These nuts sit flush in panels for a smooth surface, so they fit in cramped enclosures. You can also install them onto parts before forming them, since the head bends along with the metal. The hex-shaped head locks into holes when installed, so the nuts won't twist as you fasten screws.

The ridged knurls on these broach-style nuts cut into soft metal and plastic without deforming them. They add permanent threads to everything from soft brass panels to brittle circuit boards.

The nylon insert inside these nuts grips screws so they won't back out or loosen. Use them to keep thin parts fastened on engines and other vibrating machinery.

Fasten sheet metal without scratching or damaging nearby parts. The closed barrel on these nuts covers screws entirely once inserted and shields them from leaks and debris. Use them in electronics with sensitive components and CNC machines exposed to liquids and dust.

Fasten together parts with off-center holes. The threaded hole within these nuts shifts up to .01" in any direction, so screws pass through every time.

Fasten together unaligned parts and keep screws in place. The threaded hole within these press-fit nuts shifts up to .01" in any direction, so you can fasten together thin panels with off-center holes. The irregularly shaped threads tightly grip screws to prevent them from loosening or backing out under vibration.
