  ANSI B18.2.1 bolts For steel structures connected by ANSI B18.2.1 bolts, the quality of the ANSI B18.2.1 bolt friction surface and the protection before installation must be paid attention to when manufacturing, and every two thousand tons, An ANSI B18.2.1 bolt friction surface of each specification and each process is tested for anti-slip coefficient.
  The steel structure installation unit must protect the friction surface to prevent pollution and corrosion before installing ANSI B18.2.1 bolt friction. Prior to installation, the ANSI B18.2.1 bolt friction surface is tested for anti-slip coefficient, check the ANSI B18.2.1 bolt factory confirmation, batch number, and periodically pull the ANSI B18.2.1 bolt of different batch numbers for axial force test.
  Non-standard Bolt is strictly controlled and inspected, and the torque wrench for screwing shall be calibrated.
  ANSI B18.2.1 bolt is a high-strength bolt, which is a standard part.
  ANSI B18.2.1 bolts are mainly used in steel structure engineering to connect the connection points of steel structural steel plates.
