Serrated Flange Nuts

Serrations bite into material for mild vibration resistance while the flange eliminates the need for a separate washer. These nuts are ideal for securing screws in oversized or irregularly shaped holes since the flange covers a larger area than standard nuts. You can use them again and again without sacrificing strength. However, the serrations may mar the surface of your material. Also known as collar nuts.

Rated Grade 5, Grade F, or Class 8, these nuts are your go-to for fastening most machinery and equipment. To avoid stripped threads during installation, make sure your screw has a comparable strength rating.

Zinc-Plated Steel—A step up from plain steel, the zinc plating withstands occasional exposure to moisture.

Zinc-Yellow-Chromate-Plated Steel—With a more durable finish than clear zinc plating, these nuts are suitable for most wet and outdoor environments. However, they won't hold up to the harsh chemicals that stainless steel can.

Black-Oxide Steel—Typically chosen for their appearance, these nuts have a dark, matte coating that creates a finished look. They offer minimal corrosion resistance, so they're best for dry environments.

Steel—Best for dry environments since moisture will cause these nuts to rust.

High-Strength Steel

Rated Grade 8, Grade G, or Class 10, these are about 25% stronger than medium-strength steel nuts. They are commonly used to fasten components in valves, pumps, and motors. To avoid stripped threads during installation, make sure your screw has a comparable strength rating.

Zinc-Plated Steel—A step up from plain steel, the zinc plating withstands occasional exposure to moisture.

Phosphate-Coated Steel—Paint adheres evenly to the surface of these nuts, so you can add your own decorative finish. They are more durable than zinc-plated steel nuts to withstand wet and outdoor environments. However, they won't hold up to the harsh chemicals that stainless steel can.

Black Phosphate-Coated Steel—The dark coating creates both a finished appearance and a barrier against rust that's more durable than clear zinc plating.

Steel—Best for dry environments since moisture will cause these nuts to rust.

Low-Strength Steel

About half the strength of medium-strength steel nuts, these are suitable for light duty fastening applications, such as securing access panels. Use them with screws that have a similar strength rating to avoid stripping threads during installation.

Zinc-Plated Steel—A step up from plain steel, the zinc plating withstands occasional exposure to moisture.

Zinc-Flake-Coated Steel—The most durable zinc coating, zinc flake is a multilayer finish that resists wear for long-term rust protection. Similar to zinc yellow-chromate, it won't hold up to harsh chemicals like stainless steel can.

Flange Nuts

No need for a separate washer—these nuts have a plain flange that distributes pressure evenly for a wide variety of fastening applications. They are ideal for securing screws in oversized or irregularly shaped holes since the flange covers a larger area than standard nuts. Also known as collar nuts.

Medium-Strength Steel

Nylon-Insert Flange Nuts

A nylon insert grips the screw for a stronger hold than a serrated flange, without damaging threads or marring the surface of your material. However, the insert may become brittle if exposed to high temperatures. These nuts have a flange that distributes pressure evenly across the mounting surface, so you don't need a separate washer. They are ideal for securing screws in oversized or irregularly shaped holes since the flange covers a larger area than standard nuts. You can reuse them a handful of times, but their holding power will decrease with each use. Also known as collar nuts.

Distorted-Thread Flange Nuts

The strongest hold of all the flange nuts we offer, these have irregularly shaped threads that grip the screw to resist loosening. The threads prevent the nut from backing out due to high vibration, but they also increase the effort to install and remove. To get these nuts off, you may need special tools, such as an impact wrench or propane torch, so they are not reusable. Nuts have a flange that distributes pressure evenly across the mounting surface without the need for a separate washer. They are ideal for securing screws in oversized or irregularly shaped holes since the flange covers a larger area than standard nuts. Also known as collar nuts.

High-Profile Flange Nuts

30% taller than standard-profile nuts, these have a large gripping area so your wrench or socket won't slip off as you tighten them. They also engage more threads for extra gripping power. Nuts have a flange that distributes pressure evenly across the mounting surface without the need for a separate washer. They are ideal for securing screws in oversized or irregularly shaped holes since the flange covers a larger area than standard nuts. Also known as collar nuts.

High-Strength Steel

Steel—Best for dry environments since moisture will cause these nuts to rust.

Rotating Flange Nuts

The head of these nuts rotates while the flange remains stationary, so you won't scratch the surface of finished parts as you tighten. They distribute pressure evenly across the mounting surface without the need for a separate washer. Also known as collar nuts.

Thread-Repairing Flange Nuts

Clean and reshape damaged threads while fastening parts together. Similar to a die, these nuts cut through rust, residue, and weld spatter as they screw on and off to ensure strong connections and prevent sticking during assembly. They have a flange that distributes pressure evenly across the mounting surface without the need for a separate washer. Also known as collar nuts.

12-Point-Drive Flange Nuts

The star-shaped head has more points of contact than a hex head nut, so you can achieve a better grip and a tighter fit without flattening the sides of the nut. Great for cramped spaces without a lot of clearance, these nuts twist on from any angle with a standard wrench. They have a flange that distributes pressure evenly across the mounting surface without the need for a separate washer. Also known as collar nuts.

JIS Flange Nuts

Fasten parts and components that are made to Japanese Industrial Standards. These nuts have a flange that distributes pressure evenly across the mounting surface without the need for a separate washer. Since the flange covers a larger area than standard nuts, these are ideal for securing screws in oversized or irregularly shaped holes. Also known as collar nuts.

Medium-Strength Steel

Mil. Spec. Distorted-Thread Flange Nuts

Not only do these have the strongest hold of all the flange nuts we offer, they are also manufactured and tested to strict U.S. military standards for material and construction. They have irregularly shaped threads that grip the screw to resist loosening in high-vibration applications. The threads prevent the nut from backing out, but they also increase the effort to install and remove. To get these nuts off, you may need special tools, such as an impact wrench or propane torch, so they are not reusable. Nuts have a flange that distributes pressure evenly across the mounting surface without the need for a separate washer. They are ideal for securing screws in oversized or irregularly shaped holes since the flange covers a larger area than standard nuts. Also known as collar nuts.

Low-Strength Steel

Image of Product. Front orientation. Flange Nuts. Mil. Spec. Distorted-Thread Flange Nuts.

About half the strength of medium-strength steel nuts. Use them with screws that have a similar strength rating to avoid stripping threads during installation.

Cadmium-Plated Steel—The plating reduces friction during installation, so these nuts thread on smoother than others. It also creates a barrier against rust that's comparable to zinc yellow-chromate plating.

Cadmium Yellow-Chromate-Plated Steel—Better corrosion resistance than plain cadmium. These nuts withstand salt water and are suitable for most wet and outdoor environments.
