These standoffs, which use the proven self-clinching design,
install with a squeeze in punched or drilled round holes – and
become permanently mounted in the thin sheet.
PEM? brand thru-hole threaded standoffs (Page 5) are installed

When blind-threaded types (Page 6) are used, outer sheet
surfaces are not only flush, but closed as well. Unthreaded
standoffs (Page 7) are also available for spacing multi-panel
assemblies.
