The prompt
Design Four standard M3 x 8 countersunk (flat head) hex socket screw, ISO 10642 style. Units cm. Thread: major dia 0.3, pitch 0.05, length 0.8 measured from the top of the head to the tip (head included, as for countersunk screws). Chamfered tip. Head: 90-degree countersunk cone, top dia 0.6, head height 0.17. Hex socket 0.2 across flats, 0.1 deep, in the centre of the flat top. Model as a single solid body. The thread can be a simplified cosmetic thread (plain 0.3 dia cylinder) if a real helical thread is difficult. The head must fit a countersunk hole of dia 0.32 in a 0.3 thick plate, and the screw tip must go into a 0.25 dia pilot hole. Export STEP + STL.
