Flanges for Precision Acme Nuts
Thread onto an externally threaded acme nut to create a custom flange nut.
Carbon steel flanges have good machinability. However, they will rust when exposed to moisture. Black-oxide carbon steel flanges have mild corrosion resistance in dry environments and a dark surface color. 303 stainless steel flanges have good corrosion resistance.
