Fractional 316 Stainless Steel Serrated Flange Hex Locknut

Fractional 316 Stainless Steel Serrated Flange Hex Locknuts

Maximum Corrosion Resistance with Built-In Locking Power

Fractional 316 stainless steel serrated flange hex locknuts are designed for demanding applications where superior corrosion resistance and vibration-resistant fastening are critical. Featuring an integrated flange with serrated teeth, these locknuts provide strong, washer-free locking performance while standing up to harsh environments that defeat standard fasteners.

316 Stainless Steel Material

Superior Protection in Extreme Environments

Manufactured from Type 316 stainless steel, these locknuts offer enhanced corrosion resistance compared to 18-8 stainless, especially in the presence of chlorides, saltwater, chemicals, and coastal or marine atmospheres. The addition of molybdenum improves resistance to pitting and crevice corrosion, making 316 stainless the preferred choice for severe service conditions.

Serrated Flange Design

Vibration Resistance Without Extra Hardware

The wide, integrated flange distributes clamping force evenly across the mating surface, eliminating the need for a separate washer. Serrations on the underside of the flange bite into the contact surface, creating strong resistance to loosening caused by vibration, movement, or thermal cycling. This one-piece design improves joint reliability while reducing assembly time and component count.

Hex Locknut Configuration

Easy Installation and Secure Fit

The standard hex shape allows for quick installation using common hand tools or power tools. The flange also helps prevent damage to softer materials by spreading load pressure, improving joint integrity in thin or slotted materials.

Fractional Thread Sizes

Compatibility with Standard Inch Hardware

Available in a range of fractional (inch-series) thread sizes, these serrated flange hex locknuts are ideal for use with standard bolts, threaded rod, and studs commonly found in industrial and commercial equipment.

Typical Applications

• Marine and offshore equipment

• Food processing and washdown environments

• Chemical processing facilities

• Outdoor structures and coastal installations

• Industrial machinery exposed to corrosive conditions

Reliable Locking, Long-Term Performance

Designed for Harsh Conditions

Fractional 316 stainless steel serrated flange hex locknuts deliver dependable locking strength, reduced maintenance, and exceptional corrosion resistance—making them a trusted fastening solution for critical applications where failure is not an option.
