Product Specifications
Evaluating a wrench's quality is not solely based on torque.
| Item | Detail |
|---|---|
| Tough fracture | noticeable plastic deformation before breaking, absorbs most energy during failure, protecting user safety. |
| Brittle fracture | little to no plastic deformation before breaking, releases all energy instantly, posing safety risks. |
Wrenches that deform before breaking provide user warnings and enhance safety.
Comprehensive quality assessment includes material, safety, after-sales service, and overall performance.
Wrench size depends on the size of screws or nuts.
