DIN 6921 Bolts

Characteristics:

• DIN 6921 Bolts are available with a flat flange or a flange with locking teeth.
• Flange can be made with incisions or without incisions.
• Consist of a rod with full or incomplete metric thread and a hexagon head with a flange on the side of the rod.
• Complies with ISO 8102 International Standard, EN 1665, EN 14219.
• Strength Class 5.8, 8.8 and 10.9.
• The Bolt is installed in the mounting hole, where the nut is tightened from the reverse side.

Advantages:

• The presence of threads helps to prevent the bolts from loosening when exposed to vibration due to high frictional force between the flange and the attachment element.
• A smooth flange increases the area of the clamping surface of elements.
• Ensure the durability and strength of detachable threaded connections.
• Provide reliable protection against unscrewing operations.

Application:

• Used together with nuts and washers to connect and fasten parts and structures.
• Used for mounting, joining, fixing structural elements and equipment together with nuts of appropriate thread size.
• Capable of safely withstanding a great tightening force.
• Recommended to create detachable connections in engineering, construction, instrumentation and in other industries.
• Used for assembly works of complex and simple mechanisms, structure, pipelines and sanitary devices.
