A torque wrench is a tool used to apply rotational force to a fastener, such as a nut or a bolt. It is usually in the form of a socket wrench with special features, such as a calibrated scale or pointer. Torque wrenches are available in both analog and digital forms.
The most common type of torque wrench is the beam-type torque wrench. This type of torque wrench consists of two beams: the drive beam and the reaction beam. The drive beam is attached to the tool handle and the reaction beam is fixed to the object that needs to be tightened.
What Is a Split Beam Wrench: Definition
A beam wrench is a type of torque wrench. A split beam torque wrench is a form of beam wrench. Regardless, split beams have two beams. One acts as a handle that bends predictably when rotated. The other portion gives the reading out .
They are easy to use, long-lasting, and cost-effective. The greatest split beam torque wrenches are within plus or minus 2%.
A decent split beam torque wrench would set you back no more than 200 dollars, but some might cost as much as 800 USD.
They are also popular because they don’t require batteries. This is important if you’re working in a remote area and/or an environment where sparks could ignite fumes (like oil rigs or gas refineries).
Advantages of Split Beam Wrenches:
- It can be used for a variety of tasks: split-torque wrenches have accuracy as high as 2%;
- The device is a gauge that measures torque from 0 to maximum;
- Able to measure torque in both directions and convert it into foot-pound or inch-pound units;
- It’s simple and straightforward to utilize;
- This device is affordable;
- It doesn’t require batteries or electronics that can fail;
You don’t need frequent calibration, so you save time and money on maintenance costs. The only thing you have to do is ensure your torque wrench stays clean by occasionally wiping it down with oil or lubricant if necessary – this will prevent rusting over time and make sure all parts are in good condition before using again after long periods of storage.
Disadvantages of Split Beam Wrenches:
- To ensure that the tool is always correct, you must do regular upkeeps;
- To ensure precision, you should keep an eye on the weight while using the instrument;
- Can be a bit heavy, so it might cause fatigue over time;
- The range of torque available is measured in increments. Let’s assume it has a five-step range. So selecting 5s or 0s on the knob is simple;
- It’s a bit of a pain to figure out what the torque numbers ending in 5 or 0 should be set at. This isn’t to imply that the mechanism is broken;
A split beam torque wrench is an easy-to-use and accurate tool that is perfect for automotive repair shops or anyone who needs to tighten bolts or screws precisely. It has a number of advantages over other types of torque wrenches, such as its long lifespan and affordability.
However, it is important to do regular upkeeps to ensure accuracy. Additionally, you should be aware of the weight while using the instrument to avoid fatigue.
How to Properly Use A Split Beam Torque Wrench?
There are only two simple procedures to follow:
- Make sure that the scale reads 0. Set the desired torque value into the wrench scale. Always follow the manufacturer’s instructions when applying torque; doing so may damage the bolt or fastener;
- To tighten or loosen the socket, attach it to the bolt and turn it. To tighten, turn clockwise, and to loosen, turn counter-clockwise. When you’ve reached the required amount of torque, stop;
The wrench will emit a click sound, letting you know that the torque has been applied.
1. Are split beam torque wrenches better?
It is a great tool for an automotive technician who has to do various repairs on cars, trucks, and other vehicles that use standard tools and equipment. Here are some of the types of jobs that these tools can be used for: checking oil levels, replacing spark plugs, tightening bolts with nuts or sockets.
A split beam torque wrench is a tool that allows you to adjust the tension of bolts, nuts, or sockets.
They are able to do this by using two different ways:
- through friction and/or pressure on the surface area where there is tension;
- through an external mechanism like spring-loaded jaws that push against each other when they meet any force;
A split beam torque wrench works best for tightening fasteners because it uses less energy than conventional wrenches so more work can be done in less time while doing fewer repairs due to wear and tear over time. In fact, many people prefer these tools because they allow them not only to save money but also to increase productivity without sacrificing quality.
2. How do you use a dual-beam torque wrench?
In order to use a dual-beam torque wrench, you must:
- Identify the size of the bolt or nut that you will be working with;
- Set the desired tension on the wrench by rotating the handle until it reaches the required level of tightness. This is usually done in Newton-meters (Nm) or foot-pounds (ft-lbs);
- Apply pressure to the object that needs to be tightened and hold it there while turning the wrench in a clockwise motion. If everything was done correctly, then when you release pressure from the bolt or nut, it will have been properly fastened at the correct tension;
3. Do split beam torque wrenches need calibration?
After you’re done, don’t forget to reset the split beam to zero. The calibration is dependent on how often you use it. If you use it frequently, you should have it calibrated more often; if you only use it once or twice a year, there’s no need to calibrate it. It also doesn’t hurt to get it calibrated sooner if any damage happens or if you drop it violently .
4. How do you calibrate a beam torque wrench?
The calibration of a beam torque wrench is not difficult, but it should be done with caution:
- Make sure the tool is unloaded and unplugged from any power sources:
- Find a stable surface on which to place the wrench; this could be a workbench or table;
- Using either a hex key or Allen wrench (depending on your model), turn the adjustment screw until the beam is in line with zero on the scale;
- Tighten the screw by turning it clockwise until it’s snug; you don’t want it too tight or else you’ll have to loosen it again;
- Check that the beam is still aligned with zero before re-loading and using the tool;
5. Are beam torque wrenches more accurate?
Beam torque wrenches are accurate to within 1-3%, with the middle third of the range being closer to 1%. Only aligning the zero mark is required when calibrating a beam torque wrench; this is achieved by moving the beam so that it lines up .
The wrench works by the beam being in line with zero on the scale. When it is not in line, then it means that there is some sort of force causing the reading to change. This can be due to either an incorrect calibration or from wear and tear on the tool itself. By keeping the beam in alignment, you can ensure that your torque readings are as accurate as possible.
One downside to using a beam torque wrench is that they are not always as durable as other types of wrenches. This is especially true for those made from cheaper materials. However, if you take care of your wrench and calibrate it often, then it should last for many years without any problems.
6. Are old-school torque wrenches accurate?
Old-school torque wrenches are accurate, but they’re not nearly as precise as modern ones. In fact, some of them can be off by up to 50% when measuring a fastener’s tension level.
7. Why does my torque wrench not click?
It’s possible that the fastener was overtightened, to begin with, clicking away without your attention. If it doesn’t click after a few swings, you’ll need a new torque wrench .
