Joist hanger query
 

I bought some this morning from Travis Perkins, allegedly for 2" wide
joists, which is what I asked for (the receipt says they are 50mm).
However the actual gap into which the joist fits is only 42mm, which
means I'd have to trim 8mm off the joist width for them to fit.

This is my first time using joist hangers (these are timber- masonry)
so forgive the ignorance; but have I been given the wrong size (which I
suspect) or am I supposed to reduce the joists to fit (which sounds
bizarre)?

I'd rather make a fool of myself asking the question here (where the
regulars are rather more forgiving of muppets) than back in TP...

Thanks
David

My joists are a genuine 2" wide, and the hangers I got from Wickes
were also 2". The ones you have are for nominal 2" planed timber,
which is of course smaller.

They're the wrong size - you shouldn't have to trim the joists at all. I've
used these ones in the past:
http://www.screwfix.com/app/sfd/cat/...95710&ts=80393 and 2" fits
fine with 1 or 2 mm to spare.

Genuine question - why would you use planed timber for joists??

If the joists are exposed in the room below?

If they were, that implies the grotty galvanised joist hanger would be
exposed too!

But similarly, when would you ever want joists thinner than 2" anyway?

Anyway - thanks for all the replies: I'm now convinced enough that they
are wrongly sized for me to march back into Travis Perkins tomorrow with
head held high!

They could be designed for the S4S stuff as sold in Wickes.

Beware there are 2 types of joist hanger, one is made from quite
flimsy galv strip steel, the other from welded plate.

You want the last for *real* joist hanging ie to butt a joist against
a wall instead of inserting it into the wall.

I've never been completely clear as to what the flimsy ones are for -
maybe steadying butt joints between timber perhaps? Anyone any ideas?

Also most nominal 2in rough cut joists are not 50mm as you might
expect, but 47mm.

Timber to timber joints.

Its not a question of there being two types, there are different types
of hangar to suit different applications, if you look at the strongtie
site you will see many different types to suit different applications,
generally the heavier duty ones are for masonry fixing, the lighter duty
for timber fixing and don't forget to notch the end of the joist if you
are fixing plasterboard so that it fits flush.

HaHa you didn't see diy sos tonight, their solution was to knock F**K out of
the bottom lip of the hanger

Thanks for all the replies - duly went back to TP today with the
offending items "Oh, sorry mate, must have been in the wrong box" and
now have a set of hangers which fit perfectly .

I did see it, made me grin, room looked all right afterwards, I have
doubts about the timing of these programs as a lot of what they do needs
to dry before they can do much else
