Effective 30-Jun-2023 at 12:01 am PT, the six mounting holes/screws in the MK4i Swerve Module for attaching it to the drivetrain frame will change from using 8-32 screws to 10-32 screws. Details:
The change enables the swerve module to be directly mounted to commonly available 2' x 1" aluminum tubing with pre-drilled 10-32 clearance holes (example: MAXTube).
If ordering a replacement/spare Screw Kit, be sure to check your existing MK4i Swerve Module for what size frame mounting holes it has to ensure you select the correct kit variant to order. If your swerve module was ordered before the above effectivity date/time, it likely has 8-32 holes. It otherwise likely has 10-32 holes (check to confirm).
The kit will include either of the following depending on the Frame Mounting Holes variant selected:
10-32: Screw, 10-32 x 2-1/2 Cap (Quantity: 6)
8-32: Screw, 8-32 x 2-1/2 Cap (Quantity: 6)
