Yoke Screw - What size driver?

[Badger One]

Greetings to all!

I need some help. I would like to remove the cylinders from my 686 and 629 in order to do some deep cleaning. After searching I can't find what size driver to buy for the yoke screws. I want to buy an individual fixed-blade driver from Brownell's just for this purpose. I have no need for a whole set. Thank you in advanced.

Just buy the small set. You may want to take the sideplate off at some point.

Another option is the drivers that accept hex shafted bits. I use those and bring the bits to fit the screws.

Whatever you buy , make sure it's a hollow ground gunsmith blade. If you use a regular straight taper screwdriver and the screw is tight , it's almost guaranteed you'll bugger the screw head.

I have Brownells S&W screwdriver set, place your thumb or finger against the edge of blade and screw head so it wont slide and scratch. If older gun screws could be a little stubborn.

+1 !!! It's dang handy to have in your range bag too.

Or buy a S&W turnscrew

Even if you get hollow ground screwdrivers, be sure the tip goes all the way to the bottom of the slot; most don't in Smith's deep slotted screw heads. If not, extend the hollow grind up the shaft with a small diameter dremel grinding bit.
