Self-drilling screws are excellently suited for fast screwing of sectional sheets to steel substructures.

Self-drilling screws according to DIN 7504 – drilling, thread cutting and screwing in one action

Self-drilling screws have a hardened tip (partly with wings and ribs) which drill into various substructures – even steel. There is no need to pre-drill tap holes. Self-drilling screws are suitable for fast screwing of sectional sheets to steel substructures for example. Drilling, thread cutting and screwing in one action – all in up to 12 mm thick steel!

  • DIN 7504: Self-drilling screws with tapping screw thread or wings and ribs

Self-drilling screws are manufactured in double-stroke technique on our cold forming presses.

The hardened, partly winged tip drills a hole in the steel structure. The following tapping screw thread immediately cuts a metric thread into the resulting hole. The screw connection can be undone again later.

Time-saving assembly of sections on a steel substructure without pre-drilling and without nuts
