Nickel Plated Tin Plated M4 Copper Bronze Hexagon Slotted Torx Cross Recess Hexagon Pan Head Metal Screw
This pan head screw is made from copper or bronze with a nickel or tin plating finish to enhance corrosion resistance and solderability. Drive options include slotted, Torx, cross recess, and hexagon head – offering flexibility for different assembly tools. M4 size suits precision electronics and instrumentation. Bronze provides higher hardness and wear resistance than pure copper while retaining copper alloy characteristics. Nickel plating gives a bright silver-white appearance; tin plating is grey-white with excellent solderability. The pan head provides a large bearing surface, suitable for plastic housings or thin sheet connections.
