Product information
DIN 7981 covers self-tapping screws with a round head, intended for fastening into thin sheet metal, plastic or other softer bases without a pre-cut thread. By type, they can have a tapered end (type C) or a flat end (type F), depending on the application. The screws have a cross recess (PH, PZ) or a TX (Torx) recess, which ensures good torque transmission and safe driving. During installation they form a thread in the base, so the connection becomes firm and sealed. Suitable for use in metal structures, electrical engineering products, household appliances and various industrial equipment. Made of carbon steel or stainless steel, often zinc-plated, so they are resistant to corrosion and environmental exposure.
