- DIN 1476–1477 · EN ISO 8746–8747
Additional Products
- Specialized Solutions & Custom Parts
Cylindrical pins, Kerpin H notched grooved pins, grooved pins, and Rikopin ring-head cylindrical pins. Complemented by a wide range of variants for diverse installation requirements.
- The KERPIN® principle
Superior holding power
With our patented design, complex, precise fits are a thing of the past. Simply drill a hole—physics does the rest.
Grooves through rolling
Three grooves, offset by 120°, are rolled into the pin, forming grooves that increase its diameter.
Elastic back-formation
Driving the pin into a straight hole forces the grooves back, creating a secure, radial tension.
Vibration-proof hold
High clamping forces ensure an absolutely vibration-proof fit, preserving the borehole and allowing for reusability.
