In the process of restoring my 24" finger brake I decided to make some new hardware to replace some of the older mangled up stuff like the two phillister head adjustment screws pictured. I changed any nut and bolt adjusting screws to thumb screws and thumb wheels to replace the nuts. Now I don't have to reach for wrenches to adjust any of the settings. I didn't want to single point the two 5/16" - 18 adjustment screws so I made the knurled knobs and decided to get a couple long set screws trim them to length and press fit them into the knobs.
No big deal but I couldn't find any hex socket set screws that are 2 plus inches in length, at least not locally. The threaded rod at the hardware store was pretty well dinged up from all the sliding in and out of the rack. On the way out the girl said wait..... I have one more place to look. They had a shelf with some older boxes of hardware, what luck. She found a box of the old style square head set screws in lengths up to 3". I grabbed a half a dozen of them, like .40 ea. Looking at the boxes these were probably early 70's maybe. Real heavy paper boxes with the perforated metal clips on the box corners. The threads looked so nice and clean, no ridges or ragged edges, unlike the newer stuff you get today. So I went to take a hack saw to cut the square head off one of them and it slid right across it, couldn't scratch it with a file either. These are hard. I've turned set screws in the past with carbide with no issues but wouldn't attempt to try turning these. I may try to anneal them by heating them up with the torch until they turn blue. That should do it right ??? They don't need to be hard.
