re securing screw and wall plugs

If you want the screws to be tight and hold the clips properly, you'd have to put pressure on each one until the resin sets.

Why not put the plugs back, held in with resin and put the screws back once the resin has set?

When about 50m of cable fixed with these cleats held by screws and plugs

got taken walkies by a forklift it was re fixed by filling each hole (after blowing it clean) with hot melt adhesive and pushing the plug and screw back in. Held for several years.

I have successfully stuck wallplugs back into slightly dodgy holes preceded by a squirt of neat PVA, allowing it to dry before replacing the screw. Ordinary wood adhesive would probably work too (usually comes in convenient squirty tubes). The plug needs to be a reasonable push fit, not completely loose. Decorator's filler takes too long to set in that geometry.

Slightly bigger plugs? Maybe Fischer plugs.

Not stocked currently

That might be worth a bash.

They're a Fischer product, available elsewhere, e.g.

Thanks these ones are a bit smaller but they have the same ones as Peter's link, price delivered is comparable with Screwfix collected so I'll try some.
