Exact Service Component
The exact Royce Ayr service-part identity is preserved so a visually similar fastener is not substituted.


Royce Ayr Knife Screw. Exact production data is tied to SKU 580.RH-M3505.9; stale legacy/private-label wording has been replaced where current Royce Ayr or verified catalogue data provides a stronger source.
Verified Royce Ayr configuration for industrial woodworking, CNC routing, boring, panel processing, or tooling service as applicable to this exact SKU.
Install only in the verified compatible Royce Ayr cutter system and match the exact thread, head, seat and tightening requirements before service.
The Royce Ayr Knife Screw 580.RH-M3505.9 is a verified non-cutting service component used within a compatible Royce Ayr indexable cutter system. It must be selected by exact part number rather than by visual similarity.
This component is not a carbide or PCD cutting tool. Its function is mechanical retention/service, so the long-description image uses a verified Royce Ayr parent-system visual rather than Titan’s cutting-material imagery.
Inspect mating threads, the cutter seat and the associated clamping components before installation. Replace damaged hardware rather than attempting to reuse rounded, stretched or contaminated fasteners.
