Ancre à visser Fischer 48339

The Fischer 48339 screw anchor is a single-piece anchoring solution intended for secure fastening in a variety of base materials. Designed by FISCHER for simple installation and reliable load transfer, this anchor suits small mounting tasks where a compact, effective fastener is required. The product is supplied as one unit and is lightweight, making it convenient to handle on job sites and during home improvement projects.

Advantages

The screw anchor combines ease of installation with consistent expansion behaviour to provide a reliable hold in materials such as concrete, solid brick and some hollow substrates. Its compact dimensions and low weight reduce handling effort, while the engineered geometry ensures repeatable anchoring performance. The single-piece design simplifies inventory and selection for specific small-scale mounting tasks.

Suitable for

• Mounting fixtures and small fittings to concrete and solid masonry
• Light-duty installations such as hooks, cable clips and small brackets
• Repair and renovation projects where precise, compact anchors are needed

Key specifications

• Packaging quantity: 1 piece
• Package weight: approximately 20 g
• Type: single-piece screw anchor designed for mechanical expansion
• Typical base materials: concrete, solid brick, selected hollow masonry
• Intended use: light-duty to small-medium fastening applications

How to use

Drill a hole of the specified diameter and depth appropriate for the anchor and the base material. Clean the hole of dust and debris before inserting the anchor. Insert the screw anchor into the hole flush with the surface, then tighten the screw or bolt to the recommended torque to activate the expansion mechanism. Verify the anchor’s engagement and ensure the mounted object is secure. Refer to FISCHER installation guidance for exact drill sizes and recommended tightening torques for differing substrate types.

Recommendations

Use the screw anchor only in suitable base materials and with matching screw or bolt dimensions. Avoid using the anchor in highly cracked concrete or in substrates that do not provide sufficient confinement. For loads beyond light-duty use, select an appropriately rated anchoring system and follow manufacturer specifications for spacing, edge distances and load values.
