In the 20th century, wrench technology leaps forward. Professionals now demand tools that offer precision and versatility.
| Year | Innovation |
| 1920s | Socket wrenches become popular. |
| 1960s | Ratcheting wrenches introduced. |
| Today | Electronic torque wrenches ensure accuracy. |
Innovative materials increase strength and reduce weight. Digital technology integrates into wrench design, revolutionizing the way we apply torque.
Standard Wrench Types
Got a nut or bolt that needs tightening or loosening? A good wrench can save the day. But not all wrenches work the same way. There are many kinds, each with a special skill. Let’s get to know the most popular trio: open-ended, box-ended, and combination wrenches.
