Nickel Plated Tin Plated M4 Copper Bronze Hexagon Slotted Torx Cross Recess Hexagon Pan Head Metal Screw

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.

• Electronic component mounting – tin-plated copper screws can be soldered for PCB assembly.

• Instrument housings – nickel-plated bronze is wear-resistant and bright.

• RF shielding enclosures – copper screws provide good conductivity for grounding.

• Marine electronic equipment – bronze resists seawater corrosion.

• Transformer terminals – tin plating improves contact resistance.

• Copper/bronze base – excellent conductivity; bronze is more wear-resistant.

• Nickel or tin plating – enhanced corrosion resistance; tin plating adds solderability.

• Multiple drive options – suits various assembly tools and preferences.

• Pan head design – large bearing surface protects soft materials.

• M4 precision size – ideal for electronics and instrumentation.
