Screw selection for locker hinges?

[ash2020]

Csk machine screws they will be called.

But rather than self tappers screwed into the grp I was wondering if machine screws into tapped holes would be better.
I'd screw them in with a dab of epoxy on the threads. If the screws are not cleaned the epoxy won't adhere to them and it will always be possible to unscrew them if necessary. (I use Rapid Araldite if I screw self tappers into the grp. It's the only time I ever use the rapid stuff)

Good idea. Thanks

I Googled set screws as it's a term I rarely hear used. I found 12 different types of set screws, the most common appeared to be what I would call a grub screw.
A screw cuts it's thread when inserted, a machine screw needs a thread to screw in to.

I have always known a grub screw as being a small threaded bolt without a head that disappears into it's threaded hole.

In the US grub screw is on of those weird Britshisms, like spanner for wrench, or Mole wrench for Vice Grip (both of these latter are trademarks, Vice Grip by the Irwin Tool Company being the ealier of the two by a few years). But I understand what you mean.

I think you mean wrench for spanner, not spanner for wrench. I'm sure we were using spanners long before the U.S. was in nappies! (not diapers, note!)

O wouldn't count on that.......my understanding is that current American English is more true to that spoken ( and spelt) in the past than current UK English. Don't know if we're lazy, streamlined or evolving faster....the latter I think...?

I have a bit of a conundrum here. Replacing the cockpit locker lids, I'm using the old solid brass piano hinges which are in very nice condition. I have solid brass screws to go into the wood of the lids but the other side is going straight into the GRP lip of the locker and ideally I need self-tappers as the brass screws are wood screws with a shank and I think would shear going into GRP.
I wouldn't normally like to use stainless up against brass but it looks like I have no option here. Would BZP screws be better? Zinc is nearer to brass on the nobility thingy. Any ideas please?

You might find some ideas here....
Threaded insert in GRP?

So much for a common language huh...?

Box end wrench. Box or Tube spanner (as in a length of pipe formed into an hexagon at either end) (no, totally different in the US. That would be like a socket wrench, used for spark plugs etc. )
Open end wrench. Crows foot is a bent version. Close (but both still spanners!)
Allen wrench (AKA hex key). Allen key (never a wrench) (Allen key is not uncommon)
Socket wrench. Socket spanner, a spanner with a fixed or swiveling socket at either end. Or if interchangeable then just a socket, moved with a bar or a ratchet.
Pipe wrench (also strap wrench, Stilson wrench, and chain wrench). Generally the same for pipe and strap except....Stilsons or a pair of Stilsons, but never a wrench!
And sometimes spanner. But this means a wrench that has to "span" between a pair of indentations, such as a pin spanner. AKA pin wrench. As in pin spanner and C spanner, again neither (pronounced nai ther....) ever a wrench! ?

And then there is the matter if local pronunciations and figures of speech. I've never understood regional non-standard pronunciations.
