Super strong for concrete installations - Recommend using min 4 screws per anchor. 1 Handy Pak per 6 anchors. These patented fasteners are "UberGrade" as the manufacturer likes to say.

This fastener rates 2523 lbs/in of Tension Pullout and 3200 lbs/in of Shear strength in 2000 psi concrete.

NOTE: If your concrete is very old or you are in the Eastern States where many concretes contain higher granite composition you will require a high end drill bit. The drill bit provided is medium quality and not designed for extreme concrete density.

Use a minimum of four or a maximum of eight 9/64” x 3.5” screws to secure 6x6 or 4x4 anchor to concrete surfaces.

Requires T40 star drive bit. Handy pack includes a concrete drill bit.
