Part # SO4-M3-12, Thru-Hole Threaded Standoffs for Installation into Stainless Steel - Type SO4 - Metric
These standoffs, which use the proven self-clinching design, install with a squeeze in properly sized round holes - and become permanently mounted in the thin sheet.
Types SO4 standoffs are for installation into stainless steel sheets as thin as 1.02mm.
If you require a standoff which we do not offer in this bulletin, please contact us. We will be happy to work with you to satisfy your special need.

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.
