High-quality 12 No. self-tapping screws, ideal for creating their own threads in various materials, ensuring strong and secure fastenings for agricultural and general-purpose applications.
Self-Tapping Screws 12 No.
Agricart offers durable and versatile 12 No. self-tapping screws, designed for efficient and reliable fastening without the need for pre-drilled holes in many applications. These screws feature a sharp, pointed tip and a hardened thread that allows them to cut their own mating thread when driven into materials like wood, plastic, and thin sheet metal. Their robust construction ensures a firm grip and long-lasting hold, making them indispensable for a wide range of tasks from farm equipment repair to construction projects.
Select the appropriate screw length for your material thickness. Use a power drill or screwdriver with the correct bit size. Apply steady, even pressure while driving the screw to ensure proper thread formation and prevent stripping. For harder materials, a pilot hole slightly smaller than the screw's core diameter may be beneficial.
Eliminates the need for pre-drilling in many materials, saving time and effort. Provides a strong, secure, and vibration-resistant fastening. Versatile for use in various materials including wood, plastic, and light metals. Reduces assembly time and labor costs. Durable and resistant to loosening over time.
Do not overtighten screws, as this can strip the threads or damage the material. Wear appropriate safety glasses to protect against flying debris. Ensure the correct bit size is used to prevent cam-out and damage to the screw head. Not suitable for heavy-duty structural applications without proper engineering assessment.
Consider the material you'll be fastening and its thickness. Choose the appropriate screw length and head type (e.g., pan head, flat head) for your specific application. For outdoor or corrosive environments, opt for screws with enhanced corrosion resistance. Check the quantity required for your project to ensure you have enough.
Standard customs procedures apply for screws of base metal. Ensure accurate declaration of material composition and quantity.
Importation of self-tapping screws is generally straightforward. Compliance with standard import regulations and quality certifications is advised. Check for any specific duties or taxes applicable to fasteners in Pakistan.
For export, ensure packaging meets international shipping standards. Provide all necessary documentation, including country of origin and material safety data sheets if required by the destination country.

- What does '12 No.' mean for self-tapping screws?
- '12 No.' refers to the screw's nominal diameter, which is a standard sizing convention. A higher number generally indicates a larger diameter screw.
- Can these screws be used in metal?
- Yes, these 12 No. self-tapping screws are suitable for use in thin sheet metal, as well as wood and plastic. For thicker or harder metals, specific metal self-drilling screws might be more appropriate.
- Do I need to pre-drill a hole for these screws?
- In many softer materials like wood and plastic, pre-drilling is not necessary as the screw is designed to tap its own thread. For harder materials or to prevent splitting, a small pilot hole is recommended.
- What type of drive is typically used for these screws?
- Self-tapping screws commonly feature Phillips, Pozi, or Torx drives. Always match your screwdriver bit to the screw head type to ensure a secure fit and prevent damage.
- Are these screws rust-resistant?
- Our standard 12 No. self-tapping screws often come with a zinc plating for basic corrosion resistance. For outdoor or highly corrosive environments, we recommend selecting screws specifically designed for enhanced rust resistance, such as stainless steel or specially coated options.
