KNURL PIN

A KNURL PIN is a fastening component with straight, diagonal, or diamond-pattern knurling formed on the surface of the pin. After being pressed into a mating hole, the knurled teeth engage with the hole wall and increase friction, making it suitable for positioning, anti-rotation, joining, and retention applications.

Provides Secure Press-Fit Retention

When the knurled teeth are pressed into the hole wall, they create mechanical engagement that increases pull-out resistance and helps reduce the possibility of loosening during use.

Provides Anti-Rotation Performance

The surface knurling increases friction between the pin and the hole wall, helping restrict relative rotation between components. It is suitable for knobs, gears, and various connecting parts.

Simplifies the Assembly Process

KNURL PINS generally do not require threads, nuts, or additional fastening components. Assembly can typically be completed by press-fitting, helping reduce the number of parts required.

Multiple Knurl Designs Available

Straight, diagonal, or diamond knurling can be selected according to material, hole tolerance, and retention requirements. The knurl position and knurled length can also be customized.

Wide Range of Applications

KNURL PINS are commonly used in electronic and electrical equipment, automotive and motorcycle components, furniture, hardware tools, plastic assemblies, automation equipment, and precision machinery.
