About this item
  • High-Quality Material:The self-tapping screws are made of high-quality 410 stainless steel, which is harder than 304 stainless steel and offers higher tensile strength. These self-tapping sheet metal screws provide excellent corrosion resistance, rust protection, and oxidation resistance, making them ideal for long-lasting applications in various environments.
  • Self-Drilling Design:These self-tapping screws are made of metal and feature a drilling tip that allows easy penetration of materials like aluminum or metal plates without the need for pre-drilling. The flat cross-slot design ensures that the screws do not deform or slip during use.
  • Easy Installation:The countersunk cross-recess design facilitates precise positioning and easy handling. Deep threading ensures strong fastening across diverse materials. These screws effortlessly penetrate aluminum and metal sheets, enabling swift and straightforward installation.
  • Versatile Application:Countersunk screws are suitable for metal, wood, plastic, and soft metals. Self-drilling screws for steel are ideal for construction, furniture assembly, woodworking, and DIY projects, providing a stable connection between wood and metal.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
