Title: Mounting screws
Post by: davidwpack on May 29, 2017, 01:04:58 pm

Hey there. Could someone provide me with the proper mounting screws sizes for an 018343 OT and also screw sizes for mounting tube sockets. I'm getting ready to do an order and not sure what sizes. Thanks.

use #8 pan head machine screws if in the USA, or M4 for the rest of the world. M5 don't fit - the slot opening is .187" or 4.75mm.

I use 4-40 for tube sockets. Usually 8-32 for transformer unless it's a huge transformer.

Thanks. I thought about using rivets for the sockets but thought better of it.
