Self‑drilling screw for sheet metal and steel with hex head

The 4.8 × 19 mm screw with a hex head and integrated washer is designed for fastening elements to sheet metal and steel structures without the need for pre‑drilling a hole. A special drilling point at the tip of the thread allows self‑punching of sheet up to 6 mm thick — just place it on the surface and tighten, without additional tools or preparation.

It operates safely and efficiently even in thin sheets, and the integrated washer distributes the load, preventing material crushing under the screw. This is especially useful for installing ventilation, thermal insulation, ducts or enclosures — wherever a quick and solid metal fastening is required.

The CNBOP certificate confirms its compliance with Polish requirements for fastening elements in construction. No special skills are needed — the installer can use it like a regular screw, but with the added drilling function. It works both with manual and powered installation methods.

The 4.8 × 19 mm version is an optimal choice for medium‑thickness sheets — it is not too long to lose precision, nor too short to provide insufficient grip. Compared with the 4.8 × 16 mm screws (available in the range), this version offers a slightly longer thread reach, meaning better stability under higher loads.

Available in packs of 250 pieces — ideal for both small DIY jobs and large production series.
