About the 1233211 Socket Head Cap Screw M4x12, A2
Bossard article 1233211 is a hexagon socket head cap screw from the BN 610 range, the Bossard standard for fully threaded socket head cap screws produced to ISO 4762 and the withdrawn DIN 912 in A2 stainless steel. Distributor data for this article gives an M4 thread with a 0.7 mm pitch, a 12 mm nominal length, a cylindrical (cheese) head and a 3 mm hexagon socket drive. The cylindrical head with an internal hex drive lets the screw be tightened inside a counterbore or a confined pocket where a spanner could not reach an external hex, and the full thread means the screw grips along its entire length in a tapped hole. Bossard notes that the commercial quality of stainless grade A2 is property class 70, a tensile strength of 700 N/mm2. As a catalogued standard part it is made to consistent dimensional and material requirements.

Typical applications
M4 socket head cap screws fasten brackets, covers, enclosures, jigs and payload mounts across machine building, UAV and general industrial equipment. A 12 mm length suits thin plate into a tapped boss, or a stack of two light components, without the screw bottoming out. The A2 stainless grade makes this a routine MRO and production stock item for indoor and general outdoor service where a plated carbon-steel screw would corrode.
