Hobson K0 Structural Assembly, M16 / 45

The Hobson K0 structural assembly is supplied in class 8.8 with a hot dip galvanised finish. The range has 223 items, from M12 x 30mm to M36 x 600mm: 164 sold in boxes and 59 as single assemblies. This product is a structural assembly.

Class 8.8 is high tensile, and corresponds to imperial grade 5. The Hobson guide gives a minimum tensile strength of 800 MPa for class 8.8 sizes below M16 and 830 MPa for M16 to M72, so M12 items are 800 MPa and M16 to M36 items are 830 MPa. This is the class minimum from a head-marking table and not a test result for the item. 8.8S means snug tight, 8.8TB means a bearing joint with bolting fully tensioned and 8.8TF means a friction joint with bolting fully tensioned, all means per AS4100.

Choosing the right option
