Brass Machine Screws with Nuts
When small brass machine screws and threaded nuts to fit them are needed in small devices, or for experimental work, and the necessary taps and dies are not at hand, secure some old brass globe holders and cut out the threaded hole for the nut. The fastening-screw arrangement on these will answer every purpose very well. Enough metal can be left on each one to fasten it on wood, as shown at A, or they can be cut, as shown at B, if they are to be soldered to metal.
