I had a problem with the DB9 on my Lightspeed ignition coming loose.Â  A Lancair builder put me on to these screws



AN500-AD4-7

 

which I ordered from aircraft spruce.Â  They are drilled fillister head screws and were perfect for the task.

 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!

Hopefully that's what you were after.

You can purchase ready made connector hold down screws from Stein Air, in Minnesota.  They are about 1.5" long and have a knurled post.  I bought several and will be switching them out every time I undo a connector. 



They may not be in the on-line offering.  Just give them a call, they are very helpful.

 Hello J. Davis, You wrote: ".....how to fabricate hold-down screws for db connectors

 See my posting of 5/29/2010 copied below.

 

 'OC' Baker Says: "The best investment we can make is the time and effort to gather and understand knowledge."

 

 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:

 

 http://tinyurl.com/34nrdd5

 

 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:

 'OC' Says: "The best investment we can make is the effort to gather and

 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:
