Press-Fit Threaded Standoffs


	Open End	Closed End


Fully Threaded	Partially Threaded

Create permanent connections without welding, tapping, or installing extra hardware. Press the standoff into an unthreaded hole, then clinch the head using a lever press. The recessed head clinches into sheet metal for a flush, snag-free finish that resists pushing, pulling, and twisting. Also known as captive standoffs.

Corrosion-Resistant 18-8 Stainless Steel—The choice for wet and outdoor environments, these standoffs resist rusting. They're strong enough for most jobs, but won't withstand stress as well as steel.

Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.

Open End—Create a through hole for two-end mounting or to connect longer screws.

Closed End—Get a clean, finished look and block oil and moisture from getting inside your assembly.

Miniature Splined Press-Fit Threaded Standoffs

Fully

Threaded

The smallest standoffs we offer. These press into unthreaded holes to create permanent connections without welding, tapping, or installing extra hardware. The raised splines prevent rotation, and a recessed head clinches material for a strong hold. A through hole allows installation from one side, making them ideal for compact electronics like laptops and handheld devices.

Wear-Resistant 400 Series Stainless Steel—These standoffs can grind against metal surfaces without denting or scratching. More corrosion resistant than steel.

Press-Fit Snap In Standoffs

Lock down one panel, then snap on the next. Use a lever press to clinch these standoffs into a base panel for a permanent hold. Then snap another panel onto the pronged ends.

Wear-Resistant 400 Series Stainless Steel—These standoffs can grind against metal surfaces without denting or scratching. More corrosion resistant than steel.

Splined Press-Fit Threaded Standoffs


		Fully Threaded	Partially Threaded

Create a secure, permanent hold on sheet metal panels. They're often used to mount access covers and shields onto enclosures. Splines bite into the panels so standoffs don't rotate. Also known as captive standoffs.

Splined Press-Fit Unthreaded Spacers

Create a secure hold on sheet metal panels—no threads required. Splines bite into the panel to lock the spacer in place while allowing fasteners to pass through. These spacers are often used to space or align stacked thin panels and circuit boards. Length excludes the splined end. Also known as captive spacers.

18-8 Stainless Steel—The choice for wet and outdoor environments, these spacers resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.
