PennEngineering® Thru-Hole Threaded Standoffs for Installation into Stainless Steel - Type SO4 - Metric SO4-M5-4

SO4™ standoffs are internally threaded fasteners designed for installation into stainless steel sheets as thin as 1.02mm (0.040in), providing spaced mounting for stacking or alignment. They install permanently via self-clinching in properly sized holes, leaving a flush reverse side. The SO4 series features a threaded barrel end that minimizes the required screw length. All variants in this series are made from precipitation-hardened stainless steel with corrosion resistance similar to 300 series stainless steel and are suitable for applications requiring high corrosion resistance, such as medical, food processing, or outdoor equipment. The SO4-M5-4 variant is part of this series, which accommodates M5 threads and complies with the same installation and material requirements as other SO4 standoffs.
