Hi there is aclip on you tube changing a stock on a tikka t3 and I am sure he says what size they are.
It's what came in the box and it worked on my old T3....I'm not sure that TIKKA tool looks quite right, but here's the YouTube link ......
Which says that earlier T3's are conventional slotted (blade screwdriver - as in the M595/M695 series) and later models (American spec.) are TORX T25.
I've never seen the point in adjusting the trigger pulls on Tikka rifles, which share the same assembly as the Sako 75 & 85 series. I have more than a few Tikka's, all of which have wooden stocks & blued barrels with not a T3 amongst them thankfully.
Triggerwise, all mine are identical so I've never thought about tinkering with them. The factory-set pull is the perfect weight, and breaks smoothly.
Never taken them apart, or even disassembled the bolt for cleaning. Amateur gunsmiths should leave well enough alone IMHO.
