Use these handles for quick assembly and disassembly. Their offset grip provides leverage, making them a good alternative to wing nuts. Long shafts can thread through these handles for mounting versatility.
Iron handle nuts with a zinc-plated finish have corrosion resistance.
Steel handle nuts are stronger than iron.
Stainless steel handle nuts have excellent corrosion resistance, making them the best choice for harsh environments. They also have good chemical resistance.
