4-40 x 2 Brass Flat Head Socket Cap Screw supports panel and fixture designs that require a brass countersunk screw with top-side hex socket access.

Its nonferrous construction and machinable character make it useful in panels, fixtures, enclosures, and light-duty mechanical assemblies where brass is already specified. It may be used in decorative hardware, architectural components, and bracket assemblies when the design already calls for a brass countersunk socket fastener.

The countersunk profile helps designers keep covers, plates, and enclosures cleaner than they would be with raised drive hardware. For this 4-40 thread and 2 in. length, review the body diameter, head diameter, head height, hex socket size, and key engagement before approving the fastener for a countersunk assembly. Cold Headers supports quote and availability requests for unusual configurations where the exact thread, length, material, and head style matter.
