• Forged from selected alloy steel to withstand high-leverage and heavy loads.
• Extra heavy-duty head area gives maximum strength and durability.
• Continuous taper of handle makes lining-up bolt holes easy and works on a range of bolt and/or hole sizes without binding.
• Extra-large hub area works on larger-diameter holes better than other spanners.
• Catalogue number, bolt size and nominal opening size are stamped on every wrench for easy identification
