About this item
- Thread Dia.: #14 (6.3mm); Length(not include hex head): 1-1/4"(32mm); Thread Pitch: 1.8mm; Hex Head Size: 10x5.9mm / 0.39" x 0.23"(Hex WidthxT); Flange Dia.: 12mm / 0.47"; Washer Size: 16 x 3.5mm / 0.63" x 0.14"(D*T); Screw Drilling Range (Plate Thickness): 2-6mm
- Material: Both the screw and the metal washer are made of carbon steel, a zinc-plated surface finish, which is corrosion-resistant; the black washer is made of EPDM, which is wear-resistant and oxidation-resistant.
- Advantages: The hex washer head has a flange with an EPDM rubber washer on the bottom to prevent leaks, loosening and damage to mating surfaces. When you tighten the self-drilling screw, a flexible black EPDM rubber washer bonded to the metal washer creates a tight seal.
- Easy to use: Unlike self-tapping screws, these self-drilling screws drill a hole and tap a thread in one operation. All you need to install them with a power drive tool.
- Application: Hex head self-drilling screws are typically used in metal-to-metal and metal-to-wood applications. Widely used in the electrical and industry, most commonly on thin metals, for example with roofing, steel studs, etc.

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.
