Did my roof with the torque set on my drill. You still have to be attentive because the density of the wood changes and screws can be left proud or washers mashed down.
I see these have a grove on the tip of the screw, are they also self tapping screws? (FIY, It would have been a nice touch to have shown that they also self drill through metal, if they do that, that is)
Yes, they are designed to self-drill through metal into wood. A different type is available for metal-to-metal which have a drill point on the end instead of a sharp point.
if you can see the rubber after its screwed down it will deteriorate, use a screw that completely covers the screw, thry cost more but last forever not a couple years, your type screw could be used on siding but not roof
If you don't mind the extra hassle, is there any reason not to put a dab of silicone or some other caulk on each screw before you install it? It seems like this could greatly extend the life of the screws.
The EPDM gaskets used are a long lasting quality - also 90-95% of the gasket is covered by the metal washer. Properly installed there should be no need for an additional sealant. It wouldn't hurt anything, but it would be quite tedious.
Properly installed, they generally last the 40 years of the roof and up. I still recommend they be inspected at about 20-25 years. The metal umbrella washers on modern metal roof fasteners cap about 95% of the EPDM seal - protecting it from UV rays and allowing them to last much longer vs the old roofing nails where the rubber (usually a lower grade than EPDM) was 90% exposed to the sun. The metal cap is galvanized and painted to match.
A recommendation would be to use roofing grade sealant in the hole first if going back in with the same size screw. Otherwise and in a perfect world, use either an oversized screw in the same hole or a stitch screw (a short oversized screw that would basically just seal the hole, not add holding power).
Thanks for the tip...

Great point!
Very true
CEO of proper torque

That's right! Exposed gaskets will eventually breakdown from UV exposure. We recommend a fully encapsulated multi-seal washer just like you suggested.
Can you please tell what screw is best

I’ve thought about this too
Soo....A..TORQUE SPEC ....THAT'S ALL👍🇲🇽💯
That's definitely important!
How long you think that rubber grommet will last?

Why show a thumbnail of zxl dome screw...yet give demo with standard type?? I was excited to see a dome head demo.☹️
Say that I over screwed it. Can I really go back, replace the screw with another one, and screw in the same hole with the new screw?

I mean, isn’t the cap that prevent the water , not the screws🤔🤔🤔🤔🤔🤔🤔📶🍧🔥🌳💯💤
The rubber washer under the cap provides the watertight seal.
its a mandatory feature nothing to do with the actual screw ,anyone using this tool and that screw would know that
The firs thing you could do is learn how to hold your camera horizontal it is not that hard.vertical is pathetic.
Thank you Robert - I appreciate the feedback!
