Types of Self Tapping Screws We Offer

Tapping Screw, Type A, Zinc CR+3

Type A tapping screws feature coarse threads and sharp points, making them effective in thin sheet metals, plastics, and wood. Their aggressive threading provides secure fastening in softer materials without pre-drilling. The zinc clear finish delivers corrosion resistance, making them dependable in light construction and appliance use.

Tapping Screw, Type B, Zinc CR+3

These screws have finer threads than Type A, allowing them to perform well in thicker metals and harder materials. The zinc plating protects against moisture and oxidation, ensuring long-lasting fastening. They are commonly used in machinery, automotive, and equipment assemblies where durability is essential.

Tapping Screw, Type AB, Zinc CR+3

Type AB screws blend features of Type A and Type B, combining sharp points with finer threads for versatility. They are effective in both thin and thicker sheet metals, making them useful for a broad range of applications. The zinc clear finish adds corrosion resistance, extending service life in appliances, construction, and equipment.

Thread Cutting Screw, Type F, Zinc CR+3

These screws cut their own machine screw threads into harder materials, providing strong, permanent fastening. The Type F blunt point reduces splitting and ensures secure thread engagement. Zinc plating provides protection from rust, making them suitable for automotive, machinery, and structural steel applications.

Thread Cutting Screw, Pan Slotted, Type F, Zinc CR+3

Pan slotted Type F screws cut clean machine threads and feature a pan head for broad bearing surface. The slotted drive allows for simple installation while providing consistent torque. Zinc clear plating resists corrosion, making these screws practical for sheet metal, equipment, and electrical projects.

Thread Cutting Screw, Type 23(T), Zinc CR+3

These screws feature a notched point that reduces driving torque and helps prevent splitting in thin materials. They are commonly used in sheet metal, composites, and plastics where reduced driving force improves efficiency. Zinc clear plating provides protection against rust and corrosion.

Thread Cutting Screw, Type 25(BT), Zinc CR+3

Type 25 screws have wider threads and a sharper point for effective cutting in plastics and soft metals. Their design reduces driving resistance, allowing faster installation. Zinc coating ensures corrosion resistance, making them suitable for industrial equipment and consumer products.

Thread Rolling Screw, Zinc CR+3 & Wax

Thread rolling screws form threads by displacing material instead of cutting it, preserving the strength of the substrate. The zinc clear finish protects against corrosion, while wax lubrication reduces driving torque. These screws are commonly used in automotive, electronics, and sheet metal work where strong, chip-free threads are important.

Metric Thread Forming Screws, 6 Lobe Pan Head, DIN 7500C, Zinc CR+3

These metric screws meet DIN 7500C standards and feature a 6 lobe drive for superior torque transfer. Their pan head distributes load evenly, while their thread forming design eliminates chips. The zinc clear coating provides corrosion resistance, making them a staple in international automotive and machinery assemblies.

Floorboard Thread Cutting Screw, Type F, Phosphate

These screws are designed specifically for fastening floorboards and wood assemblies. Their Type F cutting point ensures reliable engagement in dense wood without splitting. The phosphate finish improves lubricity during installation and provides mild corrosion resistance for interior flooring applications.

Material Options

South Coast Fasteners stocks self tapping screws in materials engineered for durability and versatility.

Low Carbon Steel

Low carbon steel is the most common material for self tapping screws, offering a balance of strength and affordability. It is widely used in sheet metal, cabinetry, and woodworking applications. Its machinability ensures reliable thread forming and consistent installation.

Alloy Steel

Alloy steel provides higher strength and toughness than low carbon steel, making it ideal for demanding applications. It is commonly used in automotive, heavy equipment, and structural assemblies where durability is critical. The added alloying elements increase wear resistance and load capacity.

Stainless Steel (Optional Lines Not Shown Here)

In many industries, stainless steel versions of self tapping screws are used for marine and chemical applications. Stainless steel provides exceptional corrosion resistance, making it the material of choice where moisture or harsh substances are present. Its strength and non-magnetic properties further extend its usefulness.

Available Finishes

South Coast Fasteners offers self tapping screws in finishes that protect against corrosion and improve installation performance.

Zinc Clear CR+3

Zinc clear plating provides a clean metallic look while protecting against rust. It is widely used in automotive, machinery, and construction applications. This finish is reliable for both indoor and light outdoor use where protection and appearance are important.

Wax Coating

Wax is often applied in combination with zinc plating to reduce installation torque and extend tool life. It improves efficiency in production environments and ensures consistent seating of the screw. Wax coatings also add a layer of moisture resistance for added protection.

Phosphate

Phosphate coatings deliver mild corrosion resistance along with lubricity, making screws easier to drive. They are often used in woodworking and flooring applications where smooth installation is critical. The dark finish also provides a clean, low-reflective appearance.
