    I don’t have a spare at my house and I’m wondering what size / # screw fits in the mounting hole. I want to order weld mounts tonight and am not near the boat. Any help is appreciated. Thank you!

    All of the tees can be mounted with #8's 8x1-1/2 the tees are not universal in there depth and range from 3/4" to 1" thick. I also use Anchor exclusively at this point, https://www.ancorproducts.com/en/products/Wire-and-Cable/NMEA-2000 .

    I use to use Garmin but there tees are soft and actually break internally. Anchor has a great product line and tougher, thicker cables. Also all tee's are not created equal, they are keyed and one manufacturer does NOT line up with the next one. The Anchor ones can be had off of Amazon https://www.amazon.com/Ancor-Marine...=1660687172&sprefix=nmea+2000+,aps,135&sr=8-3

    Also Garmin, Maretron, and Anchor clock differently when they are put together making it impossible to mount as an assembly. If you are going to have more than two co-located, consider a 4-way; it is so much more compact and fault proof. This is mine for the helm leg.

    Besides the fact the 4 way Tee is more compact, as Tom said, much more fault proof. Stringing along the individual Tees can add stress to the connector if not well supported.
