"Budget" and "USA-made" are not generally in the same Venn circles these days. But you generally do get what you pay for.
Pliers, Screwdrivers, and electrical-related tools: Klein. Their Taiwan-sourced stuff is quite good, though.
Ideal still has some USA-made screwdrivers and pliers, but I've noticed most of their pliers are now China-sourced since Ideal sold off SK (and the tooling).
Some Southwire pliers and screwdrivers are made in USA. The former are made by Pro-America, but they are not as nice as Klein.
Milwaukee will have a range of pliers and other hand tools that will be made in USA very soon.
Williams and Tekton make good screwdrivers in the USA. Proto used to be all USA, but now the shanks are imported. Channellock acetate-handle drivers are also good, but they probably won't be around much longer since they are sourced from Ideal.
Channellock and Wilde both make great pliers for the money.
Malco makes high quality tools for HVAC and sheetmetal work.
Hammers: Vaughan and Estwing.
Wrenches: Proto, Williams, and Tekton (angle-head wrenches only). Craftsman will be an option again soon.
Sockets and Ratchets: Williams, Proto, and SK (if you can find them). Again, Craftsman will soon be an option again.
Pry Bars, Chisels, Punches: Mayhew and Wilde.
Power Tools: Most are made in China, but DeWalt has some that are mostly made in USA.
Some Lenox saw blades are USA-made. Milaukee has some as well.
Zephyr makes insert bits and power bits in the USA. Apex did, but they seems to have moved to China-sourced bits.
Norsman makes drill bits here.
Adjustable Wrenches: You are out of luck, since Wester Forge was the last US manufacturer of those, and they made them for pretty much every other brand. Either go used, or go Channellock, which are made in Spain, and are quite good.
Check out the Truck Tool thread that's sticky. A lot of Snap-On/Mac and all Matco tools are made by other companies, including some in America.
