Victoria is a nice town, sure it is, but sometimes…
Was looking for 3/8″ UNF lefthanded thread nuts. Tried major fastener outlets, tool and equipment supply place, and a big hardware store. Nope, might as well be asking for a muffler valve.
Ended up borrowing a tap from secret source.
Tip: if you have to make your own 3/8″ nut, UNC or UNF, left or righthand thread, take a 5/16″ nut and drill the threads out with a 5/16″ drill. This gives a pretty good hole for a 3/8″ tap.
Remember to use cutting oil and back off every part turn to clear the chips.
