Screw Nail

Screw Nail

Screw nails are a common fastener that comes in many types and specifications, including wood screws, self-tapping screws, self-drilling screws, etc. They are widely used to firmly fasten metal, plastic, and wood. The core feature of a screw nail is its thread design, which can be screwed into the material by rotation to form a strong connection and gripping force.

Our company produces screw nail making machines that can produce a variety of screw nails to meet different fastening needs. During the production process, we focus on the balance between price and quality and strive to provide customers with the most cost-effective screw nails.

Screw Nail Structure

A screw nail consists of a screw shank, a head, and a tip. The screw shaft is surrounded by a spiral thread, which is usually divided into coarse and fine thread, suitable for soft and hard materials respectively. The head of a screw nail has a variety of shapes, such as countersunk and flat heads. Countersunk screws are flush with the material surface after being screwed in and are suitable for applications that require a flat surface. Round head screws are ideal for occasions where the material does not need to be fully embedded. The groove type of the head determines the type of tool used. Common groove types include Phillip, slots, and hexagons. The screw tip is usually designed to be pointed, which makes it easy for the screw nail to enter the material and fix it quickly.

Types of Screw Nails

• Wood Screw Nail

Wood screws are designed for wood and usually have thicker threads and sharp tips that form a strong connection in the wood and prevent loosening. Wood screws are widely used in furniture assembly, woodworking construction, and home decoration, such as installing shelves, repairing wooden fences, or building decks.

• Self-Tapping Screw Nail

Self-tapping screws have sharp threads that can cut threads in materials that do not have pre-threads and form a strong threaded connection. They suit metal, plastic, and wood, especially in quick installation situations. Self-tapping screws are often used in electronic equipment, automotive assembly, and architectural metal structures.

• Self-Drilling Screw Nail

The tip of a self-drilling screw is designed in the shape of a drill bit, which can directly drill holes and form threads in hard materials, eliminating the step of pre-drilling. Self-drilling screws are particularly suitable for construction projects, such as metal roofing, steel structure installation, and other applications that require a strong connection to be formed quickly on metal.

How To Choose Screw Nails

Choosing the right screw nail requires considering the material type, the screw nail size, and the user environment. For different materials (such as wood, metal, or plastic), choose the corresponding screw type and thread type. The material thickness and the required connection strength determine the screw nail diameter and length. In addition, if the screw nail is used outdoors or in a humid environment, choosing galvanized or stainless steel screw nail is critical to ensuring durability.

How To Install Screw Nails Effectively

When installing screw nails, it is essential to choose the right tools. Choose the manual or electric screwdriver according to the groove type of the screw. For harder or thicker materials, you can use an electric drill to pre-drill holes first to avoid cracking the material and ensure that the screw nails are screwed in smoothly. When installing, keep the screw nails perpendicular to the material surface, apply force evenly, and avoid over-tightening to cause damage to the screw nails or materials. After installation, check whether the screw nails are firm and make fine adjustments if necessary.
