can anyone tell me where i can get a good anchor fixing to concrete into my garage floor thanks

Screwfix do a large screw type expanding plug that has a large protruding ring end (fnar fnar.. ...) that will take a chain.

Other options I have seen need to be cemented or bonded into the concrete.

With a chain in place it can't be screwed out.

Hi,

I thought all the purpose built anchors were too expensive.......so made my own.

Stainless steel eye-bolt welded to stainless steel plate then use rawl bolts attached to concrete floor. Rawl bolt heads then welded to the plate so they can't be shifted.

Pic before fitted to floor:-

seems ok that home made, anchor, should make a mass produce of them maybe, and sell them . b+q may also have them.
