Knurled nut DIN 6303-B8-B Z016183

Knurled nut – precision and secure grip

The knurled nut, made of steel according to DIN 6303-B8-B standard, is a fastening element providing stable and convenient mounting. The knurling on the circumference of the nut enables quick and secure grip, even with gloves – which is particularly important during assembly and adjustment.

This type of nut finds wide application in machines, devices and structures where frequent tightening and loosening without tools is required. The steel construction guarantees durability and resistance to mechanical damage.

• Durable material: Made of steel, ensuring long-term reliability in various working conditions.
• Knurled surface: Facilitates assembly and disassembly without the need for tools, increasing work efficiency.
• Cross hole: Features a cross hole d5, which allows securing the nut against self-loosening with a locking pin. This additional security is particularly important in applications exposed to vibrations or dynamic loads.
• Precise manufacturing: Compliance with DIN 6303-B8-B standard guarantees dimensions and quality of workmanship, ensuring compatibility with other fastening elements.
• Sandblasted surface: Provides better adhesion and aesthetic appearance.

It is worth noting that the smooth hole in tolerance H7 and the thread size M12 are not officially included in the DIN 6303 standard. Additionally, the knurl pitch has been deliberately increased compared to the standard DIN to provide an even better grip during manual tightening. This minor modification significantly affects the comfort of use and the safety of the connection.
