ALM Aluminium Cropped Head Nuts & Bolts (Pack 20) -GH003, Silver

Easy to use. Be careful that the tops don't break off.

I like that this fits my Palram Harmony greenhouse. I don't like that the metal is so soft. A couple of them broke while tightening.

These are exactly what I needed for the greenhouse. The delivery was not expected until Feb 14 but I received them Jan 29th.

The bolts are made of very soft useless metal. The first time I went to tighten one, the bolt snapped off the head. Not even worth the $3 price.

The bolts will fit into the channels in my greenhouse supports, but they have rounded off the wrong corners on the bolt head. Instead of locking in when I tighten the nut, the bolt head rotates and slips out. If I had three hands I might get this to work. Terrible design flaw for a simple item.

Too many other nuts and bolts do not fit Palram greenhouses. These do, so I am happy.

Good product, bit fiddly as the slot is a bit generous. Bluetack on a a flat blade screwdriver to hold in place while tightening solved the issue.

Fitted Perfect for putting extra supports on greenhouse. Went in Groves much better than other brands I have tried. Got some spare for bolting things on if needed.

Looks good enough.

There's a nut and a bolt. They tighten together and hold things in place. Marvellous!
