Knurled nut DIN 6303-M12-A-NI Z016188

Knurled nut DIN 6303 – reliable fastening in harsh conditions

The DIN 6303 knurled nut made of stainless steel is a fastening element that finds application in many industries – from automotive and construction to machinery and equipment production. Its design ensures secure and convenient fastening, and the knurled surface makes it easy to turn even with gloves on or in conditions of limited visibility.

Design and application

This nut, compliant with DIN 6303, features a metric M12 thread. It is made of stainless steel AISI 303 NI, which guarantees high corrosion resistance and the ability to work in an aggressive environment. Additionally, it has a transverse hole with a diameter of d5, which allows securing the nut against self-loosening with a locking pin. This is particularly important in applications exposed to vibrations or dynamic loads.

The knurling on the nut surface is wider than standardly specified in DIN 6303. The increased knurl pitch provides a better grip and comfort during manual tightening or loosening – which will be appreciated by both installers and end-users. The nut surface is sandblasted, which further improves its anti-slip properties.

• Applications:
  • Fastening structural elements
  • Assembly of devices and machines
  • Construction of industrial installations
  • Automotive industry
  • Outdoor applications (thanks to corrosion resistance)
