Need help finding a 'thing'! Don't know what they are called!

[Seb101]

Hi all,

I have a deck in the garden, I want to be able to erect a shelter over the deck for temporary periods, and fasten it to the deck.

So what I'm looking for is essentially a permanent anchor fixing that I can sink into the decking structure that will accept into it an M6 bolt that I can temporarily use to bolt things down. But when I remove the M6 bolt I want the anchor to stay permanently and securely in the deck, so it's not just a regular 'expanding bolt' or similar that I'm looking for.

I am sure these exist, but I have no idea what they are called or where to find them! Any ideas?!

Cheers.

I'm not sure it's 100% designed for it, but it seems like this would do the job in the absence of anything proper:

The 'sleeve' anchor stays in the rawl plug even when the bolt is removed.

Or these if they were a bit longer

Nevermind! Answered my own question!

'Insert nuts' or 'screw-in sleeves'

You can get them 20mm long...

edit: I see you have found them, those are "type D" which means they have a flange at the top to stop them threading in too far. 'Type E' ones don't have the flange, so can go deeper in the wood, to be more hidden if that's what you want.

I don't know the English name for it
