Key Features
- Genuine OEM Specification — manufactured to Husqvarna's exact dimensional and material tolerances, ensuring the Spring Pin seats and functions exactly as the original component
- Direct Drop-In Replacement — engineered to install into the original location without modification, maintaining correct retention and alignment within the assembly
- Broad Power Cutter Compatibility — fits K650, K700, K540, and K650CutnBreak power cutters, covering multiple models within Husqvarna's handheld cutting range
- Restored Mechanical Integrity — a correctly fitted Spring Pin maintains secure component engagement; a worn or missing pin can lead to looseness, misalignment, or failure of the retained assembly
A spring pin is a small but critical fastening component used to secure and locate parts within a mechanical assembly. It works by flexing slightly on insertion to grip the surrounding bore, holding components in precise alignment under load and vibration. When a spring pin wears, deforms, or goes missing, the parts it retains can shift or disengage, leading to accelerated wear or functional failure of the larger assembly.
