Go find a local hardware store, it will require about 200 yards less walking and they never blink when you say 'can I try this'. I went to sears to get a Torx socket, they wanted me to buy the 3 I wanted to try then return the two I didn't need. Screw that, my times worth more to me, besides I'd rather support the local then the big box stores. LOL, my local hardware store has been stocking and selling nuts and bolts for over a 100 years, I've seen boxes there dated 1908, if you can't find it there they don't make it... they even have original hand cut nails for cristsake. It was a sad day when they did away with the gun section, it was nice going in for some nuts and bolts then picking up a box .45's.
