Steel drop in anchor is composed of an anchor body with crossing groove and a conical built-in expanding steel plug. Setting tool is used to hit and insert the plug to expand non-threaded end. The full expansion of anchor body is achieved by the displacement of steel plug pre-assembled expansion mechanism. Mainly made from carbon steel, stainless steel and a small part of the copper materials,having different surface shapes, half knurling, double knurlings and non knurling types. 

   Drop in anchors is a kind of heavy duty mechanical expansion anchor bolt with internal thread,also called metal expansion nut,used to anchor and fix the fixture objects in concrete,masonry or solid brick wall substrate. Drop in expansion anchor body is manufactured by multi station molding cold forging forming machine to ensure the tightness and precision of the product and greatly improve production speed.

   Providing American system inch, British system inch and Metric system mm sizes to meet with different markets and application sites.    

[Product Features]:

● Specially designed conical built-in steel plug achieve expansion function.

● The unthreaded end is cut crossing groove to ensure to be completely expanded.

● Pre-insert a thin plastic sheet to lock steel plug and prevent it from falling down.

● Fasten various sizes of bolts, studs or threaded rods to achieve flexible fixture thickness.

● Anchor threaded end is flush with the substrate surface after removal of  the fixtures.

● Remove the fixture leave anchor body undisturbed.

● Suitable for medium-heavy duty loading installation purpose.

● Use special setting tool to install drop in anchors.
