How to remove a stripped screw

[agedhorse]

Loose pem nuts can be a pretty tough problem. Fortunately it doesn't happen often. The only solution for this is to cut or drill the head off and the pem will falloff the back side. This screw position won't be useable without some creativity.

Even the smallest one is probably too large for the screws

I'll say again, automatic center punch. Saved my bacon on electronic devices and upto diesel trucks

Remember these? That'll back that screw out for you.

OTOH, it is the only way to remove a JIS phillips screw from an unrestored 70's MIJ bike!
And speaking of JIS, how many of you dinasuars remember Whitworth bolts from the early Triumphs?

And Nortons. And some others like Coventry Triumph automobiles. The really awful ones were from the '70s, when you might have some combination of Whitworth, metric, and who knows what all else. It might be the aftermath of a PO or it might have been the guy on the line just grabbing whatever. It's been a while since I took apart anything like that. Putting it all back together generally meant rationalizing everything so it kinda sorta made sense.

I also remember running away from a Tyrannosaurus that thought I smelled like bacon. Whitworth bolts confused it and helped me get away.

Whitworth? I had a full set of tools that was stolen, luckily after the Austin Healey 100-6 and 3000 were sold.

I like the J'B Weld a nut to the screw head' idea. I've certainly mangled my way thru many a stripped screw over the years and never tried this. However I purchased an impact wrench many years ago when I used to ride a Triumph Bonneville and found myself wrestling with such challenges, which has come in handy for larger screw removals, and have drilled out several small screws, used back out bits, Vice Grips, dremel to cut a new driver slot, and a variety of lubes. It's always a challenge and always frustrating.

Jim, I know you know those good old impact drivers sure did a number on old MIJ bikes, but that's not what you want to use.
This is what you want:
980 Series | Impact | Screwdrivers | Hand Tools | VESSEL TOOLS

The Vessel JIS-compatible drivers also work VERY well in a typical Phillips head fastener. I have a few Maegadora drivers (for the H2 ) that I use anywhere a Phillips is in place

My bike has one Whitworth nut, for the old three speed rear hub.

They sold Whitworth wrenches at Sears at one time.

Thanks Dave.
I've never heard of this tool and the price looks very right.
Thank you for this.
My 1972 H2 is a bit of a special so there are VERY few Phillips screw heads left!

Thanks for the auto punch idea B-String!

I've had the joy of fixing everything from manure spreaders to TV transmitters (ok, some days I'm not so sure their respective outputs are all that different.) Stuck screws have taunted me at every step of the way. I now have a new weapon after all these years. Great big thank you.

 

[Interceptor]

H2. Whoa Nelly.

I rode a RD350 back when they were new. Big fun. I can't wrap my head around handling the thrust a 750cc two stroke had on early 1970's rubber. Way more motor than chassis or brakes or tire. I retired from motorcycles after darn near getting snuffed by a cell phone yakking soccer mom in a minivan a few years ago. The Interceptor handle is a tribute to my all time favorite bike.

 

[Jim C]

Agreed
I've made a few mods to mine
Front brake caliper and M/C off of a modern bike; stock caliper thinned (saved 3 1/2 lbs)
Forks revalved
New rear shocks which are much taller (+ extensions = 15 1/2") with the forks slid through the triple clamps; better weight distribution for the corners and the front wheel stays on the ground at least in the upper gears
Bridgestone tires; modified clutch; updated CDI; Denco chambers; modern headlight; 425 lbs and about 85 HP; etc.
Frame, tank, and much of the motor is stock though
Sounds like no other bike!

I like four wheels, but the drummer rides a H.D. softail, Lead guitar rides rice burners and Keys rides a H.D. hard tail (but he best ride HD as his job is HR with Harley).

Oh, I do! Many frustrating moments trying to figure out why my SAE or metric wrenches wouldn't work on my AJS 18CS or '59 TR6. And then there was British Standard...
