M20 x 150mm Structural Bolts GAL Trade Box of 20

Heavy duty high tensile 8.8 grade structural bolt assemblies comprising:

• High strength high tensile bolt
• Structural high tensile nut (deeper than standard)
• 1 through hardened washer (recognised by the nibs) per bolt in each box or pack,
• Manufactured to Australian standard AS1252.
• Structural bolts come fully assembled with the nut and washer attached
• Hot dipped galvanised finish for maximum corrosion protection

Suitable for structural high strength bolting of steel and timber components in construction and engineering.

• For bolt lengths up to 125mm - 2 x diameter + 6mm
• For bolt lengths 125mm to 200mm - 2 x diameter + 12mm
• For bolt lengths over 200mm - 2 x diameter + 25mm

So for example an M12 x 130mm bolt will have a thread length of

24 + 12 = 36mm

All bolt lengths are measured from under the head.
