Tapping Screws  Manufacturers, Traders, Suppliers

Tapping screws, sometimes referred to as self-tapping screws, are designed to create their own mating threads when they are driven into the material. Here are some key technical data points and specifications for tapping screws:

Material:

• Generally made of steel, stainless steel, or sometimes brass.
• Surface treated (e.g., zinc plating, black oxide) to enhance corrosion resistance.

Thread Design:

• The thread can vary in design, common types include:
  • Coarse threads for softer materials.
  • Fine threads for harder materials.
• Some are designed with a self-tapping feature that allows cutting of threads in metal, plastics, or wood.

Head Types:

• Common head types include:
  • Pan head
  • Flat head
  • Hex head
  • Truss head
  • Binding head

Drive Types:

• Various drive types such as:
  • Phillips
  • Slotted
  • Torx
  • Hex

Size and Length:

• Available in various lengths (from short to long depending on application) and diameters (measured in gauge or standard millimeters).

Application:

• Used in a wide range of applications, from furniture assembly to construction.
• Often used in environments where a secure fastening is critical.

Performance Specifications:

• Shear strength and tensile strength ratings can vary widely based on the steel alloy used and the screw design.
• Some tapping screws may also have specific torque requirements.

Standards and Classifications:

• Various standards exist for tapping screws, including ASTM, ISO, and DIN classifications which specify dimensions, materials, and mechanical properties.

Understanding the specific requirements for the application at hand, such as material type, environmental conditions, and load-bearing needs, is crucial when selecting the appropriate tapping screw.

More than 50,000 products. DV-supported stock-keeping. Special parts produced on order.
Our portfolio is already vast with its more than 50,000 standard fasteners- good to know that our online catalogue and our employees‘ know-how keep the overview. But since norms cannot meet all requirements, our programme of products goes beyond DIN data sheets and factory recommendations: special productions according to drawings- from the special type of screws to the plate bending part- complete our offer. We have our own innovations in our programme of products as well. One of our specialties are magnetic plug systems.
They collect the abrasion in gearbox cases or serve as a specially constructed fuel level plunger in wind power stations. In addition we have been involved in further developments of suspension arrangements in the field of mining and tunnel construction. Besides we offer extended screws for which there was a special annex to the DIN norms for the open line construction. A cleverly devised and software-supported stock-keeping and assignment sale make sure that our products are also delivered to you as soon as possible and in a perfectly compiled manner.
