Yeah, what Cory said. The way I tighten those small, incidental screws around the bike is to use a socket and a screwdriver type driver. Treat it like it was a Philips head screw, 'snug it up' and all will be well without any possibility of over-tightening it IMO.

Yup, I use my 1/4" drive ratchet ALL the time when working on bikes. You will not strip a bolt, or aluminum threads with a 1/4" drive....there's just not enough leverage there, but there's plenty of leverage to get M5, M6, and many M8 sized bolts and screws as tight as they need to be.
Speaking of tools and leverage, during my first job out of college as an industrial tech, many years ago now, I worked for this old guy named Mike. He was close to retirement and had spent two and a half decades in the engine room of an oil tanker that made runs to South America and back. He told me that when they started work in the engine room, all those years before, new mechanics were not allowed to use ratchets for the first whole year of employment...lol. They had to prove themselves worthy with the wrenches before they were able to graduate to ratchets. He used to worry every time he saw one of us working with a ratchet..."You're gonna strip that bolt" he'd say....lol, "why don't you use a wrench". A 1/2" drive ratchet was like the devil's hand to him...lol.
To this day, over 20 years later, I STILL use wrenches way more often than I should.
