Concrete drop in anchor is an internal thread, heavy duty mechanical expansion anchor,pre-assembled an expanding plug inside. One non-threaded end is cut crossing groove and locked a plastic sheet to fix the steel plug to protect it from sliding from the body no other function. Drop in anchor body is mainly made of stainless steel and carbon steel, but a small part of the copper material. Special setting tools are required for drop in anchor installation. 

   Drop in expansion anchor has internal thread, accepts M6-1/4" to M20-3/4" inch and metric standard bolts or threaded rods to be flush mounted,called metal expansion nut as well, with half, double or non knurling surface types. It is suitable to be embedded applications in concrete or solid brickwork substrates for anchoring and fixing the objects or connect-fix the rebar or threaded rod. The steel expanding plug is pushed to the bottom of the anchor by using the special setting tool to expand one non-threaded end of the anchorage to realize the expansion function. 

[Product Features]:

● The non-threaded end is cut crossing groove to ensure to be completely expanded.

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

● Remove the fixture leave anchor body undisturbed.

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

● 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.

● Use special setting tool to install drop in anchors.

● Suitable for medium-heavy duty loading installation purpose.
