Tension bolt performance testing. We also accept commissioned testing of products from other companies.
We can conduct performance tests of fastening components using various testing equipment. In addition to vibration tests using the Junker and NAS combined screw loosening test machines, we have also introduced a torque testing machine, allowing for torque measurement during fastening. We accept testing not only for our products but also for products brought in from other companies. If you are interested, please feel free to consult with us.
