Product overview
- Supplier series: CM内六角扁平头机螺钉. CM is retained as the supplier designation, not a DIN or ISO standard.
- Material: 304 stainless steel. Source marking: unmarked; no property class is inferred.
- Metric machine threads; all captured entries are full thread.
- Finish: bright-cleaned (source: 洗光).
- Drive: hexagon socket. Socket size and depth require confirmation.
This machine-screw series is listed separately from CA self-tapping screws. Confirm head diameter, height, bearing profile, hexagon-socket dimensions, length units and measuring convention against the controlling drawing. No countersunk geometry, DIN/ISO equivalence or self-tapping capability is assigned.
