    Drop in expansion anchor is one of metal expansion anchor system with internal thread and designed the diameter refering to the external diameter of anchor body,produced by the multi station molding machine to ensure the precision of products and the stability of material properties, greatly improve the quality of products and production speed,mainly made from carbon steel or stainless steel materials.

★ The external diameter of anchor body is equal to the hole drilled diameter in the concrete site. 

★ Min.embedment depth is the length of the anchor.

★ Insert the anchor into the pre-drilled hole keeping the threaded head end towards the substrate surface, then use a proper setting tool and hit the built-in steel expanding plug until to be fully expanded.

    Ideally suited for the medium to heavy duty fixing purposes. Masonry drop in Anchors are available in Metric and Inch size type from 1/4"(M6) to 3/4"(M20), meet various construction installation need. The fixtures could be removed,not affecting drop in anchor installed.

[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.

 Threaded end of the anchor 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.

Also called metal expansion nut or steel expanding nut.

 Use special setting tool to install drop in anchors.

 Suitable for medium-heavy duty loading installation purpose.

[Materials & Surface treatment]:

 Carbon steel & ZP / ZYP

 Stainless steel 304 / 316.

[Base Materials]:   Concrete  Masonry  Brickwork  Solid wall  Stone


 Railing,special door industry,wall panel.

 Installation of interval signs, handrails, railings, shelves ,wood plate,wall hanger,bracing,shelving and gates.

 Installation of console grating and fence and heavy machinery location installing.

 Pipe installation engineering / pipe support.

 Temporary work such as steel truss for platform safety rings & brickwork structure.

 Installation of banister starter bars for structural expansion,stadium seats and rectification works.

 Steel building structural expansion and rectification works.

 Fix and connect threaded rod or rebar.

 Fix air ducts, cable tray, trunking, mechanical pumps and electrical switch gear.

[Installation Steps]:

 Drill a hole in the base material to ensure the proper diameter and depth required.

 Use a nylon brush to remove all debris and dust.

 Hammer anchor body into the drilled hole till threaded end is flush with substrate surface.

 Hit the built-in steel plug with setting tool until the shoulder meets the top of anchor body.

 Tighten the bolt or other fasteners to fix and install the objects.
