Nut and Anchor Scrape Test, the most important connection parts of steel structures are anchors, bolts and nuts. Tensile tests are performed on anchors and bolts and proof load tests are performed on nuts. With the tensile test for bolts, it is tested whether the bolt body provides the desired strength. In the load test for nuts, the nut is loaded up to the test load, then it is released and checked whether it works by turning it by hand.
