The Wacker Neuson Wing Nut with Nonmetal Insert is a genuine OEM component designed for the BTS 13 and BTS 11 gasoline cut-off saws. As a direct factory replacement, this part is manufactured to the same specifications as the original, ensuring it seats and torques correctly on your machine. It fits the BTS 13 cut-off saw with 1-inch arbor and the BTS 11 cut-off saw with 7/8-inch arbor. Sourcing the correct OEM wing nut keeps blade changes fast, safe, and consistent out in the field.
Key Features
- Integrated Nonmetal Locking Insert — The nylon insert creates controlled thread resistance, helping the nut stay firmly seated under the vibration and torque loads typical of cut-off saw operation.
- Genuine Wacker Neuson OEM Part — Manufactured to the same specifications as the original hardware, so thread pitch and seating dimensions match the blade arbor exactly as intended.
- Hand-Tool-Free Blade Changes — The wing design allows for tool-free tightening and removal, keeping blade swaps quick without sacrificing holding strength.
- Fits BTS 13 and BTS 11 Cut-Off Saws — Confirmed fitment for the BTS 13 (1-inch arbor) and BTS 11 (7/8-inch arbor) gasoline cut-off saw models.
- Blade Retention Safety — A correctly functioning wing nut is critical to secure blade mounting; a worn or stripped nut can allow blade movement during operation, creating a serious safety hazard.
The wing nut with nonmetal insert is the fastener that secures the cutting blade to the arbor shaft on a cut-off saw. The hand-tightenable wing profile lets operators remove and swap blades quickly without additional tools, while the nonmetal insert in the threaded bore applies locking friction to prevent the nut from backing off under the constant vibration of the engine and blade. When this nut becomes worn, cross-threaded, or loses its locking insert integrity, blade retention is compromised — making prompt replacement essential for both machine performance and operator safety.
