Fractional 18-8 Stainless Steel Serrated Flange Hex Locknut

Fractional 18-8 Stainless Steel Serrated Flange Hex Locknuts

Integrated Locking Strength with Corrosion Resistance

Fractional 18-8 stainless steel serrated flange hex locknuts are engineered to provide secure, vibration-resistant fastening without the need for separate washers. Combining a built-in flange with serrated teeth, these locknuts deliver superior holding power while protecting against loosening in dynamic or high-vibration environments.

18-8 Stainless Steel Construction

Reliable Corrosion Resistance for Versatile Applications

Manufactured from 18-8 stainless steel (Type 304), these serrated flange locknuts offer excellent resistance to rust, oxidation, and mild chemical exposure. This makes them well suited for indoor and outdoor use, including humid environments, light washdown areas, and general industrial settings where corrosion resistance is essential.

Serrated Flange Locking Design

One-Piece Fastening with Superior Grip

The integrated flange distributes clamping force evenly across the bearing surface, eliminating the need for a separate washer. Serrations on the underside of the flange bite into the mating surface, creating strong resistance to vibration and rotational loosening. This design improves joint integrity while simplifying installation and reducing component count.

Hex Configuration for Easy Installation

Standard Tool Compatibility

The hex shape allows for quick installation using standard wrenches or sockets, making these locknuts ideal for assembly lines, maintenance operations, and field repairs. The flange also helps prevent damage to softer materials by spreading the load over a larger surface area.

Fractional Thread Sizes

Designed for Standard Inch Hardware

Available in a wide range of fractional thread sizes, 18-8 stainless steel serrated flange hex locknuts are compatible with standard inch-series bolts and threaded rods. This ensures easy integration into existing assemblies without the need for specialty fasteners.

Common Applications

• Industrial machinery and equipment

• Structural and sheet metal assemblies

• Automotive and transportation components

• Electrical enclosures and panels

• HVAC and mechanical systems

Dependable Locking Performance

Reduced Hardware, Increased Efficiency

By combining washer and locknut functionality into one component, fractional 18-8 stainless steel serrated flange hex locknuts improve assembly efficiency while delivering consistent, long-lasting fastening performance.

For corrosion-resistant, vibration-resistant fastening that saves time and reduces parts, these serrated flange locknuts are a dependable solution across a wide range of industrial and commercial applications.
