Key Features
- Genuine OEM Retention Integrity — manufactured to Husqvarna's exact specifications, ensuring the spring cotter maintains correct clamping tension and holding force within the assembly
- Direct Drop-In Replacement — engineered to match the original mounting position and pin dimensions, allowing installation without any modification to the surrounding components
- Broad Fitment Across Two Machine Families — compatible with K535i, KV03, KV03MKII, and K40 power cutters, as well as MS360, MS360G, TS70, and TS90 tile and masonry saws
- Secure Component Retention — a functioning spring cotter locks adjacent parts firmly in place during operation; a worn or missing cotter can allow unintended movement, leading to assembly loosening or component damage
- Operational Safety — on power cutters and masonry saws operating under load and vibration, a correctly seated spring cotter is critical to keeping fastened assemblies secure and preventing in-use failures
A spring cotter is a small but essential retaining fastener used to lock a pin, shaft, or bolt in position within a mechanical assembly. It works by passing through a hole in a fastener or shaft and spreading outward to resist backing out under vibration and load. On power cutters and tile and masonry saws, which generate significant vibration during cutting, a properly installed spring cotter prevents critical fasteners from working loose. When a spring cotter becomes bent, fatigued, or missing, the components it secures can shift or disengage, potentially causing damage to surrounding parts or creating an unsafe operating condition.
