This spare screw is a direct replacement component for Tschorn 40mm slitting saw arbors. It threads into the arbor to clamp saw blades firmly in position, preserving the arbor's original true-running accuracy during cutting tasks.

• Exact 40mm Compatibility: Machined to match Tschorn arbor dimensions precisely, ensuring the blade stays centered without play or wobble.
• Secure Blade Retention: The flanged head and threaded shank deliver consistent clamping force that holds blades steady under load.
• German-Made Durability: Produced from hardened steel to resist wear from repeated tightening cycles and maintain reliable performance over time.

Keeping a spare screw on hand lets you restore full arbor function quickly if the original is lost or damaged, so your cutting setup stays accurate and productive without the cost of replacing the entire arbor.
