When you just wanna screw

[fencer]

To come out but the damn thing is stripping its head and not breaking loose despite copious amounts of lube

Trying to move my Givi mounting bracket between the bikes...

[Festus]

Smack the head sharply once with a hammer or a flat punch/hammer.

[fencer]

I am happy to report that with enough penetrating fluid, a little more patience (started last night ), hitting just the right angle with just the right amount of pressure....
I have accomplished a successfull reverse screw.

This sounds like a line from a poorly written erotic novel... or so I’ve been told.

Fencer,

Yep, RaYzerman has the key. Insert the bit, twist the handle in the direction you want (counterclockwise, this time), and smack the end of the handle smartly with a hammer. This process drives the bit solidly into the screw, and give the head a little twist. One of the best bike tools you can own. There are impact driver kits almost anywhere that sells tools, and here is just one:

How well do those work when the head has been damaged? You need a special bit when the head is wollered out?

So THAT'S how they work. I've had one for decades and never could find anyone who could tell me which direction to load it before smacking it. I've showed it to 10 people and they puzzled it over because there are no markings on it and no instructions.

DanH,

It helps to start with the right tools. Yamahas do not use Phillips screwdriver heads, or anything "similar." Yamaha uses only JIS (Japanese Industrial Standard) screwdriver heads, as their cross-pointed standard. If the screw is really butchered, JIS bits might still do the job, but you may be asking too much, in some cases. An impact driver really helps then, of course. JIS bits may look like a Phillips, but using a Phillips tool can cause you grief. Here is a set of JIS bits, although you can get them from many other sources, like McMasters-Carr:

I put paint dots on my JIS bits, so I won't be using them on Phillips heads, or vice versa.

Butt sore?

Impact drivers are lefty loosey, righty tighty. Turn and spring load it in the direction you chose (I don't use them for tightening usually), then smack it. Smack it again if you need to. Keep it engaged in the screw recess.... an impact driver may bail you out if the screw recess is slightly damaged... once you've rounded it out, you're looking for a drill...... you can drill a slightly too small recess for a Torx bit and slip it into the impact driver, kinda cuts its own recess, but hopefully you don't have to go that far.... it might work, it might not.
Phillips bit may damage a JIS, you can fake a JIS mostly by grinding a tad of the end of a Phillips bit to let it seat deeper, but nothing like the real thing. Once you have JIS bits, you can toss all your Phillips as they will work on Phillips..... BUT, JIS bits are pricey sometimes so save them for the good stuff...

Simple way of getting it working in the right direction. Insert the tool into the fastener and rap firmly... okay twice or three times. Check the fastener. Is the fastener now a half inch further into the hole? Yes..., then reverse the tool.

Riders,

High irony there, and yeah, Pterodactyl makes a good point. If you use an impact driver to tighten a screw, only an impact driver can remove that screw later. I once had a Yamaha dealer who did that routinely, to keep his customers dependent on his shop - nobody could disassemble anything that they had "serviced." That was when I bought my first-ever impact driver. if you are using an impact driver to tighten a screw, it is far too easy to tighten a screw enough that you will either shear off the head, or strip threads. D.A.M.H.I.K.

I do not recommend using an impact driver to install any screw, unless you are planning to seriously mess with the next poor dude who tries to remove that screw.

^^^^^ Just 2 weeks ago before I left for Arky, one of our secretaries went out to her SUV and noticed it had a flat tire. So I jumped into action. I only live 0.9 miles away from school and we all know how much we hate Car compact jacks; Especially on uneven gravel, so I went to grab my floor jack/real tools.

The afternoon custodian came out as I got back and proclaimed he could not get the lugs off. He was right. After we jacked up the car just a little, we tried breaking loose the first nut. Nope. Not budging. Idea—- take the jack handle off and use that as a cheater bar with the tire iron on the nut. Promptly bent the tire iron slightly with the 3 foot lever. We only salvaged the job by inserting the whole handle of the tire iron into the jack handle.

I am not nearly as strong as I used to be, but currently am not exceptionally puny. But damn, whoever put those lugs on did so with an impact wrench set right next to snap the heads off. Pushing down on the bar was not successful. I had to actually pull up on it at about 3 feet of leverage. Some math person here can offer their estimate on foot pounds more accurately than I could. If I had to guess, it was slightly more than 9.274 Holy Shit tons per metric mile of hernia popping force.

Ms. Rosie was estatic we were able to help and got us Subway the next day I offered her just one bit of advice to tell the dealership. Go easy on the impact wrench or stop using loc tight. She told me the next day “Mr. Cav, they said they do not use loc tight on lug nuts ever, but always use a impact gun to keep people from trying to change tires on their own”. What the heck??

Ms Rosie is the sweetest person ever, and I forgot she is a literal person. I never actually intended for her ask that question........but she did.

^^ This is why I have always carried an extra T-handle lug wrench and an extra jack. You never know when pressure and leverage isn't good enough. I put the second jack under the straight out arm of the wrench to hold it up so I can stomp on one of the perpendicular arms. Like using an impact, sometimes the sudden shock is needed rather than immense steady pressure.

[wheatonFJR]

Cav, I think you need a few more significant digits in your shit-ton torque value, but I understand you were just rounding this off.

That mechanic is an asshole.

[bungie4]

I put all 4 of my snows on yesterday. I'm unemployed, time i have, money not so much.

Stupid rims were seized onto the hubs on three of them. A little blast of penetrating oil and a whack with a sledge, no more seizey. Only one put up a fight. Figures it had to be the first one.
