Questions we get asked about this item
What does 8.8 mean?
The first figure is one hundredth of the nominal tensile strength in MPa; the second is ten times the ratio of yield to tensile. An 8.8 bolt is nominally 800 MPa tensile with yield at 80 per cent of that.
Can you supply bolt, nut and washer together?
Yes — nuts and washers are made on the same catalogue, so an assembly can be quoted as one line.
