Celo hollow wall anchor BT plus M8 20 pcs, model 9Y8BTPK

Celo hollow wall anchor BT plus M8 20 pcs, model 9Y8BTPK is a pack of 20 anchors designed for secure fastening in hollow or cavity substrates. Intended for use with M8 threaded connections, these anchors expand inside voided materials such as hollow blocks, plasterboard, and other cavity walls to provide a reliable mounting point for fixtures and fittings in light to medium duty applications.

Advantages

The Celo BT plus M8 anchors provide consistent expansion and load distribution within hollow substrates, enabling stable and repeatable installations. Supplied as a set of 20 pieces, the kit supports multiple fixings on a single job site and reduces the need for individual handling of loose items. The design is suitable for common hollow building materials and simplifies installation by matching standard M8 threaded fasteners.

Suitable for

• Fastening fixtures to plasterboard and drywall
• Mounting light-to-medium weight items to hollow block walls
• Securing fittings in cavity walls and partition systems
• Installation tasks requiring M8 threaded connections

When it may not be suitable

The BT plus M8 anchors are intended for hollow and cavity substrates and are not suitable for solid masonry or concrete where through-bolts, chemical anchors or expansion bolts are recommended. They are designed for light to medium loads; for heavy structural loads or dynamic forces, select anchors specified for higher load capacities and appropriate substrate testing.

Key specifications

• Anchor type: hollow wall/cavity anchor
• Thread size compatibility: M8
• Pack quantity: 20 pieces
• Intended substrates: hollow blocks, plasterboard, partition walls
• Application load class: light to medium duty installations

How to use

Drill a hole of the appropriate diameter for the anchor in the chosen hollow substrate following manufacturer recommendations. Insert the anchor into the hole until flush with the surface, then tighten the M8 threaded fastener; the anchor will expand behind the board or block to form a secure fixing. Verify correct engagement by checking that the anchor is firmly seated and the mounted item has stable support. Where available, follow any torque values or installation instructions provided by the anchor manufacturer.

What to consider before purchase

• Confirm substrate type (plasterboard, hollow block, partition wall) to ensure compatibility
• Verify required load capacity and whether light-to-medium duty anchors meet the application needs
• Check that M8 thread size matches the bolts or fittings to be used
• Ensure correct drill bit size and installation tools are available

Usage recommendations

Use these anchors for non-structural fixtures such as shelves, brackets, light fittings and sanitary accessories in hollow walls. For critical or heavy-load applications, perform a substrate assessment and select anchors or fixing methods rated for the specific load and conditions.
