Medium-Strength Steel Serrated Flange Locknuts—Grade 5
These flange locknuts have serrations that grip the material surface instead of the threads for easy installation and mild vibration resistance. The flange distributes pressure where the nut meets the material surface, eliminating the need for a separate washer. Made from Grade 5 steel, they're suitable for fastening most machinery and equipment. A zinc plating provides corrosion resistance in wet environments. Height includes the flange.

Metric Medium-Strength Steel Serrated Flange Locknuts—Class 8
Strong enough for use in most machinery and equipment, these medium-strength metric nuts have serrations on the underside of the flange. The serrations prevent the nuts from loosening in applications with mild vibration.
Also known as collar nuts, they do not require a washer, which saves assembly time. Instead, the flange spreads the holding force across a wide area. Because the flange makes them wider than standard nuts, they may not fit into tight spots.
Zinc-plated steel nuts have a layer of zinc on the outside that prevents the steel from rusting in wet environments, extending the life of the nut.
To ensure compatibility with other parts and tools, some nuts meet ISO 4161 (formerly DIN 6923).

Low-Strength Steel Serrated Flange Locknuts
Serrations grip the material surface instead of the threads for easy installation and mild vibration resistance. The flange distributes pressure where the nut meets the material surface, eliminating the need for a separate washer. About half the strength of medium-strength steel flange locknuts, use them in light duty fastening applications, such as securing access panels. Height includes the flange.
Black-oxide steel flange locknuts are mildly corrosion resistant and have a dark surface color.
Zinc-plated steel flange locknuts resist corrosion in wet environments.
Zinc-flake-coated steel flange locknuts are more corrosion resistant than zinc-plated steel flange locknuts. They are comparable to Magni-coated locknuts.

18-8 Stainless Steel Serrated Flange Locknuts
Made from 18-8 stainless steel, these flange locknuts have good chemical resistance and may be mildly magnetic. Serrations grip the material surface instead of the threads for easy installation and mild vibration resistance. The flange distributes pressure where the nut meets the material surface, eliminating the need for a separate washer. Height includes the flange.

Stainless Steel Distorted-Thread Flange Locknuts
These flange locknuts have excellent resistance to chemicals and salt water. They have an irregularly shaped thread that grips the bolt for a stronger hold than nylon-insert flange locknuts. A flange distributes pressure where the nut meets the material surface, eliminating the need for a separate washer. These nuts may be mildly magnetic. Height includes the flange.
18-8 stainless steel nuts have a serrated flange—the serrations grip the material surface for mild vibration resistance. These nuts can be used multiple times.
