Sleeved Anchor Bolts

[Nitell]

Hi
I about to fit a new gate into concrete pillars.
There are 4 X 11mm holes in the plates for the bolts, but I cannot see any of that size as illustrated in the following >

'Sleeve anchor bolts are available in various metric sizes, including one that fits a 11mm drilling diameter. For a 11mm drilling diameter, you would typically use a sleeve anchor with a metric size of M14, which has a screw diameter of 14mm and a casing diameter of 18mm'.

Does anyone have any knowledge, please?.

Thank you.

There are two sizes, the drilled hole and the bolt size. You could use M10 or M12, typically with a bolt size of 12 or 14mm. Screw fix do a wide range

That should read hole size of 12 or 14mm

Thank you.
The manufacturer says the holes in the bracket are 12mm as seen in the photo.
