DIN7504M 410 Stainless Steel Self Drilling Tail Screws

DIN 7504M 410 Stainless Steel Self Drilling Tail Screws in ST5.5×25 are large-diameter, heavy-gauge drill-point fasteners designed for connecting steel purlins, structural steel sections, and thick-gauge cladding sheets in industrial buildings, warehouses, and steel-framed structures. The ST5.5 outer diameter and 25mm length provide the thread engagement needed for connections through thicker base materials — such as C and Z purlins, RHS structural sections, and built-up roofing assemblies.
