Knurled nut DIN 6303-B5-B Z016179

Knurled nut – precision and secure grip

The knurled nut, made of steel according to DIN 6303-B5-B standard, is a connecting element providing stable and secure fastening. Its construction combines the strength of steel with the convenience of manual tightening thanks to the knurled surface. This is an ideal solution for both professionals and end-users who value functionality and durability.

Construction and application

The knurling on the circumference of the nut allows for easy grip and precise tightening without the use of tools. This is particularly useful in situations where access to the screw is limited or when quick and frequent adjustment of the connection is required. Additionally, the presence of a transverse hole (d5) allows for securing the nut against self-loosening with a pin – increasing the safety and reliability of the connection.

These types of nuts find wide application in:

• Machines and equipment – as fastening elements for panels, covers or structural elements.
• Laboratory and measuring devices – where precision adjustment is key.
• Furniture – especially in structures requiring frequent disassembly or adjustment.
• Household appliances – as elements for fastening housings or internal components.

Characteristic features

• Durable steel: Ensures high resistance to mechanical loads and corrosion.
• Knurled surface: Enables convenient manual tightening, eliminating the need for tools.
• Transverse hole: Allows for additional securing of the nut against loosening with a pin.
• Compliance with DIN 6303-B5-B standard: Guarantees dimensions and properties consistent with a recognized standard.
• Sandblasted surface: Increases adhesion and improves the appearance of the nut. It is worth noting that the knurl pitch has been adapted for a better grip compared to the DIN 6303 standard.
