Washer head screws large steel flat washers pan washer head

Washer head screws is a flat washer just under the pan head of the screw and the washer is integrated with the head. The pan washer head design could possibly be the most versatile head design available. It combines the advantages of the pan head but has a washer built onto the head to increase head diameter and prevent over driving in softwoods while providing a maximum bearing surface. These fasteners have Square-Phillips combo recess drive designed to offer the dependability of a square drive recess with the convenience and after-market serviceability of a Phillips drive. In addition, they have coarse thread design for superior holding power while reducing splitting or crumbling of the material, allowing the fastener to install rapidly with full thread engagement after just one revolution. The threaded surface is nearly perpendicular to the screw axis, providing great resistance to pullout. Ever Hardware provides custom made washer head screws and customizable packaging.

Nickel electroplating is a technique of electroplating a thin layer of nickel onto the washer head screws. 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 form of nickel ions. The ions travel through the solution and deposit on the cathode.
