Do you know how many custom screws we crank
out on the old Brown and Sharpe screw machines? Custom screws. There
must be, what, fifty million stock screws in the world? And these guys
sit around drawing the parts without any consideration of the fastener,

and then they invent a custom screw to put the widget together. It
isn't
cleverness, it's ignorance.

Then out in the field the new guy looses the screw in the dirt, and
because:

a bolt from the hardware store won't fit the threads

or we don't have the tamper proof Torx socket - with one tooth milled
off - to fit the special screw head

and the foreman says that widget has to be back in service before we
can get a new screw red labled in.........

We just weld it on and let the next guy worry about it :-)
