Damn screw so tight

Some penetrating oils need more time. Some respond really well to a little impact vibration like a light tap from a hammer.
If you had a bit set like this, you could find the correct size and a couple of light strikes might help. The correct size wrench lightly turning on the bit while lightly tapping on the bit with a hammer would simulate the impact driver.
I have those bit sets and wrench, maybe I should let the penetrant sitting a bit longer and tap the bit lightly before using the wrench to turn it.
I will give it a last try tomorrow and then give up if it still doesn't work.

The last key element for dealing with stubborn fastners is confidence and belief that you will get it out of there....
Other then that try and make sure the pistol is as secure as possible in a craddle of some sort so that you can push down hard on the bit and help it resist slipping as you torque.
Some drivers have flat spots on the shank that allow a guy to put a crescent wrench on to the shank to act as a fulcrum allowing more torque to be applied or you could put your hex bit into an apporpriate socket and use a small socket wrench to do the same thing.... Have some faith! Belief in achieving the goal is key....
That Lee Valley Screw grab stuff works great to avoid stripping of the head... not sure where you live but if your in Vancouver they have a couple locations to save on mail order.
I did loose down such a screw on a 1851 NAVY gently using an impact driver. I did make the gun secure in my wood padded vice and just at the first little strike the screw became loose without damaging anything, even the screw.

Princess auto has an impact screwdriver for $22.00. You may have to buy an adapter for it to put Allen key bit on it as the driver only comes with phillips or straight bits probably but they are a handy tool for any small engine repair like motorcycles and stuff.
That wouldn't be my 4th choice for such a tiny screw.... those impact drivers take some skill to use as well inorder to get a nice firm and well aligned hammer shot. One thing for a tradesman, another thing for the average joe/josephine today.
Modern cordless impact drivers were not a thing 20 plus years ago where a guy needed a compressor and air tools.... times have changed.
There is still a place for the hand hammer style impact drivers but they are far from the best option available today for most people.
A 1/4 in drive cordless impact as Can-down talked about , with the power turned down , or just a little pressure on the trigger is great to work penetrating oil into the threads, work both directions , gently, than wait a day, They seem to work good at not breaking stuff, where a straight hard pull with a wrench seems to break sized stuff more.
in the shop I had a 1/4 and a3/8 inch air impact drivers, never broke much stuff with those. The hammer impact driver, never had much luck with that thing.

Like it was mentioned in post #9, watch this Youtube video. Take off the grip.
It is possible the screw was put in with locktite, no amount of penetrating fluid will dissolve that, only heat will.
So, go to Canadian Tire, buy a little Iroda microjet torch and heat up the screw, after that it should come loose no problem.

Right on, I've never seen screw driver impacters, seen light duty "electrician" style cordless drivers but didn't know they made them with impact funtion as well.... golden age of battery powered tools that's for sure!
happy to report I got it off!
I sprayed a good amount of penetrant and let it sit for about 5 hours.
Then I asked my wife to hold the frame using a towel and I turned it with a good grip screwdriver. It came right off.
So lesson learned: penetrant works, and it works slow, and a wife can be used as a vice sometime

Back in the day, impact screwdrivers never had batteries.
The most common type of those days was one that had a tight fitting bit for the slot and you hit the top end with a hammer that was appropriate for the job. There was a helix inside that rotated very slightly when it was forced down by the hammer blow.
It could work in either direction and be used to apply torque as well.
Thanks Bearhunter, I have a heavy duty hammer actuated hammer impact driver...... I just don't refer to it as, or have never heard it called an "impact screw driver" are you saying there are smaller ones as well or are we talking about the same thing?
I've tapped an actual screwdriver with a hammer as I turned it manually though in an attempt to make an impact screwdriver.....
edit, quick search and I see there are indeed smaller versions of the one I have.... got to love it.... never to late to learn something new!

That is what Princess Auto had that I was suggesting. There is some skill involved using them but then I grew up with them.
