Cropped Head Bolts are designed to fit into the underside of the glazing bar once the greenhouse frame has been assembled this will allow you to fit and move around accessories like shelf brackets, the cropped head is made so it is the same or smaller than the channel so you can easily fit then turn when in position.
They can also be used for an emergency repair if you need to replace a square head quickly you should always change back to a square head bolt as soon as you can, do not be tempted to use these bolts for construction I have seen several flattened greenhouses because cropped have been used to build the frame because it was easier.
They will fit most aluminium greenhouses and are supplied with M6 aluminium Nuts, the bolt thread is 11mm.
