Easyfix Hex Flange Carbon Steel Concrete Screwbolt - (Dia)10mm (L)80mm

These screwbolts are designed for use in concrete, brick, stone, and masonry.

You will need a hammer drill and the appropriate drill bit size for pre-drilling, and a wrench or impact driver for tightening.

Refer to the product specifications for the correct drill bit size. Ensure the hole is clean from debris.

It is generally not recommended to reuse concrete screwbolts, as their performance may be compromised.

Do not overtighten. Tighten the screwbolt until the flange makes contact with the surface.

Avoid exposing the screwbolts to excessive moisture or corrosive substances. Consider using a protective coating if necessary, especially in outdoor applications.

If the screwbolt is too long, the excess length will not affect performance as long as it is seated properly and tightened correctly. You can also use a washer to adjust the length.

Check the hole diameter; it may be too large. Ensure the screwbolt is correctly seated and that the threads are not damaged. If the hole is too large, consider using a larger diameter screwbolt or filling the hole with an appropriate filler.

The hole may be too large or the material may be crumbling. Try a longer screwbolt or consider using a different type of fastener better suited for the material.

The hole may not be deep enough, or the material may be too hard. Ensure the hole depth meets the screwbolt's requirements. Use a higher-quality drill bit and drill slowly to avoid damaging the screwbolt.
