DIN 798 Square Anchor Nut, Galvanized, for Anchor Bolts

The DIN 798 standard covers a square-shaped steel nut for use together with anchor bolts, threaded studs and other types of fasteners. The hole with internal metric thread provides a strong threaded connection. This fastener is used in construction for securing structural elements, as well as in industry: the square shape is convenient for installing the nut into a mounting hole with protection against turning.

Materials and specifications

The fastener is made of carbon steel in property classes 5, 8 or 10 — the choice depends on the application and installation conditions. The product can be supplemented with a protective anti-corrosion coating of a thin zinc layer applied by hot-dip galvanizing. It is also produced from brass or stainless steel grades A2 and A4 — such fasteners are suitable for use in highly corrosive environments.

Main specifications of the nut:

• Thread diameter in the hole — from M24 to M100.
• Product height — from 30 to 125 mm.
• Width across flats — from 50 to 125 mm.

Applications

Anchor nuts are used to secure parts in slotted joints together with various types of threaded fasteners. They are used in heavy machinery, shipbuilding, machine-tool manufacturing and other industries, as well as in construction and installation work.
