Ancoră filetată Fischer 48284

The fischer Hammerset anchor EA II (Fischer 48284) is an internal-threaded anchor made of zinc-plated steel for secure fastening in concrete and similar base materials. It is set flush with the base surface by hammering and expands inside the drill hole when the internal rod is driven in using a setting tool. The anchor accepts standard metric screws or threaded rods and is suitable for indoor applications such as sprinkler systems, gratings and consoles.

Advantages

The embossed rim prevents the sleeve from slipping during installation, ensuring a stable hammerset fit. The metric internal thread allows use of standard screws or threaded rods for flexible application. Machine setting with the EMS tool enables fast, effortless installation for series work, while expansion embossing with the EHS Plus tool provides a simple visual control of correct anchoring. A fixing point at hef 25 mm and a black fixing point design prevent the anchor from falling out of the drill hole before expansion, which is useful for overhead and positional installation.

Suitable for

• Fixing sprinkler systems in indoor concrete
• Mounting gratings and walkways
• Attaching consoles and supports
• Indoor general-purpose fastenings with metric screws or threaded rods

How to use

Drill a hole of the specified diameter and depth for the anchor, clean the hole of dust, insert the EA II anchor flush with the base, and position the internal rod. Using the EHS Plus setting tool or the EMS machine setting tool, drive in the internal rod to expand the sleeve against the drill hole wall. For correct expansion, avoid applying torque to the screw or threaded rod during setting. After expansion, fit the appropriate standard metric screw or threaded rod to achieve the required load-bearing connection.

Recommendations

Use the EMS tool for series installations to increase speed and consistency; use the EHS Plus tool when visual control of embossing is desired. Verify substrate suitability and required embedment depth (hef 25 mm) for the planned load and follow applicable approvals and installation instructions for indoor sprinkler and support systems.
