Knurled nut DIN 6303-B8-A Z016182

Knurled nut – reliable and precise fastening

The knurled nut, made of steel according to DIN 6303-B8-A standard, is a connecting element providing secure and convenient fastening. The knurling on the circumference facilitates turning the nut even in difficult conditions, and also ensures a firm grip during manual tightening. This is an ideal solution for both professionals and end-users who value functionality and durability.

Design and application

This nut finds wide application in machines and devices where frequent tightening and loosening without tools are required. The transverse hole (d5) allows for additional securing of the nut with a pin, which increases resistance to accidental loosening during operation. 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 demonstrates the manufacturer's attention to precision. The use of a larger knurling pitch than the standard DIN provides a better grip and user comfort.

Advantages and benefits

• Comfortable grip: the knurled surface allows for easy manual rotation of the nut.
• Safety: possibility of securing the nut with a pin through the transverse hole.
• Durability: made of steel, ensures long-term use even in demanding conditions.
• Precision: thanks to the H7 tolerance and M12 thread size, it ensures an accurate fit to the screw.
• Versatility: ideal for use in machines, devices and other structures requiring frequent assembly and disassembly.
• Sandblasted surface: provides better adhesion and an aesthetic appearance.
