Screws break off when assembling into cabinet door. One made an absolute mess of a drawer because I needed to remove the broken screw (without the head). Very upset.
Top Knobs USA followed up on my original poor rating. They are very good to work with. I'm not thinking they manufactured the poor quality screws.

The product itself was not built well. In the hinge part, the screws had cracked the wood. Pretty sure this took maway from the strength of support. Within time anything that would be placed on top of shelf would have fall and break.

I had to return it three times and all three bookcase were the same. All three had cracked wood where the hinge was connected. So the problem was the manufacturer. They should make a pilot hole before screwing the hinge so as to avoid the wood from cracking.

They should look into this and if they do not fix that problem then Amazon shouldn't do business with that company. Avoid hassle that I personally had to go through.

I purchased 2 of these shelves.  After successfully assembling one of them, I opened the other box, and half of the hardware was missing.  I went onto Amazon to try to contact the manufacturer so they could simply send the correct parts, and there was NO response.

Fortunately for me, my husband is extremely handy and after a trip to the hardware store was able to find parts to jimmy-rig the shelf enough so we could assemble it.  However, I would not trust this manufacturer.

I'm not exactly for sure who to blame. It was a Christmas present for my husband. When we opened the box and took it out we noticed two dents in it. While putting it together the screws just fall out because they were pre drilled too big. The bottom door is warped and want hardly shut. I would really like some of my money back or compensated somehow. Someone needs to contact me. My email is mstracydixon@yahoo.com

For everyone who says there's no tool to undo the screws,  it's under the cardboard in the package.  Found out 5 minutes of using Allen wrench,  took a minute with their tool... Thanks for hiding it folks,  you can tell the manufacturer is messing with you when it's the forest thing to fall out when you open the case...

I purchased these screws in this specific size for a 1961 pool table I was restoring.  The professional table mechanics that I paid to set up the table predrilled holes in the wood and still the first two screws they used snapped like twigs.  When I filed for a refund on amazon, the seller questioned if the hole had been predrilled and said "wood screws should never be driven using a power drill".  Really?  These professional installers (and many others) that do construction and use screws for a living are supposed to screw every piece by hand on every project?  Your hardware is weak.  They purchased new screws from their local industrial fastener supplier and they went in and tightened up perfectly.  Avoid this seller's products if at all possible.

One of the screw casings for the floor base was not threaded properly, and we had to use a mallet to hammer it in. Hope we never have to dissemble it.

Be careful when manually inserting in the cartoonishly large screws! The head of these screws are not well put together and will easily pop off if not careful when assembling!

Check rod end mounting plates, drill and tap was of such poor  quality we had to disassemble the whole thing, bolts were so tight they galled on both sides, essentially scrap metal at this point.  Run the bolts in before doing any assy, this could save you a good hour or two and a great deal of frustration.  We shall see if they correct the situation

The screws are so tiny it is impossible to assemble. You should have supplied the tools to achieve this.

The box appeared to be smashed in/dropped/hit. The delivery company was at pains to explain they had not damaged the box themselves. I reluctantly accepted as i didn't want to wait another week. On opening the box-it was evident that someone had already opened it. Nothing appeared damaged apart from box and packaging which had been taped together poorly, but once I started assembly I realized various screws were missing and the owner's manual. Not wanting to totally disassemble everything I proceeded and went to hardware store and bought ALMOST matching screws to those that were missing. It was now obvious someone had cannibalized MY box for screws and instructions (which I STILL cannot find online)! Lesson learned. NEVER ACCEPT A DAMAGED OR BOX THAT LOOKS LIKE IT'S BEEN OPENED!
Any ideas where i can get instructions for the unit WITHOUT someone at Amazon cannibalizing another box I'b be grateful. The only one online did not match the unit I have. I'm really unhappy

The top of my table has raised areas where screws from underneath were put in too tight from the manufacturer

The screws would not go into the bars. I tried for over an hour, even tried screwing them in directly without actually trying to put it together, but they still wouldn't go. After I spent an hour trying, I handed it to my husband and his friend who were also unable to get the screws to work. Now I have to decide whether I want to go through the hassle of returning this giant box, or if it's worth the trip to the hardware store to attempt fixing it.
