Flat nuts

Die Co. flat nuts come in 25 standard formats – the most commonly requested sizes and designs or they can be customized for a specific application.

All of our flat nuts are made from spring steel and will not loosen due to vibration. Their self-locking design makes them easy to install and remove without special tools. And they are lower cost than most alternative fasteners. Flat nuts are a good option when physical space is limited.

Our flat nut product line also includes:

  • W nuts
  • Twin nuts – with various center-to-center distances
