Screws

A screw is a long metal rod with threads on its surface. Screws are usually used together with nuts to connect two objects by turning the nut. Screws come in many different types and sizes, such as wood screws, self-tapping screws, machine screws, and more.

Threaded rod

A threaded rod is a long metal rod with threads on its surface, usually used to connect and support structural members, fix objects, etc. Unlike screws and screws, a threaded rod has no head and its ends can be attached and secured with nuts or other fasteners. It is usually made of carbon steel, alloy steel, stainless steel, etc., and can be surface treated to improve its corrosion resistance and wear resistance. Common surface treatment methods include galvanizing, chrome plating, phosphorylation, etc.

Flat washer

It is usually used to disperse the pressure of fasteners, reduce wear and friction, adjust the size of fasteners, etc. The flat washer has high elasticity and toughness, and can be deformed under the pressure of the fastener to achieve the effect of reducing pressure and absorbing shock.

The material of the flat washer is usually carbon steel, stainless steel, copper, aluminum and other metals or non-metallic materials such as plastic and rubber. Flat washers of different materials have different characteristics and uses. For example, stainless steel flat washers have the characteristics of good corrosion resistance and long service life, and copper flat washers have the characteristics of good electrical conductivity and high temperature resistance.

Nuts

It is usually used in conjunction with fasteners such as screws and threaded rods to achieve the effect of connecting and fixing objects. The function of the nut is to adjust the length of the threaded rod or screw by cooperating with the thread, and increase the tensile strength and bearing capacity of the fastener to ensure the stability and reliability of the connection.

There are many types of nuts, common ones are hexagonal nuts, round nuts, square nuts, lock nuts and so on. Nuts are usually made of carbon steel, stainless steel, copper, aluminum and other metals. Nuts of different materials have different characteristics and uses. For example, stainless steel nuts have good corrosion resistance and long service life. High temperature and other characteristics.

Industry Knowledge

What are metal screws and how do they differ from other types of screws?
Metal screws are fasteners designed specifically for use with metal materials. They are commonly used in various industries, construction projects, automotive applications, electronics, and more. Here's how metal screws differ from other types of screws:
Material: Metal screws are primarily made of metal alloys such as steel, stainless steel, brass, or aluminum. This distinguishes them from screws made of other materials like plastic or wood.
Strength and Durability: Metal screws are generally stronger and more durable compared to screws made of non-metallic materials. They can withstand higher levels of tension, shear forces, and torque without breaking or deforming.
Thread Design: Metal screws often have a specific thread design optimized for use in metal materials. These threads are typically sharp and self-tapping, allowing the screw to cut into the metal and create a secure and tight connection.
Corrosion Resistance: Depending on the material chosen, metal screws can offer varying levels of corrosion resistance. Stainless steel screws, for example, have excellent corrosion resistance, making them suitable for outdoor or high-moisture environments.
Head and Drive Types: Metal screws are available in various head types (e.g., flat head, pan head, hex head) and drive types (e.g., Phillips, slotted, Torx) to accommodate different applications and installation methods.
Load-Bearing Capacity: Due to their strength and structural integrity, metal screws are capable of bearing heavier loads compared to screws made of weaker materials. They are often used in applications where secure and robust fastening is essential.
Compatibility: While metal screws are designed specifically for use with metal materials, they can also be used in conjunction with other materials such as wood, plastic, or composite materials, depending on the specific screw design and application requirements.
What are the different types of metal screws available?
There are various types of metal screws available, each designed for specific applications and requirements. Here are some common types of metal screws:
Machine Screws: Machine screws are typically small-diameter screws with a straight, cylindrical shank and a flat or rounded head. They are often used with threaded nuts or tapped holes and are commonly found in machinery, appliances, and electronic devices.
Self-Tapping Screws: Self-tapping screws have a sharp, self-drilling point and specially designed threads that allow them to cut into and tap their own holes in metal materials. They eliminate the need for pre-drilling and are commonly used in metal-to-metal fastening applications.
Sheet Metal Screws: Sheet metal screws have sharp, self-tapping threads and a flat or pan head. They are designed specifically for fastening thin metal sheets or panels together, as well as attaching metal to other materials like wood or plastic.
Wood Screws with Metal Threads: Wood screws with metal threads, also known as dual-purpose or dual-thread screws, have a wood screw-like body with a pointed tip and metal threads. They are designed to securely fasten metal to wood or composite materials.
Socket Head Cap Screws: Socket head cap screws have a cylindrical head with a recessed hex socket (internal wrenching feature) for installation. They provide a smooth, low-profile appearance and are commonly used in machinery, equipment, and automotive applications.
Set Screws: Set screws are fully threaded screws without a head. They are typically used to secure one object within or against another, often using an Allen wrench or hex key to tighten them. Set screws are commonly used in machine parts, shafts, and collars.
Lag Screws: Lag screws, also known as lag bolts, are heavy-duty screws with a hexagonal head and coarse threads. They are used for fastening heavy objects to wood or metal surfaces and are commonly used in construction, woodworking, and outdoor applications.
