2TR-FE MAF Sensor screw part number?

Long-time lurker, first time poster... hello!

I was cleaning the MAF on my 2012 Tacoma with the 2.7l 2TR-FE engine and I’m embarrassed to say I dropped one of the two screws holding the sensor - it's now somewhere in the engine bay and I can't for the life of me find it.

The screws are -not- machine screws/bolts but the type that are “thread forming” for plastic. They in fact have a cutting thread that’s of uneven diameter - 3.87 mm diameter at its thickest and 10.22mm long, with a "washer head".

You can see an example in this MAF cleaning thread (https://www.tacomaworld.com/threads/2tr-fe-maf-sensor-throttle-body-cleaning.262717/) on page 2:



In most circumstances I’d be fine putting in a similar screw and calling it good, but this part needs to be properly sealed and if I use a screw with different thread - even the right diameter - it’s not going to hold up to cleaning over the years and I'd have to replace the whole air filter box.

Does anyone know the Toyota part number for these exact screws? I found a few possibilities but none that I could confirm are exact for this year and trim. Any help is much appreciated!

 

Amazing! This looks to be exactly it. Thank you so much!
