Do you need a special tool to attach these?

Yes. This is one, best for things that are not deep into the project. http://www.amazon.com/Dritz-Heavy-Duty-Fastener-Plier/dp/B005BB5GYS/ref=pd_bxgy_ac_text_y If the snaps will be located to far into the project for the plyers to work, then you'll need something like this http://www.amazon.com/General-Tools-1265-Fastener-Fasteners/dp/B00004T7VT/ref=pd_sim_ac_9 You may want some kind of tapered punch set to open up a space for the snap and help guide it into place, especially if you're going through heavier, or multiple layers of fabrics.

No tools are required. You bend them a little and the old ones come off. Do the same for the replacements. Easy.

With the proper screwdriver they are not difficult to attach. You do need to check the current feet often since they tend to fall off after several weeks use if they are not checked and tightened.

They work with a regular drill...but I sent mine back they were not sturdy enough for my need.

yes, you are going to need a ratchet set to assemble this product. Pliers might help, too.

U need to measure the screw holes up with these. And reference the ones on those.

Not natively. You would need to purchase additional attachments to do these tasks.

Remove your existing tips and then put these in their place - takes some wiggling and pressure. Be sure that they are fully on so they will work properly.

Yes. A hex wrench is all that is needed to tighten these on. And, I was amazes on easy they do go on (once the old ones are off). It also makes for easy adjusting out on the road/trail/etc to make sure you get the proper alignment for you.

Usually you do, but it sort of depends how you use them. If they are really tight you'll want to remove them.

you could easily connect them with pliers, just open one of the gold links, attach, and close the link with the pliers. hope you found this helpful

No, not unless you're handy and could somehow fashion a way to attach them together.

Yes. They screw into pre-drilled holes. They must be attached by the purchaser.

Oh no! You're going to need them! If you haven't already contacted the seller, I would try googling them maybe? I, personally, would need them because I am NOT mechanically inclined. Good luck!

No they require assembly. The tool is included. Easy process but directions are not a huge help.

No, I put the ones I have on a fence post and used common horseshoe nails to secure them. Works great.
