Different Types of Nails
Nails are common metal fasteners that are important in industrial production and construction. From woodworking assembly to concrete fixing, roof installation to furniture assembly, different types of nails meet diverse application needs according to their characteristics. The manufacture of nails is inseparable from efficient wire drawing machines and nail-making equipment, which determine the specifications, performance, and final application effects of nails. This article will comprehensively introduce the common types of nails and their uses to help you understand their characteristics and practical applications.
Nail Types and Characteristics
Common Wire Nails
Also known as iron nails, the most basic type of nails. Made of low-carbon wire rods (Q195/Q235), their common sizes range from 1 inch to 6 inches. Common nails have a simple production process and low cost and are widely used in woodworking, furniture manufacturing, and frame construction.
Coil Nails
By welding multiple nails to copper-coated welding wire at a certain spacing and angle (usually 15-16 degrees) to form a coil, it is necessary to use a coil nailer to facilitate workers to perform nailing operations quickly and continuously during construction. Coil nails mainly include small coil nails, large coil nails, jumbo coil nails, and conical coil nails. The types of nail shanks include smooth, ring, and screw shanks. Coil nails are widely used in pallet manufacturing, wooden box assembly, and roof construction, and are the preferred tools for industrial operations.
Roofing Nails
Umbrella heads, short and thick nail shanks. The nail shank designs include smooth, ring, screw shanks, etc. Umbrella head roofing nails are mainly used to fix corrugated tiles and light steel structures, performing well in roof installation and protection projects. Their strong grip can effectively prevent tiles from sliding or falling off.
Double Head Nails
The duplex-headed design makes them an indispensable fastener in temporary construction projects. The main head allows the nail to be driven into the surface, while the secondary head remains exposed for easy extraction when needed. This design makes it suitable for scenes that require frequent disassembly and assembly, such as building formwork splicing and temporary support frame construction.
Clout Nails
Clout nails have larger and flatter heads and thicker shanks, relatively short in length. They are usually galvanized and coated with a protective coating to prevent corrosion. The diameter of big cap nails usually ranges from 2.95 mm to 3.05 mm, and the length is about 30 mm. They are suitable for fixing soft materials such as tarpaulins, waterproof membranes, plastic films, etc., and are particularly suitable for outdoor or temporary construction.
U Nails
U-shaped nails, also known as turf nails, are a type of fastener with a U-shaped design. The materials are mostly cold-drawn wire, galvanized steel wire, or stainless steel wire. The wire diameter of the U-shaped nail ranges from 2 mm to 5 mm, the width is 2 cm to 10 cm, and the leg length is 5 cm to 50 cm. It is a common tool in agriculture and gardening projects, such as the fixing of cables, metal mesh, artificial turf and agricultural fences, etc.
Concrete Nails
Concrete nails are usually made of 65#, 55#, or 45# high carbon steel. After heat treatment, they have extremely high hardness and toughness. It can be driven into the surface of concrete or masonry without cracking or breaking. Concrete nails are the core fastener in concrete wall fixing, line laying, and heavy load construction.
Screw Nails
Screw nails are a type of nail with a relatively complex manufacturing process, including wood screws and drywall screws. Screw nails have sharp tips and large pitches, providing strong fixing force through thread design. It is suitable for furniture assembly, mechanical equipment installation, and metal-to-wood connection, and is a core fastener for high-strength fixing.
Whether simple common wire nails or complex screw nails, the diversity of nails meets the needs of all walks of life. Efficient wire drawing machines and nail making equipment are the core of manufacturing high-quality nails.
The Nail Production Process
The production of nails begins with the drawing process of steel wire. The wire drawing machine cold-draws low-carbon wire rods (such as Q195/Q235) into steel wire that meets the specifications. Subsequently, the nail-making machine cuts and heads the steel wire according to the type of nail. Some special nails, such as concrete nails and screw nails, also need to undergo heat treatment or surface treatment to enhance their hardness and corrosion resistance. The efficiency and precision of the wire drawing machine and nail-making equipment directly affect the nails’ quality, performance, and market demand.
