Default Hurricane Shutter Fastener Hardware Question

I don't know where else to ask because nobody at a hardware store seems to even understand what I'm talking about...

I have direct mount galvanized hurricane shutters. They attach with 1/4"-20 "sidewalk" combo screws that have both a flathead and Phillips slot. Every damn one of them is chewed up and needs to be replaced. I'm not fighting with stripped heads again next hurricane!

The bolt heads must remain round so they fit in the stucco holes properly. But instead of crappy Phillips heads, I want a hex head. So I need a panhead machine screw with a hex protruding from it. This way I can just use a nut driver drill attachment and never strip them.

Complicating further, the house needs painting and I don't want them painting over the new Phillips head screws because then I'll have to pick the paint out of them next storm. If I had a hex head it won't be an issue.

I can't find something like this ANYWHERE yet it's SO obviously the right solution for this application. Has anyone seen anything like this??? Many thanks!

A pic would help. I am not sure I get exactly what you are looking for

Those bolts are made that way specifically so they don't protrude out and a track can be mounted below a door opening. They are made for use with specific lead anchors that are code approved. AFAIK, there is no such thing as what you are looking for.

My suggestion is to buy a bunch more and throw away the ones that get chewed up. Also you can use a large flat head screwdriver to either loosen them first or to remove the chewed up ones.

You can buy 1/4 x20 stainless bolts and use either large washers or the type of rubber faced washers that are made for hurricane shutters as a substitute.

This is what I've got now. Instead of a Phillips head cut into the screw head, I want a 1/4" or 5/16" hex head sticking out.

But what I'm suggesting wouldn't protrude much further than the texture of the stucco anyways. It might add an extra 3/16" or something to the screw height but I can't imagine it making much difference.

The washers won't work though because the shutters are made to barely slip over the pan head screw. This way you don't have to take the screws out to install the shutters - which is a real PITA as I found out the first time I ever tried to put them on!

I think the best you will do is a socket head cap screw.

What you want is not unreasonable. Do you have any contractor supply places that drive around dropping nails to job sites? That would be my first stop.

Matching the threads is going to be key. Once you know the thread size nd count you can head to the inter web where they sell everything. Or take a screw with you to Lowes or a quality hardware store and go hunting for matching threads,

I agree with you hex nut or torx is the way to go with screws.

does that look like a torx slot to any of you?
torx will hold up better than Philips.
but will fill up with piant also unless you put a dab of silicone in each hole before painting.
easier to dig out

I bet you could find someone to weld something to the top of those screws if you cannot find what you want

Kinda looks like you've got steel shutters, aluminum track, stainless bolts, lead lags, and a concrete floor. Sounds like a recipe for a dozen types of batteries and electrolytic reactions.

I don't know why people continue to use phillips screws at at all.
Get some Robertson screws and you'll never have an issue with stripped screw heads again.

Where are you located. Call Action Bolt in Riviera Beach, Florida (561) 845-8800. If they can't find what you are looking for I doubt anyone can.

There is no track and no floor. Just stainless screws into lead lags in my walls.

Too bad they don't seem to make the tapcon style in 1/4 x 20. The Phillips head actually work pretty well but you definitely have to use the right size driver or you'll just tear them up.

If you live in WPB, I'll give you a bunch. I've got plenty.

Apparently I'm not crazy. The type of bolt I am looking for is called a "flange bolt". I found some but the flange is a little too small. They're 0.430" and I need around 0.550".

OK..but if the walls are masonry, you've still got an issue.

Thanks for the offer. I'm in PSL but I need 200 of them, which is more than I would be willing to ask from someone! Easier to just buy two boxes. Thanks though!

You are getting your fasteners confused. If you are saying there is an insert in the stucco then you need to match the thread. You can get 100 different types of screws once you know the thread. If there is no insert, you can use whatever you want that will work on the pre-drilled hole. Suggest going to local fastener store, they'll fix you right up.
