Having a ball today out at Dog beach booooooosting!!!!(hero) - stacked a jump and was dragged...(noob)
What resulted was the side of one strap getting pulled of my board. The two stainless screws failed.
The problem I'm facing now is the bolts joining the straps to the twin tip are not stainless and have rusted.....I cant undo the bolts joining one to the other....
has anyone had this problem or recommend a solution?
I have tried wd40, they are lock tight!
Some awesome rep want to give me a cheep board? Your company logo would look great 30 foot in the air. 
In order of frustration:
Penetrene/PBBlaster and let it soak overnight
use the correct size screwdriver applying loads of force downwards
Try tightening it slightly as well as loosening it
Judicious taps with a hammer on the end of the screwdriver as you try to undo it
Dremel the head so that you can get a flat screwdriver into it
More Penetrene
Dremel the head off so you can get the strap off
Apply heat to the thread
Vice grips on the thread, closely followed by...
Snap the rest of the thread off flush with the bolt
Swear loudly
Dremel the rest of the thread flat so you can then...
Drill a small hole through the bolt
Ezy-out
Snap the ezy-out
Cut the kn nut out altogether and glass a new one in
^^^ Gold. Words that can only come through bitter experience.
So learn from the mistakes of others and let the penetrene soak for a few days. During this time give the heads of the screws some light taps, vertically and from all sides using a punch to access them. Definitely try loosening and tightening them. Anything to get the slightest bit of movement, then more penetrene. If a few days of this doesn't work then don't stuff about with ezy-outs, just grind/drill the heads off the screws, pull the straps off, grind the screws down to the board and put your new straps on in the adjacent set of inserts.
I've seen tall guys using narrowest stances and short guys using widest settings so you can easily get used to a slightly wider/narrower stance.
Use a cordless impact drill/driver,works a treat you can get the perfect amount of downward force and can give the screw a few zaps in both directions to free it up,have pulled out badly cross treaded and rusty screws with one of these.
Hi Underoath,
An easier fix is to simply drill out the old bolt with a 4.5mm drill bit. Make sure you drill it dead centre and keep the drill perpendicular to the board. Be careful and take your time. You want to drill out the bolt body to the diameter of the valleys (narrowest width between the thread pitch in the screw.
Once you drill it out, get yourself an M6 intermediate tap and slowly, using penetrene, tap out the rusty thread which will be stuck in the helicoil insert. The insert should be fine as it is hardened steel and wont cut from the tap, the soft steel screw will give and align the tap with the thread and you can then clean the insert with a finishing or bottoming tap to complete the job.
Go slow and advance a quarter turn, then back the tap out 1/2 a turn before advancing another 1/4 turn <repeat>

See your mate with a welder. Place an 8 mm nut on top of the srew head, 1 spot weld. Apply spanner. Done.
I had the same problem when trying to change my straps - I cut the straps away, then applied WD40 to the screw, then turned the board upside down and clamped the screw in a bench vice. Crank it up nice and hard, then spin the board around the screw. Worked for me and I didn't tear the inserts.
TIP: Be very carefull not to apply too much heat otherwise you may find the insert starting to spin in the core of the board when trying to remove the busted piece of crew from the board. Go easy and carefully is the way to go, if drilling file the remaining bit of screw flat first and centre punch then drill a little bit at a time, don't rush for the best result.
Good luck
