Front action screw size?

What size is this head? I tried every bit in my gunsmith toolkit and every allen wrench in my toolbox and NOTHING fits.

Figured out its between a 3 and 4mm, so no idea where I'll find a 3.5mm wrench. I just used a Torx bit instead that just happened to fit :)

Does your kit include any fractional sizes?

If it's a stock Savage screw, it's 5/32.
