A beam torque wrench is the simplest type of these instruments. Meaning that the price is quite affordable as well. It can also be called a torque wrench of the torsion type, as it consists of two levers. The first one is used to apply torque to the tightened connection and serves as a tool’s handle. A second lever at the other end is attached to the tool’s head and it is free at the other end, serving as a beam or pointer that indicates the applied force on a scale at a particular point in time.
Pros and cons of beam torque wrenches
Like any tool, such wrenches have pros and cons that I’d like to share, according to my humble experience.
- Low price. Beam torque wrenches have the lowest price among all of them
- Allows you to work “clockwise” and “counterclockwise”
- It has a simple construction
- The highest error percentage among all models
- It is not adjustable over time, the tool wears out and loses the accuracy
- No ratchet mechanism allows avoiding rearranging the tool when tightening the fasteners
- During operation, the applied force must be controlled by the indicator (beam). For me it is not convenient, especially in hard-to-reach places
What to look for when buying a beam torque wrench?
Many U.S. manufacturers offer to use the device for the torque wrench – a multiplier. The mechanism of work is based on the operation of the gearbox – amplifier (the gear system). It’s attached to the torque wrench and increases the applied force on the bolt several times (according to the manual).
Judging from my experience, I’d like to recommend a few awesome beam torque wrenches:
- ARES 70213 with high visibility marks and 0-9 Nm;
- Neiko 03727A has an accuracy rate of 4% (more or less);
- Tooluxe 03703L provides a 17-inch long shaft with an included adapter;
When buying a torque wrench, you need to know exactly what kind of work you need it for, since the manufacturers produce the tools with different ranges. Their size can be different: small with a range of ¼ inches and huge with a torque range of ¾ inches.
