Ampco W-673 Combination Wrench 15 3/4 in

Non-Sparking Combination Wrench

The Ampco W-673 Combination Wrench is a non-sparking, non-magnetic hand tool designed for hazardous environments. Its corrosion-resistant nickel aluminum bronze construction prevents rust and ensures long-term durability. The open and box end configuration fits SAE fasteners requiring a 1 1/8 inch head size. This wrench suits maintenance professionals in chemical, oil, gas or mining sectors.

15 3/4 Inch Length and Head Clearance

The overall length of 15 3/4 in provides mechanical advantage for loosening or tightening stubborn fasteners. The 1 1/8 inch box end fully engages the flats of compatible nuts and bolts to reduce rounding risk. Headroom is limited to the fixed SAE size, so the wrench cannot address metric or smaller SAE dimensions. Users needing multiple sizes must carry additional wrenches.

Bronze Alloy Practical Limits

The nickel aluminum bronze material resists spark generation and magnetic interference, meeting safety needs in explosive atmospheres. It also withstands corrosive agents better than standard steel alloys. The softer bronze wears faster than hardened steel under high torque, so the wrench is not intended for continuous heavy industrial fastening. It remains a specialised safety tool rather than a general-purpose mechanic's wrench.
