The torque value should be determined experimentally before installation. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D9YLDNFW | | Best Sellers Rank | 209,195 in DIY & Tools ( See Top 100 in DIY & Tools ) 674 in Self-tapping Screws | | Brand Name | DIYUK | | Colour | Silver | | Compatible Groove Diameter | 4.8 Millimeters | | Customer Reviews | 4.8 4.8 out of 5 stars (20) | | Drive System | External Hex | | Exterior Finish | Zinc | | Fastener Size | 50mm | | Fastener Type | Self-Drilling Screws | | Finish Types | Zinc Plated | | Grade Rating | Premium | | Head Type | Außensechskant | | Item Diameter | 4.8 Millimetres | | Item Weight | 400 Grams | | Manufacturer | DIYUK | | Manufacturer Part Number | DIN 7504K | | Material Type | Alloy Steel, Rubber, Zinc | | Metal | Alloy Steel | | Model Number | DIN 7504K | | Number Of Items | 50 | | Number of Packs | 1 | | Number of Pieces | 50 | | Outside Diameter | 4.8 Millimetres | | Screw Head Style | Hex | | Screw Point Style | Self-Drill Point | | Set Name | Roofing Screws Length: 50mm Hex Head Self-Drilling (Pack of: 50) | | Set Screw Thread Type | Coarse thread | | Size | Length: 50mm | | Thread Class | 2B | | Thread Coverage | Partially Threaded | | Thread Size | 4.8 mm | | Thread Style | Right-hand thread, coarse thread m4.8 | | Thread Type | UNC | | Unit Count | 50.0 count | ## Product Details - **Exterior finish:** Zinc - **Head style:** Hex - **Material:** Alloy Steel, Rubber, Zinc - **Point style:** Self-Drill Point - **Thread size:** 4.8 mm ## Images ![Hex Head Self-Drilling Tek Screws with EPDM Washer, Zinc Plated 4.8 x 50mm, DIN 7504-K, CE Marked, Pack of 50 - Image 1](https://m.media-amazon.com/images/I/31GSlHyM8tL.jpg) ![Hex Head Self-Drilling Tek Screws with EPDM Washer, Zinc Plated 4.8 x 50mm, DIN 7504-K, CE Marked, Pack of 50 - Image 2](https://m.media-amazon.com/images/I/41DX44KAXVL.jpg) ![Hex Head Self-Drilling Tek Screws with EPDM Washer, Zinc Plated 4.8 x 50mm, DIN 7504-K, CE Marked, Pack of 50 - Image 3](https://m.media-amazon.com/images/I/4103zaYkl7L.jpg) ![Hex Head Self-Drilling Tek Screws with EPDM Washer, Zinc Plated 4.8 x 50mm, DIN 7504-K, CE Marked, Pack of 50 - Image 4](https://m.media-amazon.com/images/I/41LpKBgk3jL.jpg) ![Hex Head Self-Drilling Tek Screws with EPDM Washer, Zinc Plated 4.8 x 50mm, DIN 7504-K, CE Marked, Pack of 50 - Image 5](https://m.media-amazon.com/images/I/41KbKgVWdOL.jpg) ## Available Options This product comes in different **Size, Item Package Quantity** options. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/806266865-hex-head-self-drilling-tek-screws-with-epdm-washer-zinc](https://www.desertcart.co.za/products/806266865-hex-head-self-drilling-tek-screws-with-epdm-washer-zinc) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-10-17*
