Hello,
I have a legacy drawing that calls out a [B]2X [/B][B].250-20 SL[/B], at two holes from a symmetrical centerline.
Does anyone know what "SL" means, or if this is a standard abbreviation?

Welcome to EE!
I'm not sure about the thread specification - as "SL" normally refers to the screw itself as being "Slotted" Straight.
