ISO 7380-2 defines the specifications and performance requirements for hexagon socket button head flange screws. These screws are widely used in industrial manufacturing, automotive, mechanical, and electronic fields due to their unique design and reliable performance. This article provides a detailed introduction to the usage and application scenarios of ISO 7380-2 screws.

Usage of ISO 7380-2 Hexagon Socket Button Head Flange Screws
1. Tool Selection
The head of ISO 7380-2 screws features a hexagon socket, requiring a hex key or power tool for installation. Select a tool size that matches the hex socket of the screw head to avoid damaging the head during installation.
2. Preparation Before Installation
Before installing ISO 7380-2 screws, ensure the precision of the threaded hole. Since the screw has a flange (washer face), the installation hole should be a straight hole without a countersink. If the screw head needs to be flush with the installation surface, a washer can be used for adjustment.
3. Installation Steps
Align the screw with the hole, ensuring it is perpendicular to the installation surface.
Insert the hex key or power tool gently into the hex socket of the screw head and rotate evenly until the screw is fully tightened.
If using a power tool, pay attention to controlling the tightening torque to avoid damaging the screw or the installed component due to excessive tightening.

4. Notes for Attention
Keep the tool perpendicular to the screw head during installation to prevent slipping or damage to the head.
For applications requiring repeated disassembly, consider using high-strength and corrosion-resistant materials, such as stainless steel.
Regularly inspect installed screws to ensure they have not loosened due to vibration or other external forces.
