Steel Flange Nuts

Steel flange nuts are zinc-plated hex nuts with an integrated, wider flange that acts as a built-in washer — spreading clamp load and eliminating a separate washer. The general-purpose flange nut for everyday assembly.

For vibration resistance choose serrated (Gibraltar) flange nuts; for corrosion resistance, stainless.
