bought this tool to install security bars on my windows, Unique one way screw driver stripped out on first screw. would not even grip enough to start second screw and started to strip screw head. This tool was completely useless and definitely not worth $15.75 I paid for it. needless to say I returned it for a refund, it's the only one Home Depot carries and you can only buy it on line. I would not suggest this tool to anyone, save your money and find a better one else where.
I cannot give a personal opinion for this product as I did not use it. The size was too large for my needs. The description did not say that it was sized for screen door or gate. I needed it for a one way screw on a inside door lock. I wish I knew where to return it. Please feel free to let me know this information.
Evey tool has techniques and rules for safe and succesful operation. This driver is no exception.The one-way lag bolts used to mount security doors are just that. A bolt, not a wood screw. A wood screw has an ever increasing diameter on the threads. A bolt is usually the same dimension all along the shank. The instruction on the package tells part of the secret: "PRE DRILL HOLES FOR BEST RESULTS". The reason you are doing that is because you are probably trying to mount your security door on old wood, which is dry and will split if you try to drive all the lag-screw diameter into it and it won't give like new wood will. The pilot hole should be the same size as the inside diameter of the threads shank. It is only the outer threads that do the gripping. Then an old carpenters trick: Get a regular hex-head lag-bolt of the same diameter and length as your one-way lag-screws. Apply some wax (Candle, Beeswax, etc.or oil)to to the front of the lag bolt. Use your drill motor with an adapter and a socket to drive the lag bolt into the wood and then remove it. You have essentially "Tapped" threads in the wood with the hex-head lag bolt. When you screw the one-way lag bolts in use a lot of pressure and push on the drill motor so the driver does not jump. Control the speed of the driver so that you don't try to ram it in like you are used to doing with wood screws. That way when the head of the lag screw seats against the surface you don't have the driver bounicing off of the one-way lag bolt head. That bouncing is what tears the driver up. Didn't take me multiple trips. Installed my security door and the one-way screw driver is just like new! Great tool!
Poor drill bit design. bit easily stripped. need to go exchange drill bit, so security door can be finished mounting! Two more screws on upper bracket still not in place. all side screws were stripped, had to go to Home depot to purchase additional screws from door installation! not recommended product
In the past Ive had to cut the screws off at the head in order to get security doors/bars off and then had to purchase new one way screws to reinstall the security door/bars. This tool enables you to remove those screws. Considering that often times the security door/bars get damaged in the process of cutting the screws off, this tool saves time and money.
Pros: Durable, Easy to Use, All In One, Sturdy, Accurate, Strong, Good Size & Weight, Light Weight, Long-Lasting
I bought this to use while installing window bars that require one-way screws. This driver worked on about 3 screws before it began stripping. It's not a good design and requires you to apply a lot of force against the rear of the drill in order for it to stay seated in the grooves of the one-way screws.
You are much better off using a large flat head screwdriver to install one-way screws instead. That's what I did after this thing broke and it worked 100% better. Don't waste your money on this.
The tool was used for installing one way screws in pre-drilled 1/4 inch diameter holes for a security door in a house was built in the early 1900's with very hard & dense virgin timber. The tool would frequently slip off the screw head and the spring loaded collar that was supposed to keep the tool firmly on would slip off of the screw head. The worst part is the hardness of the tool head is softer than the material of the screw head. Therefore when the tool slips off of the screw head, there would be damage made to both the tool head and screw head. The rounded edges of the tool and the rounded edges of the screw head make for a difficult installation.
The type of one-way screws used by the Unique Home Designs products are best installed by a large size slotted screw driver. This type of tool is primarily used to remove them, which it does poorly. I use stainless #14 pin style Torx security screws. With a correctly sized pilot hole, the driver bit for these screws never strips or slips. Essential if installing security bars that must be periodically removed to install screens or otherwise service the window..
When I first received the product, I said to myself, "Self, this looks cheap." I was correct (unfortunately this isn't reflected in the pricing). In order to use the 1/4" chuck in my 1/4" Makita impact (18V), I had to use a die grinder to reduce the size to a true 1/4". The alloy used is so soft that the teeth are ground down in no time flat, which is primarily due to the fact that the driver slips off of the screw's head nearly 90% of the time and often violently (ruining a door's finish). You literally have to use all of your body weight to hold it on the screw head (in my case 175lbs) to avoid slippage. I'm also still unsure why they call this a remover, because it comes nowhere near removing a one-way screw. Heck, it can't even drive them in effectively. Please, I implore you... do not buy this product. Use the money instead to go buy hex-head lag-bolts and use a socket set to install the door. One-way screws are a gimmick. No one is going to bring a socket set with them to rob your house.
Your better off just getting normal lag screws or bolts and the than rounding the head off with a file because this 15.00 driver is garbage.... and you should use at least a 1/4 in pilot hole and not the recommended 3/16.... I would like to get my money back.
This bit will drive in the oneway screws but slips around the head of the screw. While trying to remove the oneway screw, the sleeve does not keep the bit from slipping around because it is spring loaded and does not lock into place and the bit does not grip the head of the screw.
I went through four of these installing two doors. Good concept, cheap material. What should have been an hour job per door turned into a weekend of 10 mile round trips to return and get new ones. If your door doesn't come with the bit as some do and some don't, spend the extra money and get a good tool.
