Part # SO4-4116-22, Thru-Hole Unthreaded Standoffs - Type SO4

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.

Unthreaded standoffs are also available for spacing multi-panel assemblies.

¹ 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.
³ HRB - Hardness Rockwell “B” Scale. HB - Hardness Brinell.
