Erection Wrenches
Drop-forged from select alloy steel to withstand high-leverage and heavy loads. Extra-heavy-duty head area gives maximum strength and durability. Wrench handle features an extra-deep offset to provide additional hand-clearance without sacrificing tightening power. Continuous taper of handle makes lining-up bolt holes easy, allows use on a range of bolt-hole sizes without binding. Extra-large hub area allows use on larger diameter holes than possible with most other wrenches. Available in heavy, regular and utility nut sizes. Catalog number, bolt size and nominal opening size are stamped on every wrench for easy identification. American Bridge Design.
