Key Features
- OEM-Grade Material and Dimension — Manufactured to Husqvarna's exact 3/16" x 1" specification, ensuring the correct bend radius, pin diameter, and leg length for a secure lock in the designated bore.
- Direct Drop-In Installation — Matches the original mounting point exactly, inserting and spreading without any modification to the surrounding hardware or pin-retaining bore.
- Broad Floor Saw Compatibility — Fits the FS6600D, FS6800D, FS8400D, FS6600DT, FS6600DJDT, and Pro65G floor saw models, covering a wide range of Husqvarna walk-behind slab saws.
- Retains Critical Moving Assemblies — A properly seated cotter pin keeps shaft-mounted components locked in position under the vibration and load conditions typical of concrete cutting operations.
- Genuine Husqvarna OEM Part — Sourced directly from Husqvarna's construction equipment parts catalog, this component meets the same quality standards as the pin originally installed at the factory.
A cotter pin is a small but essential fastener used to secure pins, bolts, and shaft-mounted components from backing out or rotating under load and vibration. In a walk-behind floor saw, these fasteners hold assemblies in place through the continuous stress of cutting concrete and asphalt, where vibration is constant and component movement can lead to accelerated wear or mechanical failure. A missing, bent, or fatigued cotter pin can allow critical hardware to shift or separate, compromising both machine function and operator safety — making timely replacement with the correct OEM part the right call.
