What are hexagonal inserts?
A hexagonal insert is a fastener product used to enhance the strength of internal threads. It is installed in aluminum, plastic, wood, or other softer materials to create a more stable and durable internal thread structure.
Compared to ordinary threaded structures, it offers the following advantages:
· Stronger thread-locking ability
· Better anti-loosening effect
· Higher corrosion resistance
· Longer service life
· More stable repeated assembly and disassembly performance
The hexagonal structure provides stronger anti-rotation capability during installation, thus exhibiting greater stability in vibration environments or long-term use environments.
