Torsion Testers: Precision Equipment for Evaluating Material Strength and Performance
Torsion testers measure the properties of materials and components under twisting forces using torsional testing principles. It evaluates performance under torsional loading, which helps engineering teams determine maximum torque, torsional shear stress, and ultimate torsional strength. Torsion testing is essential for evaluating the quality assessment, quality control, performance, and durability evaluation across a wide range of products, such as screws, springs, wires, tubes, and medical devices. The products a company manufactures or uses determine the torsion test application range.
At Test Machines Australia, we offer torsion testing machines to suit your testing needs and applications. Our systems support a simple torsion test as well as enable you to carry out advanced analysis. This way, it is possible to arrive at accurate measurements of properties like shear modules. Our equipment is designed and manufactured in line with the highest standards of accuracy, reliability, and efficiency.
Whether you need to test the torsional strength, stiffness, modulus, shear, stress, or breaking angle of your materials or products, our torsion testing machines deliver consistent and reliable results across varied torsion test application requirements. Contact us today to learn more about torsion testers and how to procure them!
How Do Torsion Testers Work?
Torsion testers apply a controlled twisting force to test the specimen to measure its resistance to torque or angular deformation during torsional testing. This process helps determine maximum torque, torsional shear stress, and performance under torsional loading. The tester is most commonly used to test components such as screws, wires, tubes, and automotive parts that experience twisting forces during operations, which makes it a crucial torsional test application.
The component or specimen is clamped at both ends, with one end fixed and the other rotated at a controlled speed to perform a simple torsional test. As torque is applied, sensors measure the twisting angle and the resulting stress. This data measures the shear strength, torsional stiffness, and failure points of the component. Through the tester, manufacturers simulate real-life situations to check their durability, quality, and design accuracy.
Common Standards for Torsion Testing
The common standards for torsion testing used with torsion testing machines include:
- ASTM A938 / ISO 7800 (Metallic Wire): Used to check the ductility of wires by repeated twisting until they break or a specific number of twists is achieved
- ASTM F543 (Medical/Bone Screws): Used to check the torsional yield strength, maximum torque, and breaking angle of bone screws
- ASTM E143 (General Metals): Used to check the shear modulus or rigidity of structural materials
- ISO 7206 (Implants): Used for fatigue testing and endurance of artificial hip implants
- ISO 594 / ISO 80369 (Luer Fittings): Used to check the torque-based security of medical connectors

FAQs About Torsion Tester
What materials can be tested with a torsion tester?
A torsion tester can be used to test materials such as metals, alloys, plastics, rubber, wires, rods, fasteners, and composite materials. Any product or component that is subjected to torsional forces during operations can be tested with the help of a torsional testing tool.
How do I choose the right torsion tester for my lab?
To choose the right torsion tester, you need to first analyse the materials and specimens that need testing, along with the compliance standards followed in your industry. After this, you should check whether the torsion tester matches the torque capabilities, speed, and software capabilities you need for efficient testing.
What industries commonly use torsion testers?
Torsion testers are widely used across biomedical construction, aerospace, automotive, and manufacturing industries. Torsion testing equipment is used to assess the durability, strength, and safety of materials and specimens to which twisting forces are applied during operation. It is commonly used to test wires, fasteners, cables, medical implants, and springs, among other materials.
How accurate are torsion testers for torque measurement?
Torsion testers are highly accurate for torque measurement. They typically offer accuracy between ±0.5% and ±1%. However, their accuracy also depends on other aspects such as testing conditions, load cell quality, sensor resolutions, and calibrations.
