Countersunk screw M6x12 mm A2 DIN 7991 – hexagonal socket, stainless steel

Countersunk screw M6x12 DIN 7991 in stainless steel A2 (AISI 304) is a reliable connecting element used in mounting balustrades, handrails and steel structures. Thanks to the countersunk head, the screw sits flush with the mounting surface when tightened, providing a smooth, aesthetic finish — essential in visible balustrade and architectural connections.

The hexagonal socket (Allen key) enables precise tightening with an Allen key and guarantees secure tool grip even in hard-to-reach places. The screw is manufactured in accordance with DIN 7991 standard, which ensures dimensional repeatability and compatibility with other mounting system components.

AISI 304 (A2) stainless steel provides high corrosion resistance — the screw performs well both indoors and outdoors, in contact with moisture and atmospheric factors. Manufacturer Viraj is a recognised supplier of stainless steel fasteners.

Technical specification

Application

The screw is primarily intended for mounting balustrades and handrails, connecting steel structure elements and securing accessories where a flush connection with the surface is required. The countersunk head allows for a flat connection finish, eliminating protruding elements and increasing safety of use.
