DSO-440-250ZI
Threaded Standoffs for Close-To-Edge Applications – Types DSO, DSOS
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 DSO and DSOS standoffs are available for close-to-edge applications.
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.
Available in other lengths on special order.
