Kit EN 14399-4 M16x45 10,9 (bolt+nut+2pucks) zinc hot

High-strength structural bolts (bolt sets) are a type of fasteners used to connect elements of critical structures and ensure the resistance of the components of these structures to loads. Structural bolts have an enlarged hexagonal head and are supplied in sets with a correspondingly enlarged structural nut and two washers. All elements of the set are marked HV (10.9) or HR (8.8/10.9). These are two systems of structural fasteners, the elements of which should not be mixed with each other so that the performance characteristics of the bolt sets are not impaired.

Applications where a pre-tensioned connection is required (preloaded connection), which is formed by tightening the set to the manufacturer's nominal tension values.

Material High-strength structural alloy steel.

Hot-dip galvanized zinc coating protects against corrosion if the fasteners are to be used in aggressive environments
