Blind hole or through hole, which is better?

  1. Jun 16, 2011 #1

    I had to build an apparatus where I had to join two plates by bolts. I used through holes. Is there any reason why through holes would be better than blind holes? I have an interview and might be asked such question:/

    thur hole
    cheap to manufacturer
    no tap required, no separate thread cutting operation required
    depending upon the material, clamping force of nut and bolt is USUALLY superior to that of tapped i.d.

    in my opinion only plus side of tapped blind hole is less foot print..no ugly nut and bolt threads sticking out...also if access to back side of plate is issue..only choice is to tap the plate..
