- 1 For maximum performance, we recommend that you use the maximum shank length for your sheet thickness.
- 2 To minimize sheet distortion and maximize product performance, use a centerline-to-edge value greater or equal to the value specified.
- 3 HRB - Hardness Rockwell “B” Scale. HB - Hardness Brinell.
