Spiral Pin

The Husqvarna Spiral Pin (OEM 720 18 28-51) is a genuine Husqvarna replacement spiral pin for Husqvarna DS 500 and DS 900 diamond core drill motors. Spiral pins are coiled spring pins that are pressed into a hole to locate or retain components, holding them securely while absorbing shock and vibration.

Pins can shear, wear or be lost during repairs, and a damaged or missing pin can let components move out of position. Fitting the correct genuine pin keeps the assembly secure and working as designed.

FUNCTION AND OPERATION

• Locates and retains components in the assembly.
• Coiled spring design grips securely in the hole.
• Absorbs shock and vibration in use.
• Genuine Husqvarna part for a correct fit.
• Replaces a sheared, worn or missing pin.
