Questions we get asked about this item
Why does the nut grade matter?
A nut weaker than the bolt strips before the bolt reaches its design load, so the connection never develops the strength it was drawn for.
Can you supply to a customer drawing?
Special design to drawing sits alongside IFI, DIN, JIS and GB across the bolt range.
