S0-239 Mounting screws and nuts questions

[KU4UV]

Hi gang,

I am in need of some mounting screws like the type used for Amphenol SO-239 coax jacks.  These are the common SO-239 panel-mount jacks that have the 4 holes that are used to mount the jack.  I have ordered some Amphenol jacks from Mouser, but these don't come with the screws and nuts used for mounting.  Short of calling Amphenol or MFJ or another company, can someone point me in the right direction as to where I need to go to find these screws and nuts?  What type of screws and nuts are used?  I might be able to go down to the local hardware store and find them, I just need to know what type to get.  Thanks a bunch for any help you can provide.

I usually use #4-40 hardware, available at your local Radio Shack.

Use whatever size screw will fit through the hole.  The local
hardware store should have them in both SAE and metric
sizes.  I've even used sheet metal screws instead of machine
screws with nuts, or you can tap the hole to a specific thread
(after drilling it out slightly if needed) and eliminate the need
for a nut.  You can even install them with pop rivets - it really
isn't critical.

A real "made-to-print" SO-239 will use a number 4 machine screw. A number 4-40 machine screw and nut would work well. Some foreign SO-239 connectors will accept a number 6 machine screw, which commonly is a national fine thread 6-32 machine screw.

Next time you order something from Mouser, order a quantity of 4-40 screws, lockwashers and nuts.  They're sold separately and are quite a bit cheaper than you'd find in a hardware store or Radio Shack.
