Key Features
- STEI pin drive style - provides a secure, tool-specific engagement that helps prevent cam-out when tightening or removing the bearing fastener during maintenance
- M6 x 16 mm thread size - matches the factory specification for compatible CMT router bits and cutter heads, ensuring a proper fit without modification
- UNI-5925 standard compliance - conforms to a defined dimensional and mechanical standard, so the screw delivers consistent performance and interchangeability with other UNI-5925 compliant hardware
- Designed specifically for bearing retention - keeps bearings correctly positioned under load, which directly supports safe cutting performance and extends the service life of your tooling
Why This Product
- A bearing that is not properly secured can shift during a cut, leading to inaccurate results or unsafe tool behavior - this CMT replacement screw restores the correct retention hardware so your tooling performs as intended
- The UNI-5925 standard specification means there is no guesswork about fit - the M6 x 16 mm dimensions are defined and verifiable against your existing hardware
- Sourcing a genuine CMT replacement part maintains the design integrity of your router bits and cutter heads, avoiding the dimensional mismatches that can come from using non-OEM fasteners
- Having a replacement bearing screw available as a spare part means routine maintenance or a field repair does not require putting your entire cutter head out of service while waiting for parts
