These special metric fasteners are special ordered from China, and metric. You might find something close in SAE, but not like the original one. What brand of chair... are they on? Best Wishes In a message dated 3/2/2017 7:12:23 P.M. Central Standard Time, [email protected] writes:

So you can slide brackets on and screw things to it. I think they are called Slot Nuts. I can find T shaped ones, but I need square or rectangled ones. Anyone know where to buy these? I need like a 1/4 inch thread, about 3/4 wide. Thanks much, Greg
