Serrated Flanged Hexagon Nuts (DIN 6923) - Marine Stainless Steel (A4)
Current norm: DIN 6923
Equivalent norms: GB6177
Serrations bite into material for mild vibration resistance while the flange eliminates the need for a separate washer.
These nuts are ideal for securing screws in oversized or irregularly shaped holes since the flange covers a larger area than standard nuts.
You can use them again and again without sacrificing strength.
However, the serrations may mar the surface of your material.
Also known as collar nuts.
