About the 1720406 Socket Head Cap Screw M3x10, A4
This item is a hexagon socket head cap screw identified by the reference number 1720406 together with a plain-language description in the designation. Decoding that designation: the screw has a cylindrical cap head driven by an internal hexagon socket, an M3 thread, a 10 mm nominal length, and is made from A4-grade stainless steel — the molybdenum-bearing austenitic (316-type) grade selected where improved resistance to chlorides and marine atmospheres is wanted over standard A2. Socket head cap screws are the default high-clamp-force machine screw for precision assemblies because the head sits in a counterbore and the socket drive allows high installation torque in confined spaces. No dimensional-standard reference (such as a DIN or ISO number) is recorded in the designation, so none is claimed here; the stated size, head style and material govern.
