These standoffs, which use the proven self-clinching design, install with a squeeze in properly sized round holes - and become permanently mounted in the thin sheet.

Types TSO, TSOS, and TSOA self-clinching threaded standoffs provide permanent threads in sheets as thin as .025”.

If you require a standoff which we do not offer in this bulletin, please contact us. We will be happy to work with you to satisfy your special need.
