Insta-back 1/2 Inch Drywall Fastner Clip Plumbers DIY 50 Pack with 100 Screws Instaback

Really ingenious product. I used to glue a little piece of wood behind the sheetrock, and then reinforce it with screws. This product makes fixing big holes in the drywall faster.

Practical and easy for repIrs

No instructions provided, needs some improvement for DIYers. I had first used an impact driver assuming these were intended for use with both drywall and studs. Turns out an impact driver just bounces and destroys the drywall, especially on a ceiling application due to the the difference in how a drill with a screw adapter vs driver works. Got it working with a plain old screwdriver. Moved to the drill and it worked fine. I assume you have to predrill into studs since the impact driver won't work.

Great patching wallboard

I had a large rectangular hole in the wall behind my bathtub. I was not aware of the Prest-On Insta-back 1/2 Inch Drywall Fastener until I saw them on Amazon. I watched the short video showing how to use them. Because of the limited room between the tub and the wall, their use saved me considerable time. The went in easily. The retainer hooks snapped off perfectly. With the addition of patching tape and a few coatings of mud, I was able to accomplish a sturdy repair. For the money, I have enough fasteners for several more repairs. Oh, and they came with just the right size drywall screws.

I work in a high rise building and these are a must have

This is my second time to use these. They work great

These fasteners were used for drywall repair in a home-wide repiping project. The drywall pieces had to be slightly notched to accommodate the thickness of the clip around the drywall. So putting up with that inconvenience made them less than ideal.
