Press-Fit Threaded Standoffs with Closed End
Front
Back
Also known as captive standoffs, a recess under the hex clinches the panel for a strong hold that won't push, pull, or twist out. When mounted, the hex sits flush with the surface and the closed end creates a neat, finished appearance. Use a lever press to install.
18-8 stainless steel standoffs have good corrosion resistance and may be mildly magnetic.
Zinc-plated steel standoffs have some corrosion resistance.

Press-Fit Threaded Standoffs with Open End
Front
Back
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-strong hold. The open end creates a through hole. Standoffs have excellent wear resistance and may be mildly magnetic. Use a lever press to install.

Splined Press-Fit Threaded Standoffs with Open End
Fully Threaded
Partially Threaded
Also known as captive standoffs, the splines on these bite into a panel for a permanent hold and the open end creates a through hole. They have good corrosion resistance and may be mildly magnetic. Use a lever press to install.
