What can I say? It's shiny and countersunk, with a machine screw thread. It's 40mm long and the thread is 4mm wide. They fit an M4 threaded hole just perfectly. Even though it's called a machine screw, you can use it anywhere with a suitable and deep enough threaded hole. How's that for versatility?

GETTING ELECTRICIANS OUT OF TR
When the M3.5 or 4BA female thread strip in a mounting box, especially the old metal ones with the plastic inserts, I use a M4 tap. These M4 CSK screws with relatively small heads are ideal. Pity they are not available in 30mm lengths for shallower boxes.
