Greetings...



I remember seeing an article on how to fabricate hold-down screws for db connectors

installed with no shells, but now can't locate it. I know it's not exactly rocket science, 

but would like to re-read the article. I'm pretty sure it was aeroelectric list related...

Thanks!

I went to a general store, but they wouldn't let me buy

anything specific.

PS: Phillips drive machine screws are an abomination. Every builder who has 

converted to the Torx (6 lobe) drive screws has been delighted with the 

results.

Hello Fellow Builders, Here is what we are writing about:



http://en.wikipedia.org/wiki/D-subminiature



Bob Nuckolls writes: "It's a fact that the majority of d-sub connectors come

with short, slotted-head 4-40 jack screws that are EXCEEDINGLY

    difficult to work with in confined spaces traversed by wire

    bundles." ..and ... "the inconvenience of stock, slot-head jack-screws."



{RESPONSE}  He offers a screw handling solution here:

I'd like to offer another solution -- use #4-40 machine screws with hex

socket (Allen wrench) drive heads. The hex socket drive head allows one to

manuever the small screws in a manner vastly superior to a straight slot or

phillips drive head screw.



See here for a source of such screws:



http://www.microfasteners.com/catalog/products/SSC.cfm



Here is just one source of tools for handling these screws:



http://www.bondhus.com/



Conventional Allen wrenches work fine for most handling of these screws, but

these Prohold tools will give even more control if needed:

understand knowledge."



PS: An aerospace vehicle with hex socket or Torx / six lobe / star drive

fasteners is much easier to work on than a vehicle with straight slot or

Phillips drive fasteners. See here for some handy tool kits to work with the

hex socket or Torx / six lobe / star drive fasteners:
