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

The European standard DIN 7500 covers thread-forming screws of the Taptite series. They differ from other types of fasteners in that no pre-tapped thread is required for installation — they cut their own thread as they are driven into the material.

Thanks to the special TRILOBULAR thread form, friction during thread-cutting is minimized, which ensures secure fastening in the material. Form M features a countersunk head for full recess into the material — it does not protrude above the surface.

Material and characteristics

This type of fastener is made of carbon steel, which may additionally be coated with zinc for corrosion resistance. Stainless steel may also be used for manufacturing. The fasteners have the following characteristics:

• The head is fitted with a cross recess for driving with a hand tool or a power screwdriver.
• The nominal thread diameter ranges from M2 to M10.
• The metal shank carries a metric thread with a pitch of 0.5 mm.

The main advantage of this fastener is fast installation, as no thread needs to be tapped in the hole in the material. This speeds up the work; the fastener is used in construction, exterior and interior finishing of buildings. It is suitable for installing various sheet materials and fastening them to frames, as well as for assembling metal structures.
