Hi !

Sometimes sh@t happens, even in the middle-east.

I screw the screw so hard that I removed/severed the screw head in the process. Now, the bottom of the screw is still attached to the fin, but I can't remove the screw because the screw head is gone. Basically, if I can't change the fin if broken, I have to throw the board.

That looks like a Tuttle box, remove the screw in front of the one the head popped on. Once the front screw is removed, then remove the fin, grab the broken bolt with a pair of pliers and unscrew from the fin. Find a replacement bolt and re-install. Simple.

Hi !

I have done it, but the screw is till stuck in the fin.

I will put the whole thing in soap water to ease the unscrewing process.

Double serving of kebab for everyone if it works tomorrow.

Stay tuned. This is the most thrilling event of the week.

If you can't get enough grip with a pair of standard pliers, Vice-Grip locking pliers will allow you to clamp on that screw and turn it out easily. If you don't have a pair, they are very much worth buying ... A terrifically useful and inexpensive tool.

Just a comment- you should not need to be tightening the fin screws anywhere near hard enough to snap the heads off. On a Tuttle box, all the screws do is hold the fin up flush with the bottom of the board, the box itself is what takes all the load and the taper at the front and rear of the fin head is what determines how well the fin fits in the box. If you are trying to tighten the screws to get the the fin pulled up all the way into the box, then you need to take some sand paper and remove material from either the front or back of the fin head until the fin fits properly. The base of the fin should be about 1/16" proud of the bottom of the board when it's just dropped in the box. Then the screws should be installed finger tight and then given maybe a half to one full turn just to snug them up and pull the fin in that 1/16" so it's flush. The screws do not need to be (i.e. should not be) cranked down. Tuttle box fins almost always need to be custom fit to the board in order to fit properly, so if you're cranking down the screws to get the fin to fit properly, stop- take some time and adjust the fit of the fin.

The other issue would be if you're using english screws with metric inserts (or vice-versa). A 1/4"-20 screw may fit into a 6mm insert, but it will bind. Make sure the screws you're using are compatible with the inserts and make sure your fin is properly fitted to the fin box and you'll save yourself a lot of hassle.

Yvan,

My local dealer strongly advised me against using hexagonal socket head screws (even if Bic uses those). He said he has seen cracked fin wells caused by the extra torque we can apply on those. Better to use Phillips screws that are harder to torque.

If you were using a wrench to set your hex srews, you'd better look for fine cracks in you fin well.

Excellent advice sm. However, it could be that yvanboniec may be using screws that are a bit too long. If he bottoms the screw out in the barrelnut with the fin base too proud in the box and over tightens it with a socket wrench, the head breaks off. What works best is to have the fin screws custom fit to the board.
