How do you use these ? Drill a hole first ?

It takes some patience, start with the smallest one (remember they're reversible) and slowly working your way up until you find one that grips. They may not seem to grip at first, just keep applying pressure and twisting slowly until they do. I was able to get three stripped laptop hard drive bay screws out after working at them for a while. The first one came out right away but it took many tries to get the other two.

I found them useless. They are supposed to grip after a hole ... but they don't.

They are mainly for laptops (well that's all I use them for), all I had to do was apply a decent amount of pressure and the teeth gripped and the screw came out. I tried w/ pliers and different screwdrivers and this is the only thing that worked.

Ours had no holes also. It doesn't need them, the wood is soft. I didn't even have to pre-drill. I just centered the seat and pushed it tight against the back as I turned it upside down on a table, then screwed it on. They turned out beautiful. Hope this helps!

I had the same problem ,use wood glue and drill New holes or return it .Low quality .I've bought these before with no such problems

Drill hole in wooden post (hole should be just wide enough to place pointy end of anchor inside). Place anchor in hole, pointy end first. Stick wire through hole into pointy end, and pull wire through the other end. Once it goes in the pointy end, it won't go back out, so plan accordingly. Screw anchor to post (holes in square flange). You're done.

I haven't done it but I have seen them with holes. Be sure to use the proper bit and I think you will need to follow the guidelines of drilling glass...keep glass and bit cool.

Drill a hole slightly smaller than the thread diameter, and you should be able to screw them into the drilled hole. If the frame is aluminum it will be easier and the hole can be a little smaller so the threads will get a good grip on the soft aluminum.

Go to some of the sites that offer these for sale. Some of them list the installation instructions and that will tell you if you need to drill holes

No they do not have predrilled holes = use a bit for your drill and just press a little - the screws are self drilling / tapping screws.

yes you need to drill holes first but match the drill bit to the size rivet you want to use

Here's a video tutorial on how to use them: http://m.youtube.com/watch?v=yGuAudd4FGs

simply drill matching holes in the correct size needed. most hardware stores should have short pieces of flat stock ,in many sizes. re use the same screws.

Use the lag screws (the ones with the large threads) and drill them directly into two studs (drill a pilot hole first).

Those should be driven out with a roll pin punch. These are not in too tight so a nail that is ground flat on the end could do the job. Good luck

I used a 3/8" bit for the through holes in the beam. The bolts are 3/8" so you have to tap them through with a hammer. I recommend that you use a drill with a built in bubble level in order to get a straight hole. That's a pretty long hole to drill by eye. Also you may have to do a lot of sanding on the 4x4's and 4x6 in order to get them into the brackets. Lumber dimensions vary even within each piece. I uses a 5" orbital sander and it still took a while. Good luck!

You are going to have to use a hand saw or a drill to make the holes. There are instructions in the box on how to figure the dimensions.

Drill a hole with a concrete drill bit. Place a plastic anchor in the hole. I used one sold for sheet rock use and tapped it into the hole. I made sure the size of the anchor fit with the screws that came with the shade. Works really well.

With the drill, I would recommend pilot holes. If you get the impact wrench, no need for pilot holes.
