
