Overview

The Sunex 9720A is a wrench measuring 10.62 inches long and weighing 3.95 pounds, with a listed capacity of 1.38 inches. That combination of length and mass points to a heavy duty tool built for larger fasteners rather than light general use.

A near 4 pound weight on a wrench just over 10 inches long is substantial, well beyond a typical combination or adjustable wrench of that length, which suggests either a solid forged head or a specialty design like a striking or pipe style wrench. The 1.38 inch capacity figure likely describes jaw opening or drive size, though the listing does not specify which, so confirm the exact fastener size before buying.

  • 10.62 inch overall length
  • 1.38 inch listed capacity
  • Sunex branded heavy duty wrench

Who it's for

Mechanics and tradespeople working on larger fasteners who need extra leverage and mass in a single tool. Not the right pick for light electronics or small fastener work.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out
  • Heavy 3.95 pound build suited to high torque work
  • 10.62 inch length gives extra leverage
What to check first
  • Listing does not clarify whether 1.38 inches is jaw opening or drive size
  • Weight makes it less convenient for light or overhead work

Performance notes

The added weight relative to its length suggests a solid forged construction, which typically holds up better under high torque loads than a lighter stamped design.
