    Default Are these dowel pins?

    Hi, got a dozen of these at a shop in Morpeth.

    Not sure what they are but the voices in my head said "BUY THEM", so I did.

    What are they? What are they used for?

    The fine pitch thread is 38mm long as is the coarse thread, with a 20mm blank between, 8mm diameter.

    cheers, billy

    Thumbs up

    I'd say you are right. Funny thing is, I have one just like those. Not as big but in brass. was amongst the FIL's stuphph her in Brasil. Tried to find more to suit a job I was doing but no luck.


    What were you doing in Morpeth? Buying antique Arnott's biscuits?

    to me they look like yhey are for table legs
    you place that through corner brace and screw the course end into leg and then you place nut on fine end
    which pulls your rails and leg together giving you a strong corner
    repeat with all legs
    hope this helps
    cheers macca
    if you google table components or joinery supplies you will find diagram

    Default ta

    Took the MIL to Morpeth for the day, lunch in the pub then while they hit the shops I went to the Trading Post.

    Great shop, tons of stuff all over the place. all the antique tool guys would have a field day in there. all manner of old things.

    I see what you mean about the table legs, thats where Ive seen them. Im not making any tables so dont know what I'll do with them.

    cheers, billy

    Default Hanger screws or bolts

    No, they're not dowel pins. Metal dowel pins are smooth, with a slight chamfer at each end.

    These are usually called "hanger screws" or "hanger bolts." Lag screw threads at one end, and machine threads at the other.

    One function as already described, others as you see fit.

    Cheers,
    Joe

    Lock two nuts together on the fine thread and you have a lag bolt. Drive it into the wood with a spanner/socket then remove the two nuts. Now you have a fixture that you can bolt whatever you desire onto.

    Very handy when you can't drill all the way through a timber to fit a nut'n'bolt... I've used them to mount air-con hangers from timber window frames. (Much easier to install these first than to try doing four hands work with a mere two hands, while balancing precariously on top of a ladder. )
    I may be weird, but I'm saving up to become eccentric.
