About the 1233785 Hex Socket Head Cap Screw
This 1233785 screw cap hex skt item is a hexagon socket head cap screw made to ISO 4762, the standard that specifies cylindrical-head socket screws with coarse pitch thread from M1.6 to M64 in product grade A. The thread is M3 with the coarse 0.5 mm pitch and the nominal length under the head is 6 mm, making it one of the shorter lengths in the M3 range and suited to shallow tapped holes or thin sheet fixed into an insert. The cylindrical head and internal hexagon allow the screw to be driven in a counterbore where a spanner cannot reach. Material is A4 austenitic stainless steel, the molybdenum-bearing group in ISO 3506-1, chosen where chloride exposure or wash-down conditions would attack a plated carbon steel screw.

Typical applications
Short M3 cap screws of this type fasten cover plates, retaining clips, small motor and sensor mounts and PCB brackets into tapped blind holes where thread engagement is limited. The counterbore-friendly cylindrical head lets the fastener sit below a machined surface. A4 stainless makes the screw suitable for humid, coastal and cleaning-chemical environments.
