DIN 7516 E Self-Tapping Screw with a Countersunk Head
Technical Characteristics of DIN 7516 E
DIN 7516 E is a self-tapping screw with a countersunk head, designed to create secure connections in metal without the need for pre-cut threads. The main feature of this screw is its ability to form a threaded connection independently during screwing.
Key characteristics:
- Head type: Countersunk, ensuring a smooth surface after installation.
- Thread type: Self-tapping, allowing for reliable connections without additional threading tools.
- Material: Carbon steel or stainless steel.
- Coating: Zinc plating, nickel plating, or phosphating for corrosion protection.
- Purpose: Fastening metal elements, joining structures, mounting cladding panels.
DIN 7516 E screws are widely used in mechanical engineering, the automotive industry, and construction due to their high strength and ease of installation.
Strength Class of DIN 7516 E Self-Tapping Screw with a Countersunk Head
The strength class of DIN 7516 E screws depends on the material of manufacture. The main strength options include:
- Carbon steel 4.8, 5.8, 8.8 – Standard strength for medium-load applications.
- Stainless steel A2, A4 – High corrosion resistance, suitable for use in humid conditions.
- Zinc-coated steel – Additional protection against corrosion, extending the lifespan of the fastener.
The choice of strength class depends on operating conditions and the required load-bearing capacity of the fastening.
Fastener Group of DIN 7516 E
DIN 7516 E belongs to the group of self-tapping screws used to create threaded connections without pre-cutting threads in the material. Features of this fastener group include:
- Used for metal installation without additional operations.
- High strength and resistance to vibration loads.
- Ensures even load distribution due to the countersunk head.
These screws are used where quick and reliable fastening is needed without additional thread-cutting tools.
Manufacturing Materials of DIN 7516 E Self-Tapping Screw with a Countersunk Head
DIN 7516 E screws are made from various materials depending on operating conditions and required strength. The main materials include:
- Carbon steel – The most common option, providing good mechanical strength.
- Stainless steel (A2, A4) – Used in humid and aggressive environments, does not require additional coating.
- Zinc-coated steel – The protective coating prevents corrosion, making the screws suitable for use in wet conditions.
The choice of material depends on the application. Carbon steel is sufficient for standard structures, while stainless steel is recommended for aggressive environments.
Application of DIN 7516 E
DIN 7516 E screws are widely used in various industries and construction sectors due to their technical characteristics.
Main application areas:
- Automotive industry – Fastening metal parts, mounting body elements and internal structures.
- Construction – Used for cladding panel installation and joining metal structures.
- Mechanical engineering – Applied in the production of industrial equipment and mechanisms.
- Electronics – Used for assembling electronic device housings, ensuring secure fastening.
Installation of DIN 7516 E screws is performed using a screwdriver or power drill. Thanks to the self-tapping thread, the fastening process is simplified and does not require pre-drilled holes.
The application area also depends on the manufacturing material:
- Zinc-coated steel – Provides additional corrosion protection, important for use in wet and aggressive environments.
- Stainless steel A2 – Corrosion-resistant, suitable for environments with temperature fluctuations and high humidity.
Due to their technical characteristics, DIN 7516 E self-tapping screws are an effective solution for many industries and construction applications
