DIN6916 Structural Steel HV300 Round Washers
DIN 6916 Structural Washers are high-strength washers with a minimum hardness of HV 300, designed for use in preloaded bolted connections. Their hardened structure provides a suitable bearing surface for transferring the clamping force generated during tightening, while the washer geometry is matched to the corresponding structural bolt and nut.
The washer is used as part of a complete structural fastening assembly with DIN 6914 high-strength bolts and DIN 6915 property class 10 nuts. By providing a defined bearing surface around the bolt hole, the washer helps distribute the applied clamping force over the connected steel component and supports consistent installation of the bolted joint. DIN 6916 Structural Washers are available for structural steel applications such as steel frames, fabricated structures, industrial equipment, platforms, bridges, and other load-bearing bolted assemblies. The washer size should be matched to the nominal diameter of the structural bolt and the requirements of the connection.
Specification:
DIN 6916 Structural Washers are manufactured for high-strength structural bolting systems and are characterized by their defined dimensions and minimum hardness of HV 300. The hardened washer provides a stable bearing surface under the clamping force generated during installation, helping prevent excessive deformation around the bolt hole. The washer dimensions are matched to the corresponding structural bolt size. For a complete high-strength connection, DIN 6916 washers are used with DIN 6914 bolts and DIN 6915 nuts, with the bolt, nut, and washer selected as a compatible assembly.

Dimension Chart of DIN6916 Structural Steel HV300 Round Washers:
The DIN 6916 dimension chart provides the main measurements required to match the washer with the corresponding structural bolt. The key dimensions include the nominal washer size, inner diameter, outer diameter, and washer thickness. The washer size should correspond to the nominal diameter of the DIN 6914 structural bolt. Correct inner diameter and bearing dimensions help ensure proper seating around the bolt hole and provide an appropriate surface for transferring the clamping force during installation.

Application of DIN6916 Structural Steel HV300 Round Washers:
DIN 6916 Structural Washers are used as part of high-strength and preloaded bolted connections, where a defined bearing surface is required between the fastening component and the connected steel member. The washer helps distribute the clamping force around the bolt hole and provides a stable contact surface during tightening.
Structural Steel Connections
DIN 6916 washers are used with DIN 6914 bolts and DIN 6915 nuts in steel columns, beams, trusses, frames, steel platforms, and fabricated structural connections. They form part of the complete fastening assembly rather than functioning as a general-purpose flat washer.
Industrial Steel Structures
They are suitable for industrial equipment frames, support structures, machinery bases, steel platforms, and heavy fabricated assemblies where high-strength bolted connections are required. The hardened washer surface helps maintain the required bearing condition during tightening.
Bridges and Heavy Steelwork
DIN 6916 washers can also be used in bridge steelwork, infrastructure structures, large steel fabrications, and other load-bearing steel assemblies, subject to the applicable design and installation requirements.
