Countersunk screw M6x20 A2 DIN 7991 – hexagon socket, stainless steel
Description
Countersunk screw M6x20 A2 DIN 7991 – hexagon socket, stainless steel
Countersunk screw M6x20 manufactured from A2 stainless steel (AISI 304) is a reliable fastening element designed primarily for balustrade systems. Thanks to the DIN 7991 standard and hexagon socket, it ensures precise tightening and an aesthetic, flush profile after installation — the countersunk head sits flush in the countersunk recess, not protruding above the surface.
Austenitic stainless steel AISI 304 (marking on head A2-70) guarantees high corrosion resistance — both in internal conditions and externally on buildings. This makes the screw perfect for mounting terrace, balcony and staircase balustrades, where fastening elements are exposed to moisture and changing atmospheric conditions.

Application and advantages
The DIN 7991 screw with hexagon socket is particularly valued by installation teams for the convenience of tightening with an Allen key and for the fact that the countersunk head creates a smooth, even surface when recessed into the material. This is an ideal solution wherever connection aesthetics matter — in stainless steel balustrades, handrail brackets, post fixings and balustrade accessories.
- Countersunk head — after installation does not protrude above the surface, maintaining a clean appearance of the structure
- Hexagon socket — secure and convenient tightening with Allen key, even in hard-to-reach places
- A2 stainless steel — corrosion resistance without the need for additional surface protection
- DIN 7991 compliance — full interchangeability with other screws in this standard, easy availability of matching countersunk recesses
