Choosing a purlin bolt
Choose the size and length for the purlin and the cleat, then the class and finish. Class 4.6 is a lower strength and class 8.8 is high tensile. Hot dip galvanised suits outdoor and exposed structures, and zinc plated suits dry, protected locations. Choose a kit if you want the bolt and nut supplied together, and a boxed pack for bulk jobs. Check the variants on the product page for sizes and pack quantities.
Always check the data sheet. Confirm the strength class, finish and length before you order, and check it suits your structural design.
