FEATURES:€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) has patented locking grooves that help prevent the wrench from slipping off the fastener when turning. €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 will be available. €Typically used in lower torque applications. €Full Polish finish provides corrosion resistance and easy to clean surfaces. €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's arm or where the fastener is out of site. €Locking hole on 3/8" drive crowfoot wrenches available on fractional openings 1" and larger.
