These bolts are not suitable for works requiring Building Control or Local Authority sign-off such as safety rails, balustrades, load-bearing joists/ wall plates etc.
Ensure the hole depth is sufficient and that the correct drill bit size was used. Check for obstructions within the hole.
The hole may be too large. Try using a slightly larger bolt or filling the hole with an appropriate filler before re-drilling.
Ensure the bolt is fully expanded. Check that the surface material is not crumbling or damaged.
