Work much better than a Phillips head screw

Work much better than a Phillips head screw, but not as well as a "Starhead" screw.  It's still possible to strip the heads by rounding it out.  A Starheaded screw won't do this.

Use the screws provided, and they work. Cheap, simple, and effective!

Flat head screws and lock nuts. They are what they are, and they work just fine. No problems. Hard to find these sizes in the local hardware stores for some reason (?).

OK, except the screws included in the package are dead-soft. Although I pre-drilled holes into the wood, the Phillips heads stripped out way too easily. Some 1.5" long #10 sheet metal screws from Home Depot did the trick. Also, the instructions were unclear about pre-drilling for both the screws (provided) & the lag bolts (not provided).

Phillips heads aren't very sturdy, using square drive is better but still not as strong as some other screws I have used

I first bought these screws in the 3 1/2 inch length. I liked them so much I bought several other lengths to have on hand for projects that may pop up. Below I attached my review for the 3 1/2 inch length, which is also applicable to this shorter length. Same screws, same quality, huge time savings over standard Phillips head screws!

"I was building a 3-car, raised, gravel, wood-framed parking area. Needed to frame it up with pressure treated lumber and secure the frame to posts placed in the ground. Similar concept to framing an exterior deck.

After looking at Amazon's selection, I decided to try these self-tapping "star" head screws instead of my normal Phillips head.

Wow was it worth a few more dollars!!!

I used 240 screws and never stripped a screw head ONCE. Also, never had a head bust off (which then forces me to back a screw out with pliers. The self tapping eliminated the need to pre-drill (I may have had one split, but other than that the self-tapping without pre-drilling worked great).

The product came with 5 T25 "star" bits, but I was able to use the same bit for 240 screws with no problem, no stripping.

I'm done with my project, but I'm ordering these screws in several additional lengths, just to have them around when I need them."

I bought these to remove some screws on cabinet hardware. If you look closely there will be what looks like a Phillips head screw with 4 dash marks alongside the four slots.

I learned something new and found out these are Pozidriv (or PZ) screws. I think a Phillips would work but these have a more positive engagement due to some indentations in the screw head. Apparently Phillips screwdrivers are meant to pull out of the head of the screw if a lot of torque is applied so damage can occur to these special screws in some circumstances.

Anyway, these are a nice, inexpensive addition to my tool box when working on these fasteners.

the philips head is not as well made and is not really usable the rest of it is good to go, but hope and pray that you have only flathead screws

Worked fine after I discarded the screws provided & used some of my own that don't fall through. (The heads of those provided were smaller than the holes through which they were to fit).

These are a good solution to hard mount led light strips flush on a wall or onto any flat surface. The screws are a little small so make sure you use the correct sized Phillips head or they will strip out. With the proper sized screw driver/ drill head they work very well.

So much better than regular phillips for anything shimano related. This will not strip out your derailleur limit screws.

Stop stripping screw heads in your RC cars, people!  I know these ain't cheap but they are worth every penny. Stock RC car screws are pretty soft and the ill-fitting tools that are included with most RC cars are terrible. These have saved me so much time, money and frustration. Even one stripped pinion gear screw can ruin your fun for days and even weeks if you don't have a spare. Don't let crappy tools ruin your fun.

Better than my stock screws, the big screw head helps not breaking the screw a lot.

Deserves a five star rating for they installed and fit better than the originals. They looked great on my vehicle and had no issues other than the pain in the but it was to remove the screws and putting them back. I ended up purchasing a specialty tool for 7 dollars that had both phillips and flat head ends at a 90 degree turn. Some youtube videos I found show the tailgate had to come off for installation but I only had to remove the hydraulic shafts that help it come down slowly and lift. I removed the nuts that held them in place going to the tailgate. Hope this helps

I am so glad they sell these things. I somehow managed to turn too hard with my original one that the phillips head bit actually bent the casing sides and allowed the bit to fall out. Luckily I checked amazon to see if replacements were available and seeing a two pack at this price worked great for me (just in case I go Hulk on the new one). The new ones fit perfectly and I would highly recommend them, even as a backup because I can tell you first hand that if yours breaks on you while working it will be a pain in your butt until you order a new one. I'm an electrician so I use my 11-1 all day, my suggestion, get it now!

These worked perfectly, although it took some thought to determine the best orientation for mounting in the chassis I had.  Overall, the only nit pick I have is like most computer equipment/accessories, the screws are not hardened, therefore if you use an orientation that's difficult to get the screws in straight you can easily strip the threads or "over torque" the philips slots...neither of which was an issue for me as I caught the first scenario and have spares for the second...

I was glad, I had ordered these. When my Oben ballhead showed up with nothing in the box to adapt the ball head to a 1/4 thread. So these saved a lot of time from not having to wait and I was shooting instead of waiting for a order to arrive or taking the time trying to find them at a hardware store. Very useful to have on hand, because you never know when you might need to convert a mount. Good thing the package come with several, because these are very easy to lose or miss place. No issues with the vendor.
