ASME B107.21
For lower torque applications
  • Crowfoot wrenches are used in hard-to-reach, restricted access situations where a standard wrench or ratchet cannot reach
  • Anti-slip design open end (ASD)
  • The arched surfaces are designed to spread the contact forces over a greater area and they keep the loads off the corners of the fastener which helps prevent fastener rounding
  • Broad size range ensures the right tool for the application
  • Full polish finish provides corrosion resistance and easy-to-clean surfaces
  • Has patented locking grooves that help prevent the wrench from slipping off the fastener when turning
  • Locking hole feature helps keep the crowfoot wrench engaged on the extension during use reducing downtime due to detachment of crowfoot in awkward spaces
  • Use with locking extensions to reach into spaces too small for a mechanic arm or where the fastener is out of site
  • 12 point allows for fine indexing
  • Helping to improve speed and access
  • Fits 4, 6 and 12 point fasteners
