Hammer Fixing - M8 x 120mm - Grey

You will need an 8mm drill bit to create the pilot hole.

The minimum hole depth required is 45mm.

These hammer fixings are designed for solid substrates like concrete and solid brick. They may not provide adequate holding power in hollow or aerated materials.

The fixing can typically be removed by unscrewing the Pozidrive screw head. If it's very tight, ensure you are using the correct size bit and applying steady force.

Through fixing means the fixing passes through the item being attached and into the substrate, eliminating the need for measurements and repositioning on the substrate side. You drill one hole through both the item and the substrate.

The plug is made of grey nylon.

The screw nail has a zinc yellow passivation finish.

Ensure the pilot hole is drilled to the minimum required depth (45mm) and is clean. Check that the correct 8mm drill bit was used. Verify the substrate is solid and not hollow.

The pilot hole may be too large or the substrate might be too soft or hollow. Re-drilling with a slightly smaller bit (if substrate permits) or using a different type of fixing may be necessary. Ensure the substrate is solid.

Use a moderate force with the hammer. If the head is significantly damaged, the screw may be difficult to remove. Attempt removal with a Pozidrive screwdriver; if unsuccessful, the fixing may need to be cut flush.
