Questions we get asked about this item
What does the carbon steel grade change?
Carbon content sets how hard the screw can be made. C1006 and C1008 are the mild grades for low-load fixings; 10B21 is boron treated and is the one used where the screw has to be case hardened.
Can you case harden to a specification?
Case and core hardness are set against the screw type and its duty. Send the specification you work to and we will confirm against it.
