Product

The AnkaScrew Anchor is a medium duty, rotation

setting thread forming anchor.

Benefits, Advantages and Features

Fast and easy to nstall: imply screws into hole.

Fast and easy to remove: Screws out leaving an empty hole with no protruding metal parts

to grind off.

Close to edge and for close anchor spacing: Does not expand and burst concrete.

Installation

26.1 ENERAL INFORMATIOPERFORMANCE RELATED MATERIAL INSTALLATION RELATED

MGAL

1. Drill hole to correct diameter and depth. Clean thoroughly

with brush. Remove debris by way of vacuum or hand pump,

ompressed air etc.

2. sing a socket wrench, screw the Anka crew™ nto t e o e usng

slight pressure until the self tapping action starts.

3. ighten the Anka crew™ until flush with fixture. If resistance

is experienced when tightening, unscrew anchor one turn andre-tighten. Ensure not to over tighten.
