PennEngineering® Thru-Hole Threaded Standoffs for Installation into Stainless Steel - Type SO4 - Metric SO4-M5-25

SO4™ standoffs are internally threaded fasteners for installation into stainless steel sheets as thin as 0.8 mm, providing flush mounting and permanent attachment. They are designed for stacking or spacing applications and feature a threaded barrel end to minimize the screw length required. Made from precipitation-hardened stainless steel, they offer corrosion resistance similar to 300 series stainless steel. The part is installed using a squeeze method in properly sized holes and remains permanently fixed after installation. All SO4 variants share these base characteristics, regardless of thread size or length.
