These are something that FastTech does indeed carry but I don't know what size. Sorry.
You can measure them.
First the diameter. That's likely M2.5. If so, your measurement will be just slightly smaller than 2.5mm.
Next measure the length. Since these don't have heads, you measure the whole screw in mm. It might be 3mm.
So it's probably something like M2.5*3mm
SKU 3981606 (Just a guess. Measure to be sure.) If it's a different size, find it in the dropdown list.
