About the 1233815 Fastener
This item is a hexagon socket head cap screw to ISO 4762 in thread size M3, 12 mm long, manufactured in A4 stainless steel and listed under Bossard article number 1233815, as designated in the product name. ISO 4762 defines the familiar cylindrical-head cap screw driven by an internal hexagon socket, a geometry chosen where a compact head, high preload and driving access from directly above are needed — including counterbored assemblies. A4 identifies the acid-resistant austenitic stainless steel grade used for marine and chemically exposed environments, offering higher corrosion resistance than the A2 grade. Bossard is a Swiss fastener manufacturer and distributor whose article numbers, like 1233815 here, identify a specific standard part, size and material combination within its catalogue.
