A smooth base provides more contact with the mating surface than weld nuts with projections.

Weld these nuts to stainless steel surfaces.

Use these metric nuts in channels and tight spaces where round-base weld nuts won't fit.

Also known as flat-style speed nuts, these have large sides, so they're easy to push over threads by hand.

Also known as U-style clip on nuts, these nuts have a barrel with multiple threads for secure thread engagement.

A hex- or square-shaped barrel allows these clip-on nuts to be gripped with a wrench to hold them in place when tightening a screw. They have multiple threads for more thread engagement than low-profile clip-on nuts.

These nuts are often used to secure parts on electric consoles.

Also known as flat-style speed nuts, these have a large surface to distribute loads better than standard and flanged external push rings.

Use these caps to hold components in place and protect shaft ends.

Also known as poodle rings, these thick rings have "ears" that form a large retaining surface to withstand stronger forces than other side-mount retaining rings.

Slide these rings into place by hand with a single twist for applications with high thrust loads.

Designed to slide into T-slot tracks on machine tool tables, use these nuts to secure clamps and workpieces.

After sliding the nut into a T-slot, tighten the set screw to keep it in place.

Serrated grooves grip the lip of the channel.

A spring plus serrated grooves that grip the lip of the channel provide a more secure hold than standard strut channel nuts.

There's no need for additional fasteners with these nuts—they combine a strut channel nut with a spring and a threaded stud.
