Screwing into a patio door what type of screw needed?

[kubera]

Hi

I am trying to install a patio door push lock into my double glazing door frame, i have drilled 2mm holes into the frame, but im finding the screws that came with the push lock wont screw into the frame, tried several different phillips screw drivers so its not that.

I dont know what material the frame is made out of aluminium or steel, is there some sort of special screw that will easily go into this?

Is the pilot hole too small ?

Find a similar bit of material and practice.

Don't just step up a drill size, try running the drill through the hole a few times to open it up a bit (on your practice bit of material)

The screws should be self tappers.

Its a standard push lock from screw fix, seems like the right type of screws but just wont go in after a couple of mm, no point in forcing it and damaging the screw head..

Often the screws that are supplied with locks etc are really pants. Go buy some decent screws from your local hardware store.

You think the head of the supplied screws are just not upto standard and thats why it wont grip the screw driver?

 

[Bilioustrumpstaine]

Quite possible.

I am going to ask a question here and if it appears very basic I apologise.

Are you using the correct screwdriver bit, by that I mean have you perhaps got a phillips screw and are using a pozi bit. This would cause the head of the driver to fall out of the screw.

I was replacing some under pelmet lights the other day and tried to use the screws provided and even going into wood with a pilot hole I couldn't get them started so I chucked them and used some decent Spax screws the same size, straight in, no probs.

Retested with another screwdriver which is gripped the head of the screw pretty hard, but still not going into the pilot hole.

Is there specific scews available that will go into the material of my patio door frame?

 

[Bilioustrumpstaine]

Self tapping screws are what you need, preferably from a good manufacturer such as Spax.

You have drilled a 2.0 mm hole, is this the size specified in the fitting instructions ?

 

[kubera]

Insructions are bogus, just says drill the hole doesnt give a size, cant find span self tapping screws.

What about these?

How about some TEK Screws?

 

[kubera]

These are the all the self tapping ones screw fix sell.

Where can I purchase the Tek ones?

 

[Bilioustrumpstaine]

Make the pilot hole a tad bigger by running the drill through it a couple of times.

Go to your local hardware store where you will be able to buy screws singly.
