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

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.

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.

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 Phosphate-Coated Steel—The dark coating creates both a finished appearance and a barrier against rust that withstands occasional exposure to moisture.

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.

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.

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

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.

Self-Aligning Flange Nuts

Clamp workpieces that aren't perfectly parallel to the mounting surface. Also known as spherical collar nuts, these have a curved base and washer that fit snugly together and swivel to compensate for slight misalignment. Nuts distribute pressure evenly as they tighten to prevent damage to the part.

Height includes the nut and the washer.

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.

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.

High-Strength Steel

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.
