Knurled nut DIN 6303-B6-A Z016180

Knurled nut – precision and secure grip

The knurled nut, made of steel according to DIN 6303-B6-A standard, is a connecting element providing stable and secure fastening. It is ideal for applications requiring frequent tightening and loosening without tools, as well as where comfort and ergonomics are important. The knurling on the circumference of the nut ensures an excellent grip, even with gloves.

Construction and application

The nut has a transverse hole (d5) that allows for securing against accidental loosening with a split pin. This is particularly important in applications exposed to vibrations or dynamic loads. Made of steel, it provides strength and resistance to mechanical damage.

• Applications:
  • Mounting machine and device components
  • Construction of measuring and control equipment
  • Assembly of furniture and steel structures
  • Automotive industry
  • Laboratory equipment

Characteristic features

The knurling on the nut has been designed with user comfort in mind. A larger knurl pitch than in standard DIN 6303 provides a better grip and easier manipulation, which will be appreciated by both installers and end-users. Additionally, the nut is available in steel version and in stainless steel AISI 303 NI (check availability). Sandblasted surface improves aesthetic properties and provides better adhesion of protective coatings. It is worth remembering that the smooth hole with H7 tolerance and the M12 thread size are not covered by the official DIN 6303 standard.
