A barrel nut, also known as a binding nut or barrel screw, is a type of fastener that has a cylindrical shape with internal threads. It is typically used in conjunction with a bolt to create a strong and secure connection.
Our lock nut is crafted from high-quality materials such as stainless steel, carbon steel, copper, alloy steel, and more. This diverse range of materials ensures that our lock nut is suited to your specific requirements. We prioritize customization, allowing you to choose the material that best suits your application.
Nuts and screws are commonly used in our daily lives. There are many types of nuts, and ordinary nuts often come loose or fall off automatically due to external forces during use. In order to prevent this phenomenon from happening, people have invented the self-locking nut we are going to talk about today, relying on their intelligence and intelligence.
Nuts are indispensable partners of bolts: they realize fastening via thread meshing, providing stable clamping force for structures. As core detachable connectors, they are widely used for easy installation, flexible disassembly and strong adaptability.Their materials (usually brass, carbon steel, stainless steel) match bolts, and they are often zinc-plated or nickel-plated to enhance corrosion resistance. Nuts work in various scenarios—from rugged industrial machinery to sensitive electronic instruments—offering essential, reliable fastening to keep structures safe.
Different nut designs are tailored to specific requirements - anti-loosening and shock resistance, space constraints or appearance requirements.The following are several mainstream types:
Hexagonal nut:The most classic type of nut, with a hexagonal appearance that fits standard wrenches or socket tools.A simple structure means an efficient disassembly and assembly experience as well as smooth torque transmission, making it suitable for scenarios that require frequent adjustments.It is commonly used in the bases of heavy machinery, engine brackets of automobiles, power generation equipment, and components of rail transit.
Flange nut:It is equipped with an integrated gasket design.The flange ring extended at the bottom can increase the contact area, prevent the thin plate material from being damaged by pressure, and at the same time provide a certain anti-slip effect.It is commonly used in automotive chassis, fluid pipe connections, and sheet metal casings.
Square nut:The square design provides a larger support surface and is less likely to rotate during installation, making it particularly suitable for load-bearing structures. It is often used for fixing the guide rails of heavy machine tools and connecting the frames of agricultural machinery and industrial conveyors.
sleeve nut:Made of stainless steel and other materials, the hexagon socket structure facilitates tool operation. The pad design increases the contact area and stabilizes the connection. It is widely used in fastening scenarios in mechanical, electronic and other fields.
The selection of nuts directly affects the safety and durability of the overall structure. The main application fields include:
1.Industrial Machinery and Automation
Common types: hexagonal nuts, square nuts
Typical scenarios: Fixing the frame of the conveying equipment (square nuts ensure stable load-bearing), tightening the joints of the mechanical arm (hexagonal nuts facilitate torque adjustment), and locking the motor base (carbon steel hexagonal nuts ensure strength).
2.Automobile traffic
Common types: flange nuts, slotted nuts
Typical scenarios: Chassis connection (flange nuts are shock-resistant), drive shaft locking (slotted nuts + split pins prevent loosening), brake caliper installation (stainless steel flange nuts are resistant to brake fluid corrosion).
3.Energy, power and heavy equipment
Common types: Hot-dip galvanized hexagonal nuts, high-strength nuts
Typical scenarios: assembly of generator sets, connection of port machinery, fixation of power towers (hot-dip galvanizing for anti-corrosion), maintenance of heavy mining equipment.
4.Electronic medical equipment
Common types: Cover nuts, small stainless steel nuts
Typical scenarios: Grounding of server cabinets (conductive stainless steel nuts), packaging of medical equipment shells (dust-proof and contact-proof cover nuts), internal fixation of precision instruments (non-magnetic brass nuts).
At Yuhuang, we simplify the customization process to ensure that you get a product that perfectly matches the bolts

2.Type (such as slotted nuts, special-shaped flange nuts)
3.Dimensions (thread specifications, nut thickness, flange diameter,
Q: How to choose the scene for nuts of different materials?
A: For damp or corrosive scenarios, choose stainless steel or hot-dip galvanized nuts. For precision/non-magnetic requirements, choose brass nuts; For heavy-duty load-bearing, choose high-strength carbon steel nuts.
Q: What should I do if the nut is prone to loosening?
A: Use slotted nuts with cotter pins and flange nuts, or use spring washers and apply anaerobic adhesive.
Q: What other information is required for custom nuts?
A: Supplement the usage environment (temperature, chemical contact), force requirements, surface treatment, and special certifications (such as IATF16949).
Q: Can flange nuts replace "ordinary nuts + flat washers"?
A: Most scenarios can be replaced; When ultra-high strength load-bearing is required and elastic washers are needed, it is recommended to retain the original combination.
Q: Do nuts need to be replaced immediately if they rust?
A: Minor rust can be removed and it can still be used. Rust enters the thread, is difficult to disassemble and assemble, or in waterproof/pressure-bearing scenarios, it needs to be replaced immediately.
