Non-Serrated Nuts: Non-serrated nuts, also known as plain nuts, are the simplest and most common type of nut. They feature a smooth surface without any serrations or locking features, making them easy to install and remove. Non-serrated nuts are used in a wide range of applications where vibration resistance is not a primary concern.

Finished Hex Nuts: Finished hex nuts, as the name suggests, have a hexagonal shape and a finished appearance. They are often used in applications where aesthetics are important, such as furniture assembly or architectural hardware. Finished hex nuts are available in various materials and finishes to suit different requirements.

Structural and Heavy Hex Nuts: Structural and heavy hex nuts are designed for use in structural applications where high strength and durability are required. They feature a thicker profile than standard hex nuts, providing greater resistance to deformation and shear forces. These nuts are commonly used in construction, bridge building, and infrastructure projects.

Hex Jam Nuts: Hex jam nuts are thinner than standard hex nuts and are used in applications where space is limited. They are often used as a locking nut to secure bolts in place or as a spacer between components. Hex jam nuts are available in various sizes and materials to suit different applications.

Machine Screw Nuts: Machine screw nuts, also known as small pattern nuts, are designed to be used with machine screws. They have a smaller profile than standard hex nuts and are often used in tight spaces or for delicate applications where a larger nut would be impractical.

Nylon Insert Locknuts: Nylon insert locknuts, also known as nyloc nuts, feature a nylon insert that provides resistance to vibration and loosening. When the nut is tightened, the nylon insert creates friction between the threads, preventing the nut from backing off. Nylon insert locknuts are commonly used in automotive, machinery, and aerospace applications.

All Metal Locknuts: All metal locknuts, also known as prevailing torque nuts or stiff nuts, feature a metal locking mechanism that provides resistance to vibration and loosening. Unlike nylon insert locknuts, which rely on friction between materials, all metal locknuts use deformation of the metal threads to create locking action. They are commonly used in high-temperature or high-vibration environments.

Acorn Nuts: Acorn nuts, also known as cap nuts, feature a domed top that provides a finished appearance and prevents snagging on clothing or other objects. They are commonly used in decorative applications, such as lighting fixtures or railing systems, where appearance is important.

Coupling Nuts: Coupling nuts are elongated hex nuts with threads on both ends. They are used to connect two threaded rods or studs together to extend their length. Coupling nuts are commonly used in construction, plumbing, and electrical applications.

Slotted Hex Nuts: Slotted hex nuts feature slots cut into the top of the nut, allowing for easy installation and removal with a screwdriver or wrench. They are commonly used in applications where frequent assembly and disassembly are required, such as machinery or equipment maintenance.

Square Nuts: Square nuts have a square shape instead of a hexagonal shape, preventing them from rotating when tightened. They are commonly used in wood or other soft materials where a standard hex nut might embed itself.

Tee Nuts: Tee nuts, also known as T-nuts or blind nuts, are designed to be embedded into wood or other materials. They feature a threaded barrel that provides a secure anchor point for bolts or screws. Tee nuts are commonly used in furniture assembly, cabinetry, and woodworking projects.

Wing Nuts: Wing nuts feature two large wings that allow for quick and easy hand tightening. They are commonly used in applications where frequent assembly and disassembly are required, such as machinery or equipment maintenance.

Wheel Nuts: Wheel nuts, also known as lug nuts, are used to secure wheels to axles. They are typically made of steel and feature a tapered seat to ensure proper alignment and torque distribution.

Axle Nuts: Axle nuts are used to secure axles to hubs or shafts. They are commonly used in automotive, agricultural, and industrial applications.

Speed Nuts: Speed nuts, also known as self-retaining nuts or spring nuts, feature a pre-installed captive spring that provides quick and easy installation. They are commonly used in assembly line applications where efficiency is key.

Metric Flange Nuts: Metric flange nuts feature a built-in washer-like flange that distributes load forces and prevents over-tightening. They are commonly used in automotive, machinery, and appliance assembly.

Stainless Hex Nuts: Stainless hex nuts are made of stainless steel, providing corrosion resistance and durability in harsh environments. They are commonly used in marine, food processing, and outdoor applications.

Stainless Coupling Nuts: Stainless coupling nuts are elongated hex nuts made of stainless steel. They are used to connect two threaded rods or studs together in corrosive environments.

Stainless Locknuts: Stainless locknuts feature a locking mechanism that provides resistance to vibration and loosening. They are made of stainless steel for corrosion resistance and are commonly used in marine, aerospace, and chemical processing applications.

Stainless Tee Nuts: Stainless tee nuts feature a threaded barrel that provides a secure anchor point for bolts or screws. They are made of stainless steel for corrosion resistance and are commonly used in marine, food processing, and outdoor applications.

Brass Nuts: Brass nuts are made of brass, a copper alloy known for its corrosion resistance and electrical conductivity. They are commonly used in plumbing, electrical, and decorative applications.

Silicon Bronze Nuts: Silicon bronze nuts are made of silicon bronze, a copper alloy with excellent corrosion resistance and strength. They are commonly used in marine, architectural, and artistic applications.

Aluminum Nuts: Aluminum nuts are made of aluminum, a lightweight metal known for its corrosion resistance and low density. They are commonly used in automotive, aerospace, and electronics applications.

Material and Grades

Nuts are available in several different grades, each offering specific properties and characteristics to suit different application requirements. When selecting the appropriate grade of nuts for your application, consider factors such as required strength, corrosion resistance, and environmental conditions. We offer a wide range of nuts in various grades to meet the diverse needs of our customers across different industries. Here are some common grade options for nuts:
 
Grade 2: Grade 2 nuts are the most basic nuts, suitable for general-purpose applications where high strength is not required. They are commonly made of low or medium carbon steel and are not heat-treated.

Grade 5: Grade 5 nuts offer higher strength than Grade 2 nuts and are commonly used in automotive and machinery applications. They are made of medium carbon steel and are quenched and tempered for added strength.

Grade 8: Grade 8 nuts are the highest grade of standard nuts, offering exceptional strength and durability. They are commonly used in heavy machinery, automotive, and structural applications. Grade 8 nuts are made of medium carbon alloy steel and are heat-treated to achieve their high strength.

Stainless Steel: Stainless steel nuts provide corrosion resistance and are suitable for applications where exposure to moisture or chemicals is a concern. Common stainless-steel grades include 18-8 (Type 304) and 316 stainless steel, offering varying levels of corrosion resistance.
