M5 x 12 x 20 Rändelmutter Stiftloch DIN 6303 Stahl

NOTE: To pin this thumb nut to a threaded shaft, drill through the pre-drilled hole and then ream during the assembly process. See the column in the data table for the suitable dowel pin size.

These metric knurled nuts, machined from solid Steel bar, feature a knurled surface providing a reliable grip. The black oxidised finish enhances corrosion resistance. Aligned with DIN 6303 standards but featuring variations in knurling pitch and depth, these nuts provide reliable performance.

Available in a range of metric thread sizes from M5 through to M12, these nuts cater to various engineering needs. The metric sized threads, combined with the robust one piece construction, makes them ideal for applications in mechanical engineering, automotive, aviation, manufacturing, and electronics.

The dowel bore d5 in these knurled nuts is purposefully designed for the utilisation of clamping or notch pins. This feature enhances their applicability in scenarios requiring additional clamping or notching functionalities, further expanding their scope of use.

In mechanical assemblies, these steel nuts provide a firm and secure fit, while the adaptability to different metric thread sizes ensures compatibility across diverse projects. From delicate electronics to heavy machinery, their versatility shines, offering a dependable fastening solution.

Alternative names: textured nuts or grip-enhanced nuts.
