Torque Wrenches & Fasteners
Proper Tightening
Learn TechniquesProper torque aplicação ensures fasteners são tight enough to hold but not so tight they strip ou break. Torque wrenches provide precise, repeatable tightening for safety-critical aplicações.
Comuns Torque Specifications
| Aplicação | Torque (N·m) | Torque (ft·lb) |
|---|---|---|
| Spark plugs | 15-30 | 11-22 |
| Lug nuts (car) | 100-140 | 74-103 |
| Cylinder head bolts | 40-80 | 30-60 |
| Oil drain plug | 25-40 | 18-30 |
| Bicycle pedals | 35-40 | 26-30 |
Always verify specifications for your specific aplicação.
Conclusão
Torque wrenches são essential tools for safety-critical fasteners. Always use manufacturer specifications, apply torque smoothly, e calibrate tools regularly. For wheel lug nuts e engine components, proper torque prevents dangerous failures.
