Metric Flat Head Socket Cap Screws

Flat head socket cap screws sit flush in a countersunk hole, giving a clean surface and clearance that a protruding head would not, which makes them a frequent choice for motor mounts and other close-fitting hardware. This category covers metric sizes with an internal hex drive.

Sizes and Lengths

The listings run in the small 2.0mm and 2.5mm diameters common on model hardware, in lengths from a few millimeters up through longer runs such as 12mm. That range lets you pick a screw that seats fully without bottoming out or leaving excess thread.

The socket cap drive accepts a hex key, which gives good grip in the tight quarters around a motor mount or firewall. Flat head screws also pull parts together as they seat into the countersink.

Check the diameters and lengths above to find the metric flat head screws your build calls for.
