Create threads in hard-to-work areas—where you can’t reach the back of a workpiece, or material is too thin to be tapped.

Threads float inside the retainer of these metric nuts so you can install a bolt at a slight angle to align with off-center parts.

Align off-center parts as you fasten them together—these steel press-fit nuts have floating threads, so you can install bolts at a slight angle.

Snap these nuts—also known as cage nuts—into square holes in thin material. They’re often used to mount servers and other equipment in electronics racks.

Pinch the flexible plastic casing of these nuts to add threads to thin metal. Unlike typical rigid snap-in nuts, these squeeze into a square hole from the front or back of your material.
