SP Tools patented Quad Drive open-end offers 4 times the gripping power of a standard ROE wrench by wrapping around the fastener and maximizing the contact on the flat sides of the fastener head, not the points.
The ring end features dual flat drive ring ends, making them the perfect wrench for getting to and loosening those tricky, hard-to-reach, often worn fasteners by increasing the contact area with the nut or bolt head.
Chrome Vanadium Steel (Cr-V) for high strength & durability
Meets & exceeds international ANSI & DIN standard
