Knurled nut DIN 6303-B12-B Z016177

Knurled nut – precision and secure grip

The knurled nut, made of steel according to DIN 6303-B12-B standard, is a connecting element providing stable and convenient mounting. It is ideal for applications where manual tightening and adjustment without tools are required. The knurling increases friction, making it easier to rotate the nut even in difficult conditions.

Design and application

The nut has a transverse hole (d5) that allows for securing against accidental loosening with a pin. This is particularly important in applications exposed to vibrations or dynamic loads. This hole provides additional assurance that the connection will remain unchanged for a long time.

It is worth noting that the smooth hole with H7 tolerance and the M12 thread size are not officially included in the DIN 6303 standard, which indicates a refinement of the product by the manufacturer – ELESĘ + GANTER. The use of a larger knurling pitch than the standard DIN 6303 provides a better grip and user comfort.

Advantages and benefits

• Convenient installation: Knurling allows for quick and easy manual tightening, eliminating the need for tools.
• Connection safety: The transverse hole allows securing the nut against loosening, increasing the reliability of the structure.
• Durability: Steel construction guarantees high strength and resistance to mechanical damage.
• Precision manufacturing: Refinement of dimensions (H7 hole, M12 thread) in relation to the DIN 6303 standard ensures a perfect fit with cooperating elements.
• Better grip: Larger knurling pitch than in the DIN 6303 standard makes it easier to rotate the nut and provides a more secure grip.
