In modern industry, machinery and manufacturing, screws are the most basic fasteners that constitute the whole. The scope of application and utility is so wide that it is impossible to summarize, covering various equipment and structures. This article aims to help users quickly understand the basic information of screws supplied by JLCMC, including types, specifications, materials, applications, and reasons for choosing JLCMC screws.

Types of screws supplied by JLCMC

Pan Head Screw: Features a slightly rounded head that distributes load evenly, commonly used in electronic devices and household appliances.

Set Screw: Headless design typically used to secure an object within or against another object, such as fixing gears or pulleys to a shaft to prevent movement.

Tapping Screw: Self-tapping screws can create threads in materials, such as wood or plastic, suitable for quick assembly and fastening.

Hex Screw: Designed with a hexagonal head, suitable for applications requiring high torque, such as heavy machinery and structural connections.

Phillips Screw: Characterized by a cross-shaped drive, allowing for quick and efficient installation, frequently used in appliances, furniture, and lightweight applications.

Thumb Screws: Equipped with a knurled head for manual tightening and loosening without tools, ideal for adjustable connections.

Flat Head Screw: Countersunk head design that sits flush with the material surface after installation, ideal for applications requiring a smooth finish, such as furniture and construction projects.

Locking Screw: Designed to prevent loosening under vibration and shock, often used in automotive and mechanical equipment.

Self-drilling Screw: Comes with a drill point that can penetrate metal and other hard materials without pre-drilling, saving time and steps, widely used in construction and metalworking.

Screw Head Types

Cylindrical Head: This type of screw head has a cylindrical shape that allows it to be mounted flush with a surface. It is often used in applications where strength and reliability are critical, such as industrial machinery and heavy equipment.

Countersunk Head: Countersunk head screws are designed to sit flush with or below the surface of the material, making them ideal for applications that require a smooth, finished look. They are widely used in construction, woodworking, and furniture assembly.

Pan Head: Pan head screws have a flat bearing surface and a slightly rounded top for a clean look and even pressure distribution. Pan head screws are often used in electrical and mechanical applications that require medium torque.

Socket Head: Also known as socket head screws, they have a cylindrical head and an internal hexagonal drive. They are used in applications that require high torque and strong clamping forces, such as engineering, automotive, and industrial applications. The design allows for deeper drive engagement, reducing the risk of slippage.

External Thread: This type is not a specific head style, but refers to screws that have exposed threads extending to the outside. Externally threaded screws can be equipped with a variety of head types and are used in situations where a long threaded grip is required for a secure hold.

Thumb Head: Thumb head screws have a ridged or knurled head that allows them to be tightened and loosened by hand without tools. They are often used in situations where frequent adjustments are required, such as fixtures, clamps, and small equipment.
