Description
Countersunk head screw M6x16 DIN 7991 – stainless steel A2 (AISI 304), hexagonal socket

Countersunk head screw M6×16 DIN 7991 made from stainless steel AISI 304 (A2) — a reliable fastening element designed for professional applications in balustrade systems, aluminium constructions and installations requiring corrosion resistance. The countersunk head with hexagonal socket (hex key) allows for mounting flush with the surface, ensuring an aesthetic and secure appearance of the finished construction.
Standard DIN 7991 guarantees full dimensional repeatability and compatibility with typical countersunk holes used in profiles and balustrade elements. Thanks to the use of A2 (AISI 304) steel, the screw maintains full corrosion resistance in both internal and external conditions — it performs perfectly in installations exposed to moisture and variable atmospheric conditions.

Application
The screw is primarily intended for mounting elements of balustrade systems — brackets, supports, connectors and handrail fixings. The countersunk head sits in a countersunk recess, so it does not protrude beyond the mounting surface. The universal M6 thread ensures compatibility with a wide range of profiles and accessories available on the market. It will also work well in stainless steel and aluminium constructions, as well as in photovoltaic installations where a low-profile anti-corrosion connection is required.
