Hex Head Zinc Plated Din 7504K Self Drilling Screws 4.2mm 19mm Pack 100

The 4.2mm diameter by 19mm length variant offers an excellent mid-range option for general-purpose fastening applications where additional length is required beyond the shorter 13mm option. This size is particularly well-suited to fixing metal panels, cladding sheets, and electrical enclosures where materials need to be securely fastened with sufficient thread engagement. The 19mm length provides the perfect balance between versatility and strength, allowing secure fixing through single or double layers of sheet material. The self-drilling point cuts cleanly through metal up to 5mm thick, whilst the zinc-plated finish ensures long-term corrosion resistance. The hex head provides excellent grip for powered drivers, reducing installation time on larger projects.
