M6x20 Button Head Socket Cap Screw with Flange A2 Stainless Steel ISO 7380-2

M6x20 button head socket cap screw with flange made of A2 (AISI 304) stainless steel is a reliable fastening element designed for mounting balustrades and structures where connection aesthetics and corrosion resistance are required. The button head with integral flange (washer) eliminates the need for a separate washer, which speeds up assembly and reduces the number of required components.
The internal hexagonal socket (Allen key) ensures secure tightening and enables work in areas with limited access. The low profile of the button head means the screw does not protrude above the mounting surface, guaranteeing a neat appearance of the connection — particularly important in balustrade elements and visible structures.

Application and Benefits
AISI 304 stainless steel (A2 grade) provides high corrosion resistance — the screw will perform well in both internal and external applications, without the risk of rust formation and staining on mounting surfaces. This is an important advantage wherever aesthetics and connection durability must go hand in hand — in balustrade systems, façade elements, stainless steel structures or mounting of installation elements.
The integrated flange increases the bearing surface area, which reduces the risk of damage to delicate materials and eliminates the need for an additional washer. For installation companies, this means fewer components to order, faster assembly of mounting sets and more efficient work on site.
