Id like to give a good or better review and rating but the screws that came with don't work in any of my dewalt tools. Guess Ill find something that will work but disappointed with that part

Only one of the two screws was in the wood handle, as the spacing is too close and they cant both line up.
I will fix it as I have a broken handle now and need this ASAP

Seemed to work fine but a hole formed the third time I used it.

Out of 3 ordered, one failed and got stuck in the open position.

None of the hubs were tapped for the bolts that came with them, not a huge problem since I have a tap but seems like an oversight.  Other than that they worked great!

Spindle is fine, but it showed up with only the mounting screws.  No locknut, spacer, or blade bolt to be found?!?

I am fairly handy so am pretty sure I followed the directions correctly but I couldn't remove a screw since the first step did not create a divot that could be grabbed onto.

It worked for one screw and didn't work for another.  Really need to have proper equipment to use effectively.  Need to secure object properly, create pilot hole with center tap before you begin drilling.  I had problem that entire head of screw was snapped off so this needed extra attention.

My package only came with 3 screws and they were loose in the box and no instructions on how to apply so kinda lost

The unit works but...the 3 screw holes were not threaded.  This is the part that secures to the windshield wiper assembly.  I had to tap the holes which wasn't a big deal for me because I have plenty of tools and do some light machining.  For others, that might be quite frustrating.

3 stars because I suspect this unit did not pass factory QA standards for OEM and somehow fell into 3rd party market - it happens.

Had a problem with one of the 4 brackets.  One bracket had the screw hole that holds the rod in place drilled and located in the wrong place so when the screw was tightened, it pushed the rod up and out rather than securing the rod in place in the bracket.  It didn't matter because I only planned on using 3 brackets for the window I used the curtains on so I didn't need the missed drilled bracket.

The screws were very solid. I used them when I had tricky studs or braces to put in. The square hole size is one larger than the common "red handle" Robertson size.

The size and thread depth was inconsistent, one of them would not thread properly, it kept slipping and one would ride ride up until the knob fell off, it never got tight.  The next one worked fine.  Who knows about the third one.  I looked for the one with the best cut thread after the first failed.  So feel like the third one looked like it would have the same problem.
