1/2-13 x 2 1/4 Brass Flat Head Socket Cap Screw is intended for applications where brass material and flat-head socket geometry are both called out by the drawing or bill of materials.

Because the drive is recessed, the screw can support a smooth exposed surface while still allowing socket-tool engagement during service. This makes the product useful for fixtures, housings, and low-load mechanical assemblies, especially where raised hardware could interfere with adjacent components.

Cold Headers supports quote and availability requests for unusual configurations where the exact thread, length, material, and head style matter. For sourcing, the important point is matching the brass material callout, thread size, length, countersunk geometry, and socket-drive requirements exactly. For this 1/2-13 thread and 2 1/4 in. length, review the body diameter, head diameter, head height, hex socket size, and key engagement before approving the fastener for a countersunk assembly.
