Solved a problem with UK weather
Screwed them through the plastic sheets on our timber greenhouse and so far it’s stopped the plastic ripping in the wind/storms. Seems to have spread the load nicely on the old fixing points. Simple and cheap fix to a recurring problem.

Easy to use, good product.
Used these to hold up polystyrene sheets as lining for my new wooden shed. Worked really well, just had to make sure that the screws weren't too long.

Good quality
Used for screwing cement-faced XPS panels to studs. Good quality item. Works well. Particularly good for overlap between two boards as diameter is quite large.

Very handy and easy to use
These are great but the plastic isn't as strong as some I've bought hence the 4* but they do the job. Would be useful if they were slightly thinner so the plaster goes on better
