1-3/4 in Combination Wrench

This Capri Tools combination wrench measures 1-3/4 inches and features a 12-point box end with WaveDrive design. It is forged from premium Chrome Vanadium steel using a 10-step heat treatment process for high-torque durability. The 15-degree offset provides knuckle clearance in tight spots. A heavy-duty canvas roll-up pouch is included for storage and transport.

Mechanics needing a single large SAE wrench

Technicians requiring a 1-3/4 inch 12-point wrench for high-torque applications will find this tool suitable. Buyers who need a full set of combination wrenches should look at a complete kit instead. Those working exclusively with metric fasteners require different sizes. The included pouch only holds this individual wrench.

12-point WaveDrive box end

The 12-point WaveDrive box end transfers torque uniformly to prevent rounding fastener corners. This geometry is the primary feature determining compatibility with damaged or stubborn bolts. The 15-degree offset angle assists access in confined areas. Chrome Vanadium construction and heat treatment ensure the wrench withstands heavy professional use.

Questions about this item

Does the 12-point WaveDrive box end need any special maintenance to keep the torque transfer smooth?

The 12-point WaveDrive box end is polished and protectively plated. No special maintenance is required beyond normal cleaning and dry storage.

What is the first limit reached when applying sustained high torque with this 1-3/4 in wrench?

The wrench is heat-treated through a 10-step process using premium Chrome Vanadium steel specifically so it does not break under high torque pressure.

How much heat does the Chrome Vanadium steel generate during all-day use in a high torque environment?

The wrench is made from premium Chrome Vanadium steel with a 10-step heat treatment. The steel itself does not generate heat; it withstands the forces applied.
