the material is mostly high alloy steel or special steel, which can withstand long-term repeated loads.
-Good stability:
the structural design of the bolt prevents loosening under vibration or impact.
-Easy to install and maintain:
the bolt head design is easy to operate with tools, and is easy to check and disassemble regularly.
