A recess under the hex clinches a panel for a strong hold that won't push, pull, or twist out. When mounted with a lever press, the hex sits flush with the surface and the open end creates a through hole. These are also known as captive standoffs.

18-8 stainless steel standoffs have good corrosion resistance and are nonmagnetic.

Zinc-plated steel standoffs have some corrosion resistance.

Miniature Press-Fit Threaded Standoffs with Open End

Designed to fit in the limited space of compact electronics, such as laptops and hand-held devices, these standoffs have a recess under the head that clinches a panel while splines on the head bite in for an extra-stong hold. The open end creates a through hole. Standoffs have excellent wear resistance and may be mildly magnetic. Use a lever press to install.
