Why are pull grooves on fastener pintail stripping during the pull circle with CRRC MS-BT20?
- K
  Kimberly ChambersAug 3, 2025
  If the pull grooves on the fastener pintail are stripping during the pull cycle when using CRRC Tools, it could be due to several reasons. Make sure the anvil is completely slid onto the fastener pintail, as described in section 3.4. Also, verify that you are using the correct fastener grip; if not, replace it with the proper rivet. Other potential causes include worn or damaged jaw segments (replace the clamping jaws), foreign debris in the jaw grooves (clean the jaws), excessive sheet gap (correct the gap), or excessive pull pressure (adjust the pull pressure).

  If CRRC Tools operate erratically and fail to install the fastener properly, it may be due to low or erratic hydraulic pressure or air in the system, in this case consult the Manual of hydraulic unit. Another reason may be a damaged or worn Piston O-ring in the tool, in this case replace the O-ring. Alternatively, there could be excessive wear on the sliding surfaces of tool parts or on the internal cylinder surfaces, which requires replacing the cylinder or parts.
