Product Description
CMT Screw for Bearing - Torx T15 TBTI M3.5 x 6 x 8.5mm (Diameter: 7mm) by CMT is a precision replacement fastener engineered to secure bearings on CMT router bits and cutter heads. This Torx T15 drive screw provides a reliable, tool-matched connection that minimizes cam-out and ensures consistent clamping force every time a bearing is installed or swapped out. Keeping a supply of these small but critical fasteners on hand means your router bit maintenance stays on schedule without downtime.
Key Features
- Torx T15 drive interface - the six-point star profile distributes torque evenly, reducing the risk of fastener or driver damage during tightening and removal compared to standard hex or Phillips drives
- TBTI screw designation - indicates a thread-forming bearing retention screw specifically engineered to engage the mating threads in CMT tooling bodies with the correct pitch and engagement length
- M3.5 thread, 6mm thread length, 8.5mm overall length - the compact proportions are sized precisely for CMT bearing seat hardware, so the fastener sits flush and does not protrude into the cutting path
- 7mm head diameter - a broad seating surface spreads clamping load across the bearing retainer, protecting both the bearing and the tool body from point-load distortion during use
Why This Product
- Designed as an OEM-specification CMT replacement part, this screw matches the exact thread form, length, and drive type originally used in CMT router bits - eliminating guesswork when ordering a service fastener
- The Torx T15 interface requires a readily available T15 driver, making bearing swaps straightforward in a production shop or jobsite environment without sourcing specialty tooling
- With an M3.5 x 6 thread and 8.5mm overall length, this screw fills a very specific dimensional requirement - having the correct part on hand prevents forced substitutions that can strip threads in precision tooling bodies
- Ordering this fastener under CMT part number 990.077.00 ensures full compatibility with CMT router bits and cutter heads that use T15 Torx bearing retention screws

Frequently Asked Questions
What router bits and tools is this screw compatible with?
This screw is compatible with CMT router bits and cutter heads that use T15 Torx bearing retention screws. It is the correct replacement when the original bearing fastener is lost or damaged during routine maintenance.
What size driver is required to install this screw?
A Torx T15 driver bit or screwdriver is required. The six-point T15 profile is a common size available in most driver bit sets, making it easy to install or remove the screw during bearing service.
What do the dimensions M3.5 x 6 x 8.5mm mean for this fastener?
M3.5 refers to the metric thread diameter (3.5mm), 6mm is the threaded engagement length, and 8.5mm is the total overall length of the screw from tip to top of head. The head diameter is 7mm. These dimensions must match your CMT tooling specification to ensure a secure, properly seated fit.
Is this a thread-cutting or thread-forming screw?
This fastener carries the TBTI designation, which identifies it as a specific thread-forming bearing retention screw designed to engage the pre-existing threads in CMT tool bodies. It is engineered to CMT's specification for use in their bearing seat hardware.
