4-40 x 1 1/4 Brass Flat Head Socket Cap Screw is a brass flat head socket cap screw for assemblies that use a prepared countersink to reduce surface projection.
The internal hex drive supports installation from above the workpiece, which is useful in compact layouts where side wrench clearance is limited. This makes the product useful for electrical enclosures, control panels, and communication equipment, especially where raised hardware could interfere with adjacent components.
Cold Headers helps industrial distributors, sourcing teams, and maintenance operations identify uncommon lengths and specialty socket products. Brass selection should reflect the mechanical, electrical, environmental, and dimensional requirements of the assembly rather than substitution for steel or stainless hardware. For this 4-40 thread and 1 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.
