• SP Tools patented Quad Drive open end offers 4 times the gripping power of a standard ROE spanner by wrapping around the fastener and maximising 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 spanner 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
