Yes at least on mine. You can find longer set screws but not in dog point that I could find (well except Fastenal but they wanted over $2 each!)
Another option would be to either turn down the end of some standard set screws or drill out the end and insert some brass pins.

Fastenal around here doesn't sell individual screws they make you buy the bag... I don't even know how they stay in business no private citizens have any use for the place.... I might try that 1" screw that u suggested earlier they were like 85 cents I think
and just get some thin lock nuts should work pretty good size wise.. now for those half nuts!!!
