Rated 4.9 out of 5 by 7 reviewers.
Rated 5.0 out of 5.0 by Can't believe you discontinued! This is one of the most useful products in your whole store! REALLY you discontinued...how much space did it take up? A few inches..Very disappointed. March 22, 2016
Rated 5.0 out of 5.0 by Home Depot disappoints . I understand that many products do not sell in a Big box store like Home Depot. But this product was and still is amazing and it should have been marketed differently and I assure you it would have sold a pack with every door. The employees were unaware of its potential and worse yet its existence. I hold the Home Depot responsible for poor marketing and a lack of trained personnel to lead home owners and contractors to the right tools and materials for a project. These screws are incredible and dummy proof. I will have to find a new supplier. June 11, 2015
Rated 4.0 out of 5.0 by pretty good As the other reviewers write, these make installation and adjustment easy. However: the material of the screw itself is soft, and if you ever need to back them out completely it will likely strip, or the outer screw will detach from the inner (both happened to me). Also, you need a half-inch hole which has to be covered or plugged -- making later adjustment a bit more awkward (although you could just leave a small hole to access the inner screw). So: nice design, but I wish the material was harder and the price lower. December 5, 2014
Rated 5.0 out of 5.0 by Where have these been all my life???!!?? Nothing in the money pit of an old house we're restoring is plumb, square or level--20 years of shimming, planing, scribing to fit, etc. This past week we've gotten stuck on a project that was about to do us in. Out of desperation, we decided to look these up, having seen them yrs ago on This Old House. Problem solved in less than 10 minutes! That includes reading directions, drilling holes, screwing them in and adjusting. We're amazed. Totally worth the money, even with having to buy the specialty driver. December 18, 2014
Rated 5.0 out of 5.0 by This product rocks! We replaced a couple of doors in our house that sat inside of some pretty scary openings and this product allowed for super easy adjustment and the door hang perfectly. I would pay double the price for these screws - they make door installation that easy. No shimming, no driving/re-driving screws - just remove the weather stripping, drill the 5/16" hole, pop a screw in and you're ready to start making final adjustments. Highly recommend!

Rated 5.0 out of 5.0 by Good product, but expensive I have used these screws on several doors and they work great. They take the place of shims and make adjusting or readjusting a door frame much less difficult. I use 8 screws for a standard door jamb; 2 at the top header and 3 on each side. This allows me to level and plumb both sides of the jamb. The down side is each door costs about $20 for the screws. I would have expected Home Depot to have better pricing on the screws or at least a bulk price, but their price is retail. September 20, 2011
Rated 5.0 out of 5.0 by shim screws Have used the product before and it is very easy to install with the tool made for it. It solves the trouble of using wooden shims when installing a door. It is very useful when your door swells from humidity by just using the installation tool to adjust the door jam in or out to maintain the proper gap. Used to be able to buy these in the store but now have to order online. April 30, 2011
