Mooring pins

[Grace and Favour]

they are good but these are even better

 

I have 4 of each and the US ones are more secure but more difficult to extract

the 'standall' type mentioned by speedwheel are also used as marquee anchors

 

the 'handle' on the us army pins is welded all round on both sides and the point is machined and quite sharp

That's an excellent price too, Magnetman.

 

If I didn't already have 4 of Speedwheel's type of ground anchors*, I'd buy from your link

(*I paid £40 for 4 x 42" ground anchors two years ago)
