Senton T-Bone rear bumper screws fell out - NEED SIZE

[Mr.Vylan]

I purchased the front and rear T-Bone bumpers for my Senton 4x4 3S BLX.

I notice today the rear bumper was loose. It turns out the two screws shown in the attached photo were missing. I need the size of these screws, and hopefully where I can purchase them.
I'm assuming it is this style --> BUTTON HEAD HEX MACHINE SCREW

Yes they are button head and I am assuming they are m3 like the kraton front bumper. I am not sure on the length.

M3, okay... maybe 10mm long? I'll measure the depth of the two pieces of plastic.
I was thinking they might be M4 as the diameter seems like the bigger of the two sizes used throughout the various parts of the Senton.

I'm not positive I don't own a Senton But I know they are button heads for sure, and for the kraton atleast they are m3 or the smaller diameter screws,.

My brother and I have the same bumper in our Senton and we both lost the same screws after a bash session. Those screws were M4. However, replacing the screw didn’t fix the issue because the brace got stripped. We ended up using a flat head screw in the chassis side and secure it with a nut on the outer side.

You can use whatever head you want. I prefer socket head screws where I can use them. They usually use a larger hex, meaning less stripped heads. You don’t want to use them on exposed under sides, where they can snag, but anywhere else you would use a pan head, you can usually use a socket head. ??

Perfect solution. I'm going to do that. It's a bit of an odd design since it seems like it can either be a single unit or at minimum not use a short screw to fasten.
