PennEngineering® Thru-Hole Threaded Standoffs for Installation into Stainless Steel - Type SO4 - Unified SO4-8632-10

Type SO4 standoffs are internally threaded fasteners designed for installation into stainless steel sheets as thin as 0.040" (1.02 mm), providing threaded mounting points for stacking or spacing applications. They install permanently using a squeeze method in properly sized holes, with a flush and smooth reverse side after installation. These standoffs are made from precipitation-hardened stainless steel for enhanced hardness and corrosion resistance comparable to 300 series stainless steel, suitable for use in corrosive environments. The product line accommodates a range of thread sizes, including 8-32 thread, and maintains consistent material properties across variants.
