Key Features
- Genuine OEM Dimensional Accuracy — manufactured to Husqvarna's exact 4x22 specification, ensuring the pin seats and retains components correctly without play or misalignment.
- Direct Drop-In Replacement — engineered to the same form factor as the original, allowing straightforward installation into the existing bore without modification.
- Broad Wall Saw Compatibility — fits the WS440, WS440HF, WS460, WS462, WS463, and WS482 wall saws, covering a wide range of Husqvarna track-mounted wall saw models.
- Secure Component Retention — a properly seated spring pin holds assemblies in alignment under the vibration and load cycles typical of wall saw operation, preventing unwanted movement or component separation.
- OEM Parts Assurance — sourced directly through the Husqvarna parts network, so you receive the correct part the first time and avoid fitment guesswork on the job.
A spring pin — also called a roll pin or slotted spring pin — is a small cylindrical fastener with a longitudinal slot that allows it to compress slightly as it is driven into a bore, then spring outward to grip the surrounding material. This tension fit locks shafts, linkages, or other assembly components in precise relative positions, preventing rotation or axial movement during operation. When a spring pin shears, deforms, or works loose, the components it was securing can shift or disconnect, leading to misalignment, loss of function, or accelerated wear on adjacent parts.
