Key Features
- Genuine OEM Material Spec — Manufactured to Husqvarna's exact hardness and dimensional tolerances for a Spring Pin, ensuring consistent retention force and resistance to shear under load.
- Drop-In Replacement — Matches the original bore diameter and pin length for direct installation without modification, maintaining correct component alignment throughout the assembly.
- PG400 Floor Grinder Fitment — Confirmed for the PG400 planetary floor grinder; cross-reference part number 721425901 against your parts diagram before ordering to ensure correct application.
- Restores Positive Component Lock — A correctly fitted Spring Pin holds assembled parts in their designed position, preventing unwanted movement or misalignment during grinding operation.
A Spring Pin is a hollow, slotted cylindrical fastener that compresses slightly upon installation to grip the bore walls with consistent radial tension. It is used to lock shafts, collars, or linkage components in their correct position within an assembly, transmitting torque or retaining alignment under vibration and operational loads. When a Spring Pin wears, fractures, or works loose, the components it secures can shift or separate, leading to imprecise operation, accelerated wear on surrounding parts, and potential damage to the assembly if left unaddressed.
