Self-Drilling Screw-Hex Head-DIN7504K

Self-drilling screw-hex heads are durable fasteners that combine the stability of a hexagonal head with the advantages of self-drilling. Due to their drill-like point design, these screws save time and ease installation by making their own hole in metal or other hard surfaces without the need for pre-drilling. Applying force and achieving a tight, secure fit is made easier by the hex head's greater driving surface, which increases torque. Together with other characteristics, the drill point's ability to cut through steel or sheet metal makes it the perfect tool for glazing, curtainwall, and HVAC installations.
