Mankate Self Undercut anchors

It is a type of metal mechanical anchor consisting of a cutting edge lock key, sleeve, screw, spring washer, flat washer, and nut. The unique design of the single-cutting edge lock key allows it to easily penetrate the hole wall, creating a locking effect to ensure that the anchor bolt complies with the specified slip requirements when subjected to tension. The product has passed the national fatigue resistance test of over 2 million cycles and a 3100-hour salt spray test without rusting. It has also obtained national seismic resistance and anti-loosening certification, as well as performance testing certification from the European Union's "ETA" organization.
