Countersunk screws to DIN 7991 / ISO 10642 have a countersunk head with a hexagon socket: the head sits fully inside the counterbore and the surface stays flush. In stock we carry the size M8x60 with full thread in steel 8.8, Geomet-coated. Further sizes up to M12, including stainless steel, are available on request.

Frequently asked questions
Which standard do the countersunk screws comply with?
The countersunk screws comply with DIN 7991 / ISO 10642 – countersunk head with hexagon socket, full thread.
What is the difference between DIN 7991 and ISO 10642?
It is the same screw: ISO 10642 is the internationally harmonized equivalent of the German standard DIN 7991. Dimensions and head shape are identical.
What is a countersunk screw used for?
The countersunk head disappears completely into the countersink so that the joint finishes flush and nothing protrudes above the surface. That is required wherever people walk or drive over the surface or where it is cleaned – for example on gratings and covers.
Which dimension and property class is in stock?
In stock in this shop: M8 x 60 mm in steel 8.8, Geomet-coated. From the ARNELL range on request: M4 to M12, steel 8.8 and 10.9, stainless steel 1.4301 and 1.4404, Geomet-coated or electroplated.
What is a Geomet coating?
Geomet is a thin zinc flake coating. It is more dimensionally accurate than hot-dip galvanizing and avoids the risk of hydrogen embrittlement on high-strength screws – which makes it the matching surface for property class 8.8.
