DIN 7982 2.5mm Diameter Countersunk Phillips/Cross Recessed Drive
Self-tapping Screws
Standardization and Quality Assurance:
DIN7982 is a German industrial standard. Choosing screws that meet
this standard means selecting products that have undergone strict
quality control and standardization. This helps ensure the quality
and performance of the screws, thereby enhancing the reliability
and safety of the overall product.
Convenient Installation Method:
- The cross-recessed design allows the screws to be easily tightened
using a regular screwdriver or power tool, improving installation
efficiency.
- The countersunk design enables the screw head to sink completely
into the material surface, maintaining a flat installation surface
while avoiding possible damage or inconvenience caused by
protruding screw heads.
Wide Applicability and Compatibility:
- DIN7982 standard screws are available in various sizes, such as
ST2.2 to ST6.3, suitable for materials of different thicknesses and
hardness, providing greater flexibility.
- Due to their self-tapping nature, these screws can be installed
directly without pre-drilling or tapping, simplifying the workflow.
Combination of Aesthetics and Practicality:
- The head of the countersunk screw does not protrude from the
installation surface, maintaining the overall aesthetics,
especially suitable for applications that require attention to
appearance.
- Simultaneously, its cross-recessed design ensures convenient and
practical operation.
Multiple Material and Surface Treatment Options:
- DIN7982 standard screws can be made of various materials, such as
stainless steel, carbon steel, etc., to meet different corrosion
resistance and strength requirements.
- Surface treatments like galvanizing or nickel plating further
enhance the screw's corrosion resistance and service life.
Application Scenarios:
- Machinery Manufacturing: Used to fix and connect various components in machinery
manufacturing and maintenance.
- Architectural Engineering: Can be used to fix boards, decorative strips, and other materials
in construction projects.
- Furniture Production: Used to connect wood or other materials during furniture
manufacturing, ensuring structural stability.
- Electronic Equipment: Used to fix circuit boards or other internal components, ensuring
stable equipment operation.
