DIN 7500 Taptite Thread-Forming Screw (Self-Tapping), Form D

The DIN 7500 European standard governs the production of steel thread-forming screws of the Taptite series. These belong to the category of self-tapping screws that do not require pre-tapped holes.

During installation, the special thread cuts into the material, ensuring a secure fastening in the hole. The Form D screw features a hex head designed for tightening with a wrench of the matching size. This type of fastener is suitable for use with various sheet materials, including metal and plastic.

Manufacturing and application features

Screws manufactured to the DIN 7500 standard are made from high-strength carbon steel; for corrosion resistance, the metal can be given a zinc or nickel coating. Fasteners made from A2 and A4 stainless steel are also common and can be used in highly corrosive environments. The metal is selected according to the specific application and purpose of the fastener.

Products of this type have the following set of characteristics:

• Nominal thread diameter ranges from M2 to M8.
• The special TRILOBULAR thread shape reduces friction during driving, resulting in the strongest possible fixation.
• When driven in, the fastener forms a right-hand metric thread with a 0.5 mm pitch.

This series of fasteners is widely used in construction and building finishing. The products are used to fasten siding, metal roofing, profiled sheeting, and are also used in steel structure assembly and for attaching sheet materials to frames. The special thread and distinctive head shape simplify and speed up installation.
