* M6 x 50mm

* The 1/4 inch eyelet hole makes threading easy, and it sets with a claw hammer.

* The anchor has a tri-segmented clip which independently adjusts to hole irregularities.

* Dual embossments on each segment of the clip enables it to undercut into concrete, which increases follow-up expansion.

* The wedge-style expansion makes its use applicable to normal weight concrete or concrete over metal deck, and one ideal use is for installing an acoustic ceiling grid.
