I use 1/4, 11/32, 3/8, and a 1/4” ignition wrench. Make sure they are all deep socket so you can get to the unlock nuts on the long studs. Basically they are hollow shaft.

The nut drivers I use a lot : 3/16, 7/32, 5/16, 11/32, 3/8, and 7/16. I have sets of them in metric and standard. Also deep well sockets for any long studs you can't get a nut driver over, 1/4 drive, 3/8ths, and 1/2 inch - both metric and standard.

I have 3/16, 1/4, 5/16, 11/32, 3/8, 7/16 and 1/2" hollow shaft. Then I have a 1/4, 5/16 and 11/32" long shaft magnetic nut driver. Also a set of ignition wrenches both open and box.

Great thread I have been pondering this myself, I did want to add one further question. What length do you guys like? Is six inch two long to maneuver or three inch too short to get at things under a pin? Is the obvious answer have both?

Been using these Harbor Freight ones for years, they come with a stand, too -

I dont think a 3in would be very handy, most everything on the bottom of the pf you'll be trying to get in between other stuff.....

You will need 2 sets.

A set of full hollow shaft nut drivers and a set of magnetic.

The hollow shafts at harbor freight are terrible, dont bother.

Get the husky ones in a pinch or the craftsman hollow shaft drivers.

And get a set of Klein magnetics with the long shafts.

A 5/16" x 1/4" multi driver is good for posts as the full shank is 5/16" and will go over mini posts on the 1/4" end.

I use 3" Klein. They are hollow shaft, so they work fine with thrubies.

For the longer stuff under the playfield I use a Black & Decker driver with an extension and 1/4 and 5/16 sockets. I have two 6" extensions, so it is very rare I can't get to what I need. I also like using the driver because if something strips with it, I'd rather have it happen while I'm working on it rather than while playing.

Finally for the metal playfield posts I use a Tekton 1/4" drive deep socket set.

I realize that is a lot of stuff, and I could do it with less. But the versatility I gain is worth it. For stripping down the top of a playfield, for the most part I'll use the Klein drivers. For under, I'll use the power driver with the extension to get them. And for specialty stuff, the sockets.

The Klein hollow shaft walls are not thin enough.
I rarely use mine any more, they wont go over a lot of bolts and are useless for posts..

The cheaper full shank thin wall hollow shafts are whats needed. They have to be hollow all the way thru.

Huskys are ok for the most part.

But I use my Klein long shaft magnetcs mostly as well.

The pittsburg ones are useless.

In a pinch you can drill out a hollow shank nut driver to get the wall thinner. I have had to do this a few times.

The ones I use most are Klein long shaft 1/4", 5/16", and 11/32".

I picked up two sets from Titan Pinball, one for the games, one for the shop.

Klein long-shaft hollow magnetic are great, but be prepared to swear the first time one of the magnets pops out and stays on the post you just tightened.

I wasn’t fully awake when it first happened and it took me a minute to realize WTF was going on.

Definitely get magnetic, dropping screws and nuts sucks. Also, get one of those magnetic grabbers on extension pole. You won't regret it.

I put a little drop of epoxy on one of my Klein nut drivers magnets.

Its held ok for a couple years now.

I like the klien set too, but tend to use my non magnetic craftsmen set.

I would like to see wiha tools make a magnetic nut driver set, myself.

Now I went and looked!

Any ideas for driving mini-posts? Hollow drivers and deep sockets will not work. At least not the various tools I've tried. There must be a better way than using a wrench. Thoughts and thanks.

This works well. Just remove the driver bit. The shaft is completely hollow.
