About this item
- High-quality Material - Our self drilling screws are crafted from premium 410 stainless steel, offering superior tensile strength compared to 304 stainless steel. These self-tapping screws are robust, durable, and provide excellent resistance to corrosion, rust, and oxidation.
- Self Drilling Design - The self-tapping metal screws feature a sharp self-drilling tail, allowing easy penetration into aluminum or metal plates without the need for pre-drilling. The flat head cross design ensures no deformation or slipping during use.
- Wide Application - These screws are versatile, capable of drilling, tapping, and locking materials simultaneously. They are ideal for a wide range of applications, including fixing metal plates, soundproofing materials, thermal insulation, and more to building structures. Whether you need to decorate walls, ceilings, and floors, or install lamps, shelves, wardrobes, and more, these screws are the perfect solution.
- Easy to Install - Our dome head screws ensure a strong connection and resistance to head breakage. The clear and fine thread provides high pull-out resistance, and the sharp pointed tail ensures easy penetration without the need for pre-drilling.
- Packaging Content - Each package includes 50 pieces of M4.2x38mm self-tapping screws. And three additional sizes (M4.2x16, M4.2x19, and M4.2x32) are available to accommodate diverse project requirements.

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.
