Square Nut for Anchor Bolts

DIN 798 square anchor nuts are designed for use with anchor bolts and foundation bolts. The main application area is construction and erection of metal structures for buildings and other facilities.

The nuts are manufactured to the DIN 798 standard. Material: carbon steel or coated steel (hot-dip galvanized or electroplated zinc coating). Property class: 5, 8 or 10.

The choice of material and property class depends on operating conditions. Under increased loads or exposure to aggressive environments, nuts with electroplated zinc coating and a property class of at least 8 should be selected — they are resistant to moisture, temperature fluctuations and corrosion. If frequent tightening and loosening is not expected, a lower property class is acceptable.

DIN 798 nuts are available in the following sizes: thread diameter from M24 to M100, height 30–125 mm, width 50–165 mm.

Other nuts are available on the FLOK website.
