FISCHER screw anchor 522835 — pack of 2, FPX M10 for masonry and aerated concrete

The FISCHER screw anchor 522835 — FPX M10 is a zinc-plated steel anchor designed for anchoring fixtures in masonry and aerated concrete. Supplied as a pack of 2, this FPX-I type anchor is installed by pre-drilling and then driving the anchor in with a hammer; hole cleaning is not required. Setting is completed by turning a hex driver with a cordless screwdriver or ratchet so that the cone pulls into the expansion sleeve and four wings form an undercut in the drill hole. After expansion the hex socket releases automatically. The anchor is suitable for fixing suspended ceilings, railings and kitchen cabinets to aerated concrete.

Advantages

The FPX M10 offers approved metal anchoring for aerated concrete with high load capacity due to expanding wings that create an undercut, reducing the number of required fixing points. Installation is straightforward and energy-efficient, requiring no separate setting tool and preventing anchor rotation during setting. An automatic setting control helps ensure consistent performance and secure fixing.

Suitable for

• Suspended ceilings in aerated concrete
• Handrails and railings
• Kitchen cabinets and built-in furniture
• General mechanical fixings in masonry and aerated concrete

When it may not be suitable

The FPX M10 is specifically designed for porous substrates such as aerated concrete and for many types of solid masonry; it may not be optimal for substrates that require chemical anchors or where the manufacturer specifies different fixing systems (for example, hollow blocks with irregular cavities). For applications with unusual or unknown base materials, or where very high tensile loads are required, evaluate alternative anchors or consult technical guidance.

Key specifications

• Material: Zinc-plated steel
• Anchor type: Expansion screw anchor with undercut-forming wings
• Thread/size: M10 (FPX M10)
• Pack quantity: 2 pieces
• Suitable base materials: Aerated concrete (porous concrete) and common masonry
• Installation method: Pre-drill, hammer-in, set with hex driver (cordless screwdriver or ratchet)

How to use

Pre-drill the hole to the recommended diameter and depth for an M10 FPX anchor. Do not require cleaning the drill hole. Insert the anchor into the drilled hole and drive it in with a hammer until flush. Use a hex driver with a cordless screwdriver or a ratchet to turn the hex socket; the cone will be pulled into the expansion sleeve, the four wings will form an undercut in the substrate and the hex socket will release automatically when set. After setting, attach the fixture using the appropriate screw length for the thickness of the item being fixed.

What to consider before purchase

• Verify that the base material is aerated concrete or suitable masonry for FPX anchors
• Confirm required load capacity and number of fixing points for the application
• Ensure correct drill bit diameter and drill depth for M10 anchors
• Check that you have a hex driver compatible with a cordless screwdriver or ratchet for setting

Usage recommendations

Use the FPX M10 anchors in accordance with applicable load tables and installation guidelines for aerated concrete. For safety-critical or load-bearing applications, follow manufacturer specifications and, if needed, consult technical documentation or a structural engineer.
