The number of torque wrenches you need will depend on the types of projects you will be working on and the range of torque values you need to apply.
If you are working on a variety of projects that require different torque values, it’s a good idea to have at least two torque wrenches, one that can handle lower torque values and one that can handle higher torque values.
For example, you might want to have a beam-style torque wrench for lower torque values and a click-style torque wrench for higher torque values.
If you are working on a specific project or have a specific torque range you need to apply, you may only need one torque wrench that can handle that range.
It’s also important to consider the accuracy of the torque wrench, most of the time a torque wrench have a range of accuracy of +-4% which should be enough for most tasks, but for more precise tasks, you might want to consider a torque wrench with a higher accuracy range.
In general, it’s a good idea to have at least one torque wrench on hand, and to have multiple torque wrenches if you are working on a variety of projects or need to apply a range of torque values.
How do I know which torque wrench I need?
When choosing a torque wrench, there are several factors to consider:
- Torque range: The torque range of a wrench is the range of torque values it is capable of measuring and applying. Choose a torque wrench with a range that will accommodate the torque values required for the tasks you will be performing.
- Drive size: The drive size of a torque wrench refers to the size of the socket or adapter that is used to apply torque to a fastener. Make sure to choose a torque wrench with a drive size that is compatible with the sockets or adapters you already own or will be using.
- Accuracy: The accuracy of a torque wrench is the degree to which the wrench can measure and apply the specified torque value. Most torque wrenches have an accuracy range of +/- 4%. If you need higher precision, you may want to consider a torque wrench with a higher accuracy range.
- Type: There are different types of torque wrenches, such as beam-style, click-style, micrometer-style, and electronic. Each has its own advantages and disadvantages and suit different needs and preferences.
- Measurement units: Some torque wrenches measure torque in pound-feet (lb-ft) or newton-meters (Nm), make sure the wrench you choose measures torque in the units you are most comfortable with.
- Durability: Consider the build quality of the torque wrench, specially if you plan to use it frequently, you want to make sure it is durable enough to withstand regular use.
It’s important to research the torque wrench that would best suit your needs and compare the features and specifications of different models before making a decision. It’s also recommended to consult the manufacturer’s manual or the technician responsible for the task for specific recommendations.
How much torque do I need for automotive work?
The amount of torque needed for automotive work will vary depending on the specific task and the vehicle. Here are some general guidelines:
- Spark plugs: Torque values for spark plugs typically range from 12 to 15 lb-ft (16-20 Nm) for most vehicles.
- Wheel lug nuts: Torque values for wheel lug nuts typically range from 80 to 100 lb-ft (108-136 Nm) for most vehicles.
- Oil filter: Torque values for oil filter can range from 7-10 lb-ft (9-14 Nm) for most vehicles.
- Oil drain plug: Torque values for oil drain plug can range from 18-30 lb-ft (24-41 Nm) for most vehicles.
- Timing belt tensioner: Torque values for timing belt tensioner can range from 15-50 lb-ft (20-68 Nm) for most vehicles.
- Rocker arm: Torque values for rocker arm can range from 20-50 lb-ft (27-68 Nm) for most vehicles.
It’s important to consult the vehicle’s service manual or the technician responsible for the task for specific torque values. It’s also important to use the right size socket or wrench and make sure the nut is not too tight before using any of this methods. Additionally, it’s important to use proper safety equipment such as gloves and safety glasses, as removing axle nuts or other automotive parts can require a significant amount of force.
