Self-clinching standoffs mount permanently in thin panels to stack PCBs, space sub-panels and carry threads where both sides must stay serviceable. The range covers through standoffs (SO, SOA, SOS, SO4), blind standoffs (BSO), micro standoffs for compact electronics, surface-mount (SMTSO) types for reflow lines, plus grounding, clip-on, close-to-edge, concealed-head and hole-slide variants.

Start here

• SO through standoff – the general-purpose metric type: see the SO standoff specification and type comparison
• SOS – closed end keeps the internal thread clean
• BSO – blind, protects the reverse face

For selection help, the guide SO, SOS or BSO? Specifying standoffs walks through the decision with panel-thickness and hole-size rules.
