Cropped Head Greenhouse Bolts and Rings (15-pack, Stainless Steel) Creates Hanging Anchor Points in Glazing Bar Channels - Complete with 10 Reusable Plant Ties

Good and sturdy.

Screwed easily into the rivets on my greenhouse roof between the panels of glass and stayed securely fastened

The bolts were well produced with no burrs and well cut threads. The nut ran freely and fitted the 10mm spanner as expected. The shape of the cropped head needs some more work however; I could not easily fit these into the slots in my new Robinson greenhouse. It required considerable leverage to get the shaped head in the slot and once there, the bolt would not fully rotate to the 90° position and lock in place. This made it necessary to juggle with the bolt and a spanner to lock the bolt in a secure way.It can't be that difficult to get this sort of thing right but somehow the manager of this business has failed to ensure customer satisfaction as his product is not optimally designed for one of the UK's most prominent makers of greenhouses.

Brilliant, finally some mounting points that dont slowly slide down the greenhouse.

Seem a little pricey but being stainless steel they will last. I bought quite an expensive greenhouse and these were a little fiddly to get in the glazing bar slots but now they are in there I don’t think they are going anywhere. I considered buying the cheaper plastic option but glad I paid the extra for these.

Only just bought these ring bolts so cannot report on the long term issues. Previously bought a similar ring bolt. Excellent - could tie strings from roof bars and let the tomato plants grow up them. Problem with those bolts was they were not stainless steel. Only part was aluminium therefore the humidity corroded them.In contrast - Swoote Cropped Head bolts are stainless steel. Slightly smaller rings than others but still big enough to string through. Really impressed so far and bought more for my daughter to use in her greenhouse.Apart from letting plants grow up the string lines I will use them for fixing points when the net shading goes up when we get the summer back.Will still put wax oil or grease on them which makes it easy to undo and move them where needed.Yes they are ideal for any metal greenhouse.

Have installed a new greenhouse I need to secure my tomato plants. The anchors do the job, really pleased. Easy to use.

As previously mentioned by others, tbey wont fit Rhino greenhouse channels. However, due to the quality, I ground a bit off the sides to fit and so pleased with them. Plant ties are nice addition but not needed them myself.
