4mm wing bolts

I have searched the internet as well as our beloved forums and find almost nothing. So I'm asking for help.

I have several planes that use 4mm bolts to secure the wings to the fuselage. My 3DHS plane has nice wing bolts that turn into place with your fingers. My Extreme Flight Yak has loooong bolts that tighten with a phillips screwdriver, a real pain. My friends have similar set ups .... all are 4mm. If I, or a friend, loses one, well that can stop the flying of that plane. I'm wanting the finger tight style. 3DHS has the plastic ones but out of stock. They also have aluminum bolts that look good, but for 10 bolts it's about 14 $ and shipping is more than that! If I wait for the plastic, I'm sure the shipping will be the same. I found 1 (one!) company that sells what looks to be correct and they won't even tell me the shipping. Guy said that they don't know until UPS picks it up. He said you might get lucky and it's only 10-12 $ ... for 7.98 purchase? Jeez, I feel like a cheapskate, but come on!

So, my friends, what do you know about getting 10-12 of these bolts?

No photo, so I'm not sure if these are exactly what you're looking for:

That looks like what I want. A bit long, but since they are nylon they can be cut, if I need to. I just ordered them.

THANK YOU!

Yes they did. With one very strange exception. In my EF Yak54, the bolts fit into one wing, but not the other. The stock wing bolts interchange from wing to wing, but the new bolts fit only on one side. One is not more "sloppy" fit than the other, so I'm confused. Ideas?
