A recently acquired 250-4 is missing the fasteners (screws/bolts) which secure the internals of the amp to the enclosure. Can someone let me know the length, size, thread pitch, bit type and quantity of those screws so I can run to the hardware store and get them?

There are 4 machine screws that hold the chassis into the cabinet.
These are 10/32 type screws and a length of 1.5” to 1 3/4” will work fine.

If it’s hard to get the new ones in any of the 4 holes then you may need a 10/32 tap to get the threads in the nut clips good again.

Also pick up 4 washers and place a small dab of oil on the start of the new screws do they don’t rust to the nut clip.
Another option to the oil and to start off with is some well stocked hardware stores will also carry stainless steel machine screws.
