MAP sensor bolt spec - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

A few years ago I swapped my 2015 plastic intake manifold with the wrinkle red one from 2017+ and reused the original bolt. It wasnt an exact fit but kept the map sensor in place so I didnt fret over it. Now I am upgraded to a 4 bar and upping my boost so I want to get the correct bolt. See below for clarification

im sure I can pick something up at the hardware store just cant find measurements anywhere online

My 2018 appears to use a coarse M5x15 flanged bolt with an un-threaded shoulder about 2.5 mm long at the base and an 8mm head. It doesn't look like the shoulder part is critical - it is narrower than the threads (vs. more typical shoulders where they are in the outer diameter of the thread) so couldn't be used for locating the bolt on the sensor.
