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.\u003cbr\u003e2. 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. The underside of the hex head provides a large flat bearing surface that reduces the possibility of crushing mating surfaces. When you tighten the screw, a flexible black EPDM rubber washer bonded to the metal washer creates a tight seal.\u003cbr\u003e3. 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.\u003cbr\u003e4. 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.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSpecification:\u003c\/strong\u003e\u003cbr\u003eMaterial: Carbon Steel\u003cbr\u003eSurface Treatment: Zinc Plated\u003cbr\u003ePerformance Grade: 10.9\u003cbr\u003eThread Dia.: #12 (5.5mm)\u003cbr\u003eLength(not include hex head): 3\/4\"(19mm)\u003cbr\u003eThread Pitch: 1.8mm\u003cbr\u003eHex Head Size: 8x5.4mm \/ 0.31\" x 0.21\"(Hex WidthxT)\u003cbr\u003eFlange Dia.: 11mm \/ 0.43\"\u003cbr\u003eWasher Size: 16 x 3.5mm \/ 0.63\" x 0.14\"(D*T)\u003cbr\u003eScrew Drilling Range (Plate Thickness): 1.75-5.25mm\u003cbr\u003ePackage Content: 25pcs x Hex Head Self-drilling Screws","brand":"uxcell","offers":[{"title":"Default Title","offer_id":44917171978489,"sku":"a22110200ux0012","price":8.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/2477\/6095\/files\/ux_a22110200ux0012_ux_g03.jpg?v=1769763857","url":"https:\/\/www.harfington.com\/en-gb\/products\/p-1372892","provider":"Harfington","version":"1.0","type":"link"}
