What is the difference between a direct pull test and a torque test?

A direct pull test (pullout test) applies a controlled tensile load directly to the installed anchor to measure its actual load-bearing capacity and bond strength with the base material. It provides a direct assessment of how the anchor behaves under real tensile forces, making it more reliable for verifying structural safety.

A torque test, on the other hand, measures the installation tightening torque applied to mechanical anchors. It is mainly used to ensure that the anchor has been installed correctly and has achieved the required friction or expansion force. However, it does not directly measure ultimate load capacity.

In the Indian construction and infrastructure sector, direct pull testing is commonly used for critical applications such as buildings, bridges, metro projects, and industrial structures, while torque testing is often used for quick installation checks and quality control of mechanical anchors.

At Uniquo, we provide both direct pull testing and torque testing services based on project requirements, ensuring accurate verification, safety compliance, and quality assurance across construction projects in India.
