In recent years Japan has expanded use of high-tension steel with more stringent requirements on welding. Given that testers are generally used in development and QC units and are highly-priced, factory owners hope for a way to briefly measure the bonding intensity of weld nuts. Ohashi Engineering's "ABK2700" tester can briefly measure the weld intensity of nuts and the company will target sales at automotive component plants.

The tester is 53cm x 60cm x 88.5cm in size and weighs 78 kilograms. In the measurement process, the steel is fixed and a bolt is fastened into a weld nut on the steel. Hydraulic pressure is applied from underneath to push in the bolt, and through the load cell on top, the tester measures the nut's strength up to the point where the nut detaches from the steel. The maximum load capacity is 40kN.
