These locknuts have good chemical resistance and may be mildly magnetic. The nylon insert grips the bolt to resist loosening without damaging threads. They're reusable, but their holding power lessens with each use.

Black-oxide stainless steel nuts have a dark surface color.

These nuts have good chemical resistance and may be mildly magnetic. Also known as clinch style captive nuts, press them into a drilled or punched hole with an arbor press or similar pressure tool. Installation requires access to both sides of the panel. Knurls on the bottom of the nut hold them firmly in place.

These thumb nuts have good chemical resistance and may be mildly magnetic. The head is knurled for slip-resistant controlled adjustment and the collar raises the head to make it easy to grip.
