M3.5 Stainless Screws, Phillips Head, 120 degree countersink, Bag of 25
Doing a new panel for your Yak? How about replacing those funky Russian instrument screws with Phillips heads?
An idea whose time has come !
These Russian panel screws have a 120 degree, (rather than the more familiar 100, 90 or 82) countersink, presumably to contact a greater area on the panel and resist backing out under vibration.
Most Flight instruments in the Yak’s panel take M3.5 size (while the Russian Tach takes an M4), but both sizes, with these shallow cross-slotted heads, are to be found throughout the cockpit area.
In a lot of cases you'll see the slot simply got smeared by the torquing tool, making them almost impossible to remove.
(Decoded: a Philips screwdriver is not the right tool for these particular Russian screws.)
Wherever you see a gauge surrounded by one slotted head screw and three crossheads, leave the slotted one in place.
The Carb Inlet temp, Tri Gauge and the dual air pressure gauge are like this - they are packaged as cylindrical cans without a front mounting flange. Undo the slotted screw a few turns and, behind the panel, a wedge moving on that thread is releasing a cylindrical clamp ring, held in the panel by the other three screws.
Instruments like this slide out forward.
