Thread Class	2B
Flange Style	Serrated Flange Nuts

Hex nut with an integral serrated flange. The flange spreads load like a built-in washer and the serrations bite the bearing surface to resist loosening; a washer under a serrated flange defeats them.

Dimensions conform to IFI-100/107 and may vary within specified manufacturing tolerances.
