DIN 7976 Hex Head Self-Tapping Screw with Blunt Point, Form F

DIN 7976 governs the manufacture of self-tapping screws with a blunt point. The fastener is installed into pre-drilled holes, and no thread cutting is required.

The special thread allows the screw to be driven into the material and fixed securely. The fastener is suitable for installation in soft metals, such as sheet aluminium, as well as for assembling plywood, hardboard and other materials. Form F features a hex head for driving with a wrench.

Materials and characteristics

The product is made of carbon steel St and may additionally be zinc-plated. Zinc coating prevents corrosion and increases resistance to environmental exposure. For conditions of higher corrosion activity, fasteners made of stainless steel A2 and A4 are used.

DIN 7976 fasteners have the following characteristics:

• The closest equivalent is manufactured to the international standard ISO 1479.
• The length of the metal shank can range from 6.5 to 70 mm.
• The size of the hex head ranges from 2.2 to 8 mm.

The fastener is in demand in construction and industry, and is used for exterior and interior finishing of buildings. It is used to fasten sheet materials to frames, including during the installation of siding or metal roofing tiles.
