Why is one screw on the hinges to my door a Torx?

Heavy exterior door. All the rest are Phillips screws as I expected. The Torx is on the jamb side of a hinge, not into the door itself.

It’s not a security hinge.

I did not install this one. Perhaps the contractor lost a screw and replaced it with a Torx screw? I sort of doubt that though.

It would be easier to drive a Torx deeper/longer screw into the king stud jack stud. But one on all the 3 hinges? One per hinge would kinda make sense.

Why do you doubt it? It seems the most logical explanation to me.

Not that I’ve ever done anything like that. Of course not.

Yes, easier for a longer screw, or perhaps the only long screws available to whoever did it. Is each one in the top hole on the hinge?

If hinge screws get even a little loose and the hinge wiggles, the wiggles will eventually expand the screw hole and the screw can’t really be tightened. To tighten the hinge, it will be necessary to either put something in the hole for the screw to grab on (like a wooden matchstick) or use longer screws to reach the stud. Long decking screws sometimes have Torx heads. I’m guessing the installation was done with a deck screw to make sure the hinge would stay tight. This could have been something proactively done by the installer to avoid problems at a later time.

There is only one Torx, it’s in one hinge and it’s second from the top. Only one Torx. Just kinda weird.

The door weighs about 75 lbs. I I had to pull the hinge pins the other day to remove it. I had to get a neighbor to come help lift it and get the hinges lined up to put it back on.

We still had to use flat bars to lift maneuver it. Both of us big guys.

Maybe that was done. It would be a good solution to drive a deeper screw.

And only on that one hinge? Yeah, sounds like someone ran out of screws.

I’m sorry, I’m wrong. There is one Torx in each hinge on the jamb side. I’m sure for strength. Or he lost three screws. Two other doors also just as heavy (double pane stained glass in it) same manufacturer, new lumber for jambs, don’t have any Torx in those.

Or the manufacturer changed the design. These doors where made ~ within a year of each other.

Or the guy who installed that door has a slightly different way of doing things, and it’s his habit to install a long torx screw on each hinge.

A door that heavy is going to tend to sag over time, causing latching/locking issues. I had one on my last house that was a total PITA. I couldn’t tell if you were saying that the Torx were much longer and reached a stud or not, but it would make sense to me.

Yeah, one on each hinge is intentional.

Yeah, but the same guy installed them all, which is what is confusing to me. I’m thinking design change. Screws are shipped with the door. And it’s a heavy door. Probably got one without the new design and another where someone decided that each hinge needs an extra long screw. Hence the Torx in three hinges.

Odd if they shipped a mix of Torx and non-Torx screws. Maybe they did, sounds intentional but more like an on-site fix or enhancement. Either way, nothing to be concerned about.

Yeah, I’m not concerned. I think I have a Torx for my drill. It just complicates things a bit. I might be pulling those hinges.

Torx is the new standard for screws, so might as well swing with the times. The 2nd hole is usually further towards the framing, too. The first hole it’s easy to slip between the drywall and the stud.

Why? If new hinges have a matching hole pattern you could just use longer screws in the frame and the door. If not both the frame and door are weakened by the old screw holes. The old holes need to be drilled out and dowels glued in. That’s a heavy door so simple tricks to fill screw holes aren’t advised.

Standard practice for hanging a door is to begin with one screw per hinge and check the door for fitting and closing. In this state, the weight is borne on just one screw per hinge, so it makes sense to use a longer, possibly tougher screw for these. Once the fit is tested, the rest of the screws are driven, which can be standard screws as the duty on the screws will be shared by a full set.

Edit: why not just use longer screws for all of them? Cost perhaps. If you’re hanging one door, it’s negligible. If you are a carpenter hanging a couple of dozen doors a day, it makes a difference.

The reason I might remove the hinges is that when I took the door off I forgot a spacer/bushing that the pin goes through. I can just remove the pin and slide the spacer in because of the way it’s designed.

I could pull the door again but it is an absolute bitch to get back on due to how heavy it is. I would have to get my neighbor over here again.

I have a couple of doors like that in my house. My contractor friend noticed the doors were binding in some certain way and grabbed a long deck screw to use to pull the doorframe a little tighter against the rough frame.

The long screw goes through the door frame and into the 2x4 of the rough frame.

As others have said, this is also done as a quick fix when everything starts getting loose (i.e. the small screw holes are getting wallowed out).

Why a Torx? Because the guy reached in his toolbox and found a standard deck screw–these usually are Torx and come with a fancy colored bit tossed in the lot of screws.
