The “L” dimension is the height of the installed stud at max grip. The height of the stud will increase if it is installed into thinner material. To calculate “actual L” use this formula: max grip - actual grip + L = “actual L”
2
To minimize sheet distortion and maximize product performance, use a centerline-to-edge value greater or equal to the value specified.

HRB - Hardness Rockwell “B” Scale. HB - Hardness Brinell.
