Hex Flange Nut Dedra NK-M8/KL-8 — M8 hexagonal nut with integrated flange

Dedra NK-M8/KL-8 — M8 hexagonal nut with integrated flange is a fastening component designed to combine the clamping function of a standard hex nut with the load-distributing properties of a washer. The integrated flange enlarges the contact area between nut and mating surface, reducing surface pressure and helping to prevent loosening in assemblies subject to vibration. This M8 flange nut is suitable for mechanical connections, furniture assembly, light automotive repairs and general fastening tasks where a built-in washer effect is preferred.

Advantages

The integrated flange increases bearing surface and distributes load more evenly than a standard hex nut, reducing material deformation under clamping. The one-piece design removes the need for a separate washer, simplifying installation and inventory. Its hexagonal profile allows use with common spanners and sockets, enabling reliable torque application and straightforward assembly in confined spaces. The flange shape also improves resistance to loosening caused by vibration when used with appropriate thread engagement.

Suitable for

• Mechanical assemblies and machinery mounting
• Furniture assembly and fittings
• Light automotive repairs and attachments
• Joining metal profiles, brackets and plates
• General maintenance and repair tasks requiring an integrated washer effect

Key specifications

• Thread size: M8
• Head type: hexagonal with integrated flange
• Material: steel (surface finish depends on supplier batch)
• Drive method: compatible with standard 6-point spanners and sockets
• Function: load-distributing flange provides washer-like bearing

How to use

Position the nut on the M8 threaded bolt or rod and hand-tighten until the flange seats against the mating surface. Use an appropriately sized spanner or socket to apply the required torque, taking into account the material and thread engagement to avoid over-tightening. For assemblies subject to vibration, ensure correct thread length engagement and consider using a complementary locking method if a specific vibration rating is required. Inspect the connection after initial loading and periodically during use to confirm tightness and integrity.

Usage recommendations

For reliable performance, match the nut to an M8 bolt with compatible thread pitch and material strength. When assembling into soft or painted surfaces, monitor flange contact to prevent surface indentation or coating damage. If corrosion resistance or a defined torque specification is required, select the appropriate material grade or finish and follow torque tables for M8 fasteners.
