SO4-M3-4NC

Thru-Hole Threaded Standoffs for Installation into Stainless Steel – Type SO4 – Nickel Plated

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 SO4 standoffs are for installation into stainless steel sheets as thin as 1.02mm.

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.
