I’m using 1 1/8 thick rim board. Because I’m in a high wind location, I need to attach the rim board to the sole plate using A35 Simpson connectors. The shortest MC nail I can find is 1 1/2, which protrudes through the rim. This will eventually interfere with the material covering the rim board, and in the short term, result in a nasty mail sticking out.
Any recommendations on how to attach connectors to 1 1/8 thick rim board?
Update: My engineer and other readers have coalesced on using a 1/2 inch osb spacer. Thanks for all the suggestions.

There are a few potential solutions you could consider:
Use shorter nails: While you mentioned that the shortest metal connector (MC) nails you can find are 1 1/2", there may be shorter ones available online or at specialized hardware stores. For example, Simpson Strong-Tie produces a 1 1/4" MC nail that might work for your application.
Use screws instead of nails: Another option is to use structural screws instead of nails. Screws are available in a wide range of sizes, and Simpson Strong-Tie (the same company that makes A35 connectors) also makes structural screws, like the Simpson Strong-Tie SD Connector screws. Ensure the screws you select are rated for structural applications and are the appropriate length.
Add furring strips: If you can't find shorter nails or don't want to use screws, you could add furring strips to the inside face of the rim board. This would give you extra thickness to nail into without worrying about the nails protruding. Be sure to use an appropriate thickness of furring strip to accommodate your nail length.
Use a different type of connector: Simpson and other companies make a variety of connectors that might work in your application. Depending on the specific conditions of your installation, there might be another connector that can be installed with screws or shorter nails.
Grind or clip the nails: In some cases, you might be able to use the 1 1/2" MC nails and then grind or clip the ends that protrude through the rim board. This would require extra work and might not be practical for a large number of nails.
Remember to always follow local building codes and consult with a structural engineer if needed. The connection of your rim board to the sole plate is an important structural component, and it's critical to get it right for the safety and longevity of your building.
Your last sentence is spam. Why would you ruin the bulk of your post?
Here’s hoping you run out of gas on a lonely road in the middle of the night.
And it’s raining.
I would just add a spacer between the connector and the rim board. The other choice would be to use the 1 1/2" rim board. You could also contact the supplier of the rim board and ask them for a connection design for high wind areas.
