Types of Bi-Metal Screws

There are several types of bi-metal screws, each made for different applications. Here’s a quick overview of the most common types:

• Stitching Screw:
  Used for fastening overlapping steel plates in supporting structures. It provides a secure connection, often used in roofing and cladding applications.

• Self-Drilling Screw:
  Performs three tasks—drilling, tapping, and tightening—in one operation. It features a drill-shaped point that allows it to drill its own hole and create threads in materials like metal.

• Sandwich Panel Screw:
  Ideal for fastening sandwich panels used in roofing and wall construction.

• Fibre Cement Screw:
  Used for attaching roofing materials like fiber cement boards. These screws have sharp self-drilling points and high-strength threads, allowing easy penetration into fiber cement without cracking or damaging the material.

• Wingtek Screw:
  Features wings at the tail, which break off upon penetrating steel.
  Once the wings reach the harder material (like steel), they break off, allowing the screw to anchor securely. This makes wingtek screws ideal for multi-material connections, such as timber to steel or composite panels.

• Concrete Screw:
  It’s a heavy-duty fastener designed for anchoring objects to concrete, brick, or masonry surfaces

• Stainless-Steel Plate Screw:
  A new product by K.TICHO Industries, this screw can directly tap into stainless steel plates, which is not common in the market.
