Concrete expansion anchors Celo 98FXSZ FX 8x40 with screw 5x60 mm — pack 50

Celo 98FXSZ FX 8x40 concrete expansion anchors supplied with 5x60 mm screws (pack of 50) are mechanical anchor fasteners designed for use in concrete and solid masonry. Each anchor features an 8x40 mm nylon or plastic anchor body that expands when the included 5x60 mm screw is driven in, creating a secure hold for a range of light to medium load applications. This pack contains 50 complete anchor-screw sets, ready for installation on fixtures, rails, brackets and other elements that require reliable mechanical fixing in solid substrates.

Advantages

The Celo 98FXSZ anchors are supplied as matched sets with screws sized to ensure proper expansion and retention. Their design provides consistent mechanical expansion in concrete and solid masonry, delivering predictable load-bearing performance for common installation tasks. Supplied in a bulk pack of 50, they offer convenience for projects and maintenance tasks where multiple fastenings are needed, helping to reduce time spent matching screws and anchors on site.

Suitable for

• Fixing rails, handrails and brackets to concrete or solid brick
• Mounting light structural elements and fixtures such as cable trays or signage
• General-purpose mechanical anchoring in foundations, walls and floors made of solid masonry

When it may not be suitable

These expansion anchors are intended for use in concrete and solid masonry only. They are not designed for hollow blocks, aerated concrete without specific validation, or other hollow substrates where expansion cannot develop against solid material. For heavy structural loads or critical safety applications, use anchors and fixings specifically rated and approved for those load conditions and follow engineering guidance.

Key specifications

• Anchor body diameter: 8 mm
• Anchor body length: 40 mm
• Matching screw size: 5 x 60 mm
• Material: mechanical expansion anchor body with matching metal screw (manufacturer typical materials for this anchor type)
• Pack quantity: 50 complete anchor-and-screw sets
• Intended substrate: concrete and solid masonry

How to use

Drill a hole in the concrete or solid masonry to the correct diameter and depth for an 8x40 mm anchor body, ensuring the hole is clean and free of dust. Insert the anchor body flush with the surface, place the fixture over the anchor and drive the supplied 5x60 mm screw into the anchor body until it expands and seats firmly. Tighten the screw to achieve the required clamping without over-torquing. Follow standard installation practice: check hole alignment and depth, verify substrate condition, and use appropriate drill bits and torque control.

What to consider before purchase

• Confirm the substrate is solid concrete or solid masonry suitable for mechanical expansion anchors
• Verify the 8 mm anchor diameter and 40 mm embedment length meet the load and edge-distance requirements of your application
• Ensure the included 5x60 mm screw length is appropriate for the thickness of the fixture being fastened
• For hollow or lightweight blockwork, or for heavy-duty structural needs, select a different anchor type or consult technical guidance

Usage recommendations

Use a correctly sized hammer drill and appropriate masonry bit for clean holes, blow or brush out debris before insertion, and apply controlled torque when driving the screw to ensure consistent expansion. For demanding or safety-critical fixings, consider engineering checks or a specialist anchor with certified load ratings.
