purlin bolts

Purpose made bolts specifically for the fixing of steel roof purlins.

Made in quantities to feed a mass market they are consequently very cheap. The bolts are always coated with galvanic type protection and they can also be had with a hot dipped galvanised coating. They come in the two main sizes. 12mm (as in the photo) and in 16mm.

Some of them come with a slightly serrated inner face to the washer surfaces.
