Tam shield anchor loose bolt is a mechanical expansion anchors and has excellent design ideas. A whole steel sheet is rolled into cylinder anchor body and divided into 4 sections shield shape by punching machine to insert a conical nut for expanding. The surface of tam shield anchor is designed with a pair of fins and some scales shape possess anti-rotation and increase friction in the pre-drilled hole in substrate during installing. Red plastic plug inserted into cone nut protect internal threads in cone nut from dust and impurity to ensure the threads to rotate freely.

    Shield anchor tam is assembled with a hex bolt 4.8 - 8.8 grade and a Din 125/9021 flat washer and is widely used in various base materials to anchor and fix the objects.The internal thread in cone nut is made by metric or inch thread standard for ideal fixing and intalling and suitable for various application purposes. 304 or 316 stainless steel tam anchor is used in special installing place for special application purpose. During installing, to fasten the bolt or other fasteners assembled, a cone nut is pulled into and expand entirely concrete tam sleeve anchor body to form 4 sections of buttom separated-top connected shield shape and generate four directions balanced loading expansion force against the hole wall and allow to used in smaller edge and axial space.
