Anchor A4

Anchor A4 (translated as “anchor”) lives up to its name structurally. It consists of two parts: a rod with external thread and a head (usually hexagonal), plus an expansion sleeve.

The fastener is made of high-strength stainless steel and is designed for installing various elements into concrete, dense brick or stone. Besides chromium and nickel, the source alloy contains up to 3% molybdenum, which significantly improves the key technical characteristics of the fastener.

The widest application area for A4 anchors is new construction and reconstruction of existing buildings and structures. This type of fastener is required when installing door and window units, mounting façade structures, and suspended ceilings. A specific anchor modification can be chosen for each type of work:

• drop-in;
• cast-in;
• wedge;
• ceiling;
• with a ring or hook on the head;
• with a nut.

Anchor A4 is used for building structures that operate under harsh conditions. It withstands high and low temperatures as well as any aggressive exposure, does not rust and is not magnetic. Unlike other grades, it is recommended for use in contact with acids, chlorine, and salt water.
