Key Features
- OEM-Grade Dimensional Accuracy — Manufactured to Husqvarna's exact tolerances, this pin maintains the tight clearances required for proper component alignment in a core drill assembly.
- Drop-In Replacement — Machined to match the original pin's diameter and length, this part seats directly into its bore without rework or modification to mating components.
- DM406 Core Drill Compatibility — Verified for the Husqvarna DM406 concrete core drill, so you can cross-reference part number 525353601 against your parts diagram with confidence.
- Alignment Integrity Restored — A correctly fitted parallel pin keeps paired components locked in their designed orientation, preventing the play or slippage that leads to premature wear of surrounding parts.
- Genuine Husqvarna OEM Part — Supplied as an authentic replacement, this pin meets the same material and hardness standards as the part it replaces, not a generic approximation.
A parallel pin is a precision-machined cylindrical fastener used to fix two or more components in exact alignment relative to one another. In a core drill like the DM406, parallel pins locate housings, gears, or bearing seats so that rotating and stationary parts maintain their correct positional relationship under load. When a parallel pin is worn, sheared, or missing, the components it aligns can shift, causing vibration, uneven loading, and accelerated wear to surrounding assemblies — ultimately affecting the accuracy and performance of the drill.
