HUS Anchor Setting

HUS Anchor Setting

For installation of HUS anchor, why the drill depth required is 10mm more than the nominal anchorage depth? What is the purpose of the 10mm allowance?

Raymond,

The reason for a slightly deeper drilled hole depth is per the ICC-ES Acceptance Criteria (ICC-ES AC193), as well as the ACI Acceptance Criteria (ACI 355.2). This deeper depth is to help to provide a void space for any remaining dust to collect when the anchor is being installed, after it is cleaned per the Instructions for Use.

Let us know of any additional questions.

Regards,

Bryan
