Mil. Spec. 18-8 Stainless Steel Narrow Hex Nuts
Choose these nuts for their adherence to strict military standards for material and construction. They have good chemical resistance and may be mildly magnetic. Also known as small-pattern hex nuts, they are about 20% narrower than standard hex nuts for use in tight spaces where standard hex nuts won’t fit.

Low-Strength Steel Thin Nylon-Insert Locknuts
These locknuts are about half the height of standard nylon-insert locknuts. Use them in light duty low-clearance applications or jam one against a hex nut to hold it in place. The nylon insert grips the bolt to resist loosening without damaging threads. They're reusable, but their holding power lessens with each use.
Zinc-plated steel locknuts resist corrosion in wet environments.

18-8 Stainless Steel Flanged Knurled-Head Thumb Nuts
These thumb nuts have good chemical resistance and may be mildly magnetic. The flange distributes the load over a large area and reduces stress where the nut meets the material surface. A knurled head provides a slip-resistant grip for controlled adjustment.

Brass Flanged Knurled-Head Thumb Nuts
These thumb nuts are corrosion resistant in wet environments, electrically conductive, and nonmagnetic. The flange distributes the load over a large area and reduces stress where the nut meets the material surface. A knurled head provides a slip-resistant grip for controlled adjustment.
Zinc-plated brass nuts are more corrosion resistant than plain brass nuts.

18-8 Stainless Steel Knurled-Head Thumb Nuts
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.
Black-oxide stainless steel nuts have a dark surface color.
