Can anyone offer suggestions on removal. Mine are installed so tight head is stripping and screw not coming loose....thanks in advance!
JIS - Japanese Industrial StandardOh, ok I didn't know that had a name thanks.
Not that it matters, but it's my contention the issue is not the factory over tightening the screw.
I think the issue is the fastener or the threads in the frame are corroding a little and causing the screw to be stuck.
The solution is to buy a KRX.
Not really, smack the screw with a hammer to break it free.
I use a small punch (not usually effective) or one of those cheap interchangeable blades on a single screw driver handle things (I think it was a gift from my mom).
Drop the plus driver in to the screw, smack the other end with a hammer.
However, the thing that @Hondasxs suggested also works.
Impact driver is my last chance before I break out the gas axe (cutting torch).
When you reinstall any screws apply anti seize to the treads. (this step relates to my corrosion theory above)
A good friend of mine (John Doe #2) sed he has seen that HODOR now installs those screws with green sleeve retainer lock-tite since the conclusion of Game of Thrones series. Rumor has it The Hound then QC double checks for proper tightness of 157ft lbs by using only his thumb and index fingers.
So rumor has it, the QC guy puts a torque wrench on the fastener and feels for a click.
Paint mark the screw and kick it down the line.
Wheather the screw turns or not has no bearing on its ability to be paint marked.
(But I still think the plus slots would be stripped out if they where tightened that much on the line)
