Wurmi pegs are expensive and don't stand up to heavy usage.  They can't cope with hardstanding and are only good on soft ground.  I just use mine in the garden now and have gone back to rock pegs. Don't waste your money.

Strange!!!!

All the folks that I know that use them properly swear by them.

We use them on all types of ground and have never had one break.

Easy to put in and even easier to come out, with a 12v rechargeable drill, putting up the awning is a breeze now instead of a chore.

I have artificial knee joints and cannot kneel down so using conventional mallet driven pegs is no longer feasable but thanks to Wurmi, the Mallet Pegs are consigned to where they belong. A Museum.

Excellent work better and much cheaper

I would certainly promote screw-type pegs for those with back/hip/knee/shoulder problems simply for their ease of insertion.

There is a misconception though that the screw thread creates a better hold.

Unfortunately, the greatest hold of the thread would be at 90 degrees to the surface of the helix or parallel to the shank. When your guy is attached to the top of the screw-peg, the tension is at (approx) 90 degrees to the shank rendering all the holding power of the thread useless(i.e. nothing to stop it moving sideways).
Screw-pegs act exactly the same as standard pegs in normal soil when inserted although they maybe more rigid.

And sometimes screw-pegs don't unscrew because earth is not that substantial.

I use them on my awning and am very impressed with their general performance

I am absolutely sure you are. Nothing wrong with screw pegs, rock pegs, standard pegs, titanium,carbon fibre or good old fashioned wood pegs. I was only pointing out the limitations of the screw thread and why it doesn't help to hold the guy at that particular angle of approx. 45 degrees.
One thing I don't think anybody should say though, is that all non-screw pegs should be removed to a museum (as suggested earlier) as if screw pegs are the most reliable thing going. They ain't. Nor are Delta pegs.
