I purchased a large second hand Crittall Green house last year and of course upon dismantling to transfer to my home, many of the aluminium bolts and nuts sheared off. I have tried high and low to obtain some replacement bolts and nuts trying other greenhouse and fixing suppliers.The bolts slots into the frame for fixing and securing, they are aluminium slotted pan head 1/2" long by 1/4" dia. The slotted pan head has to be approx 1/8" wide to slot into support channel frame, etc. Many places stock spare greenhouse bolts, but they are the type with square heads, mainly for Halls Type greenhouses. Could anyone tell me or point me in the right direct for a supplier, or perhaps an ex supplier to Crittall in the past? - many thanks in anticipation.

Have tried going to your local hardware store and matching the pieces? I'd
skip the big box store and try the old fashioned kind first for the
(hopefully) more knowledgeable help. Bring a bolt and a nut and explain the
problem.

Go to a hardware store with one of the bolts, and compare them to Torx head
hardware. You'll probably find a solution. Don't forget to buy a Torx driver
before leaving the store.

I'm currently rebuilding a Crittall greenhouse and have the same problem but being a retired Engineer I quickly found a solution.
I am using M6 x 20 (6mm dia x 20mm long) Galv Roofing bolts which have a large diameter but fairly flat dome head with cross slots. All you need to do is file two flats on the edge of the head in line with one of the slots so that the bolt slides into the slot in the framework. They are not expensive and readily available.

I have just moved my Crittall greenhouse and damaged or lost some of the special Crittall bolts. You will find quite a lot of these bolts can be replaced with ordinary Halls type or even galvanised bolts and nuts from an ironmongers as the head does not run in the channell. That should leave plenty of the Crittall ones to fit the channels which should do all you need.

Beware using steel or brass nuts and bolts on aluminium, these metals can set up localised electrical "galvanic" circuits that will quickly eat away at your ali and also ali does not like rust from steel when the galvanising breaks down. Much better to use stainless steel fixings that can be filed down in the same way.

Found a company that does the bolts and also the stainless steel clips for holding the glass in to the glaising bars.

At £3.65 for 25 bolts its probably cheaper than making them with a file :-)

The glass clips are on another page.

There are plenty of these bolts on ebay as well.
