    I need some help with the name of a particular type of washer.

    Imagine a piece of metal (say the front flap of a wall-mounted
    floodlight) where two bolts are used to retain the flap. Each bolt
    might fall but there is a washer (rubber in this case) which holds it in
    place.

    What is the term used to described that washer?

    I thought it might be called a "retaining washer" but it seems from web
    illustrations that retaining washers are something else.
     
  2. Grommets?
     
  3. If it's made of rubber you may be looking at a grommet.

    Are you describing a narrow shanked bolt, that remains captive but
    slide-abouty after threaded through the "washer"?

    Sounds like small 0-rings to me.

    The message <[email protected]>
    It's just an O-ring usually, turns a screw into a captive screw.

    I'd call it a captive washer. But there's probably nothing special
    about the washer except that it has to have the right internal diameter:
    it's the bolt that's special, in that it has a narrow section without
    thread.

    Or a circlip, in some cases.

    We used fibre washers with hole size that would lock onto the screw.
    Just used ordinary full screws.

    paper washers?, normally paper washers with a small
    hole where the screw and be set into it to prevent the
    screw from falling out is used.

    Essentially, yes.

    Does that help?
     
  12. I propose we call it Wally, wally the washer, sounds cute.
