Product Description
CMT 990.087.00 Screw for Bearing STEI Pin M6 x 8mm is a precision replacement fastener from CMT, engineered to secure bearings on router bits and cutter heads. This STEI-style M6 x 8mm screw provides the exact threading and head geometry needed to keep bearings firmly positioned during routing operations, helping maintain cut accuracy and extending the working life of your tooling investment.
Key Features
- STEI Pin design in M6 x 8mm size - matches the precise thread pitch and length specification required for proper bearing retention, eliminating guesswork when sourcing a replacement fastener.
- Engineered for bearing retention on router bits and cutter heads - keeps the bearing locked in its correct position during cuts, preventing lateral movement that could cause poor edge quality or premature tool wear.
- CMT original replacement part (MPN: 990.087.00) - ensures a factory-correct fit with CMT tooling, so you avoid compatibility issues that can arise with generic alternatives.
Why This Product
- A single loose or damaged bearing screw can render a router bit unusable - this factory replacement restores the bit to proper working condition without the cost of replacing the entire tool assembly.
- The M6 x 8mm STEI Pin specification is an exact match for compatible CMT router bits and cutter heads, meaning the screw seats fully and torques correctly the first time.
- Keeping a spare bearing retention screw on hand reduces downtime on the job - a small part that is easy to misplace or strip during routine maintenance is now readily available as a standalone item.
- The active production status of part 990.087.00 means this is a currently manufactured component, not a discontinued item, so it is appropriate for ongoing maintenance programs.
