Product Description
CMT Screw for Bearing - TCEI M4 x 12 x 16mm (Diameter: 7mm) is a precision-spec replacement fastener designed to secure bearings on CMT router bits and cutter heads. With an M4 TCEI hex socket head configuration, this small but critical component keeps bearing assemblies firmly in place during high-speed routing operations - helping maintain accuracy, safety, and smooth performance cut after cut. Whether you are replacing a worn fastener or stocking a spare for your CMT tooling lineup, this screw delivers an exact-fit solution engineered to CMT's exacting standards.
Key Features
- TCEI hex socket head design - allows secure tightening with an Allen/hex key, reducing the risk of cam-out and making bearing replacement faster and more reliable on the workbench.
- M4 x 12 x 16mm thread specification - provides a precise, compatible fit for CMT router bits that use M4 TCEI bearing screws, eliminating guesswork when sourcing a replacement.
- 7mm head diameter - sized to sit flush and properly engage the bearing seat, helping maintain correct bearing positioning and reducing unwanted lateral movement during routing.
- OEM CMT part (MPN: 990.061.00) - a genuine replacement component, ensuring compatibility with the original tooling design and preserving the performance integrity of your CMT router bit or cutter head.
Why This Product
- Sourcing an exact-match bearing screw matters - using the correct M4 TCEI specification means the fastener threads properly into the CMT router bit body without risk of stripping or cross-threading, protecting your investment in quality tooling.
- The TCEI hex socket drive style gives you confident torque transfer when seating or removing the bearing, which is especially valuable during routine maintenance or bit changeovers in a production shop environment.
- With a 7mm head diameter precisely matched to CMT's bearing retention design, this screw helps keep the bearing centered and secure - directly supporting cleaner cuts and longer bearing life.
- Ordering a genuine CMT replacement screw (990.061.00) means no guessing about dimensional tolerances - the part is manufactured to fit the same specifications as the original, so your router bit performs as intended from the first pass.

Frequently Asked Questions
What does TCEI mean on this bearing screw?
TCEI refers to the hex socket (Allen head) drive style of the screw. This type of fastener is tightened and loosened using a hex key, providing strong, centered torque transfer and reducing the likelihood of slipping or damaging the screw head during installation or removal.
Which CMT router bits and cutter heads does this screw fit?
This screw is designed for CMT router bits and cutter heads that use M4 TCEI bearing retention screws. If your existing bearing screw matches the M4 x 12 x 16mm specification with a 7mm head diameter and a hex socket drive, this is the correct replacement part.
What is the significance of the 7mm head diameter on this screw?
The 7mm head diameter is matched to the bearing seat dimensions on compatible CMT tooling. Using a screw with the correct head diameter ensures the bearing is held securely in position without rocking or shifting, which is essential for accurate routing and long bearing life.
Is this a genuine CMT replacement part?
Yes. This screw is an authentic CMT component carrying CMT's own part number 990.061.00, manufactured to the same dimensional specifications as the original hardware found on compatible CMT router bits and cutter heads.
