One of the most popular purlin bolts for small and medium size sheds are the 12 x 30 Flanged Purlin Bolt and for bigger sheds the 16 x 30 Flanged Purlin Bolt. The 16 x 40 finds it place amongst the bigger knee, apex and hold down connections.

How tight should I tighten my sheds bolts? Numerous methods are used to tension high tensile bolts however as a rule of thumb “snug” tight plus one half turn of the nut is fine for the connection bolts. In engineers speak shanks tensions are: For M12 bolts, shank tension 50kN. For M16 bolts, shank tension 90kN.

Many professional erectors will also place a couple of construction or framing teks (14-10×20 tek) at each connection just to hold things in place whilst the are tightening their nuts and as a little insurance against a connection slipping around.
