Celo 910FXK concrete expansion anchors FX 10x50 with screw 7x65 mm, pack 25

Celo 910FXK concrete expansion anchors FX 10x50 with screw 7x65 mm, pack 25 are mechanical fasteners designed for secure anchoring in solid concrete. Each kit contains 25 FX-type expansion anchors sized 10x50 mm and matching 7x65 mm screws to create a reliable threaded connection. The system transfers load through radial expansion inside the drilled hole, offering a stable hold for mounted fixtures and structural elements in both indoor and outdoor environments.

Advantages

The anchors provide predictable expansion behaviour in solid concrete, ensuring consistent load-bearing performance. Inclusion of matched 7x65 mm screws in the pack simplifies installation by eliminating the need to source separate fasteners. Their corrosion-resistant finish and robust design make them suitable for a variety of common construction and installation tasks where a threaded connection is required.

Suitable for

• Fixing brackets, rails and handrails to solid concrete walls
• Mounting machinery baseplates or support frames
• Anchoring shelving, cabinets and heavy fixtures in concrete
• General-purpose concrete fastening for indoor and sheltered outdoor use

When it may not be suitable

These expansion anchors are intended for use in solid concrete. They are not suitable for use in hollow blocks, drywall, or weak, crumbly substrates where expansion cannot develop reliably. For applications requiring high corrosion resistance in aggressive outdoor or marine environments, a stainless steel anchor or alternative chemically bonded system should be considered.

Key specifications

• Anchor type: Expansion anchor (FX type)
• Anchor dimensions: 10 x 50 mm (diameter x length)
• Screw size included: 7 x 65 mm (diameter x length)
• Pack quantity: 25 complete anchors with screws
• Installation method: Mechanical expansion in drilled concrete hole

How to use

Drill a hole in solid concrete to the anchor diameter and required depth, clean the hole of dust and debris, insert the FX anchor flush with the surface, and drive in the supplied 7x65 mm screw. Tightening the screw causes the anchor sleeve to expand against the hole walls, creating the holding force. Follow recommended drilling diameter and embedment depth for the anchor size, and use appropriate torque to avoid over-tightening.

What to consider before purchase

• Verify substrate is solid concrete suitable for expansion anchors
• Confirm anchor size and embedment depth match the load and fixture requirements
• Check whether the included screw length is appropriate for fixture thickness
• Assess environmental exposure to determine if standard finish is sufficient

Usage recommendations

Use a hammer drill and correct masonry drill bit for clean holes; clear dust with a brush or blower. Observe recommended torque values and embedment depths for the 10x50 anchor to achieve specified holding capacity. For safety-critical or high-load applications consult relevant fixing tables or a structural engineer.
